8 Don’t install the drive in places where water pipes may leak onto it.

2.2 Wiring 1 Only qualified personnel shall wire the drive.

2 Never wire the drive unless the input AC supply is totally disconnected.

3 The drive must be properly earthed to reduce electrical accident.

1 Don’t confuse the input and output terminals, otherwise there is an explosion or property may be damaged.

2 Don’t short circuit P and N, otherwise there is a danger of fire or property may be damaged.

3 Cable lugs must be connected to main terminals firmly, otherwise property may be damaged.

4 The bare portions of the power cables must be bound with insulation tapes.

For your safety, please pay particular attention to marks used in the manual.

Danger: Operations without following instructions can cause personal injury or death.

Warning: Operations without following instructions can cause personal injury or damage to product or other equipment.



2.3 Power On 1 Install the cover before switching on the drive, to

reduce the danger of electric shock and explosion.

2

For drives that have been stored for longer than 2 years, increase its input voltage gradually before supplying full rated input voltage to it, in order to avoid electric shock and explosion.

3 Don't touch the live control terminals with bare hands.

4 Don’t operate the drive with wet hands.

2.4 Maintenance 1 Perform the maintenance job after confirming that

the DC Bus voltage is below 36V.

2 Only trained professionals can change the components, it is prohibited to leave wires or metal parts inside the drive so as to avoid the risk of fire.

3 Parameter settings of the control board that has been changed must be revised, otherwise accidents may occur.

2.5 Others 1 Modification is strictly prohibited without permission.

2 Disposing unwanted drives must as industrial waste, strictly prohibit set on fire.

2.6 About Mechanism Load

1

Driving a common motor at low speed for a long time, the drive’s life will be reduced due to the deteriorating heat dissipation effect, so a special variable frequency motor is needed if long time operation with constant torque is required.

2

The drive can protect the motor from over-temperature. If the ratings of the driven motor are not in compliance with the drive, be sure to adjust the protective threshold to ensure the motor is properly protected.



3

When running the motor above 50Hz, there will be increase in vibration and noise. The rate at which the torque is available from the motor is inversely proportional to its increase in running speed. Ensure that the motor can still provide sufficient torque to the load.

4

Braking torque is developed in the machine when the drive is hoisting a load down. The drive will trip when it cannot cope with dissipating the regenerative energy of the load. Therefore, a braking unit with proper parameters setting in the drive is required.

5 The output current may fluctuant when drive reciprocating load, especially running in low frequency, recommend running at more than 20Hz.

6

The drive system may encounter mechanical resonance with the load when operating within certain band of output frequency. Skip frequencies have been set to avoid it.

7 Don’t connect or disconnect the motor when the drive running, otherwise will lead to over current or the main circuit may be damaged.

8 Please don’t close to the motor when you use the failure re-start function.

9 Please check the speed allowance range between the motor and mechanism because AC drives can run to high speed easily.

10 Disconnect the motor cable from AC drive before any test to cables.

11 Confirm safety before changing the motor direction.

12 Insure motor terminals not be connected to main power supply.

13 The motor max speed (frequency) must be set according to the motor and devices which connected to the motor.

14Install the motor correctly and ensure the mechanism load can allow the motor start before the motor running.

15 ETD 750 AC drives must be properly earthed from ground terminal.



2.7 About AC Drives

1

Don’t connect any varistor or capacitor to the output terminals of the drive, because the drives’ output voltage waveform is pulse wave, otherwise tripping or damaging of components may occur. As following figure:

2 The drive is not suitable to be used out of the specified range of operation voltage. If needed, please use suitable voltage regulation device.

3 There are transient surge suppressors inside the drive which protects it against lighting strike.

4

When using one drive with more motors, we should pay attention to motor load can’t be a reciprocating load, otherwise it will bring instability, and for each motor must have a separate over-current protection device.

KM1~KMn must be matching with motor M1~Mn rated value, in this case, Ac drives can’t protect a single motor.

5 When the Ac drive connected to the power supply, don’t do any measurement to the internal circuit.

6 Ac drives have large capacitive leakage current.

7

When the ac drive connected to the power supply, even if the motor is not running, motor U, V, W terminals and DC Bridges / braking resistor terminals P + / PR is still charged.

KM3

KMn



8

Although the control I / O terminals and power supply isolation, even if the inverter does not power on, but the relay outputs and other I / O terminals is still possible with a dangerous voltage.

9 If the inverter is used as a part of the machine, the machine manufacturer must provide the machine's main power switch.

10

When the altitude more than 1000 meters, the inverter need for derating due to the thin air cause the inverter cooling effect deterioration. Following is the inverter rated current and altitude curves.

11

When the ac drive connected to the power supply, the inverter power unit is charged. It will be extremely dangerous and even death if touch this voltage. Control unit and the main voltage isolation.

12 Can only use spare parts supplied or recommended by ETD company.

13 ETD750 inverter can only used in a fixed installation.

14Don’t do any voltage test for any part of ETD 750.This test requires a special test procedure. Neglect of the steps will lead to devastating results.

(3) Function Description of Main circuit Terminals: Terminal Symbol Description

R/L1 S/L2 T/L3

Connect to single/three phase AC power supply.

Main circuit power supply terminals R/L1、S/L2、T/L3 are

connected to single/three phase AC power supply from circuit

protection breaker or creepage protection breaker. Needn’t to

consider the phase sequence of three phase power supply.

Proposed to connect an electromagnetic contactor in order to

remove power supply and prevent failure expansion when the

drives protect function working.

Don‘t use the main power supply “ON/OFF” to control the

operation of drive’s. Should be using S1 and S2 of control circuit

or “START” and “STOP” on operator panel to control the operation

of drives. If must use the main power supply “ON/OFF” to control

the operation of drive, then only once per hour.

200v grad input power supply: Single/three phase input sharing,

select any two of three terminals for single phase.

400v grad input power supply: No need single phase power

supply.



Terminal Symbol Description

U/T1 V/T2 W/T3

Connect to three phase motor.

Connected AC drive’s output terminals to three phases motor

according to the right phase sequence. Change any two of U, V,

W wires if the motor rotation direction is not right.

If wires between drive and motor is very long, due to

distributed capacitance between lines have a greater

high-frequency current may result in over-current trip.

Otherwise, as the creepage current increasing the current

precision become bad. So the wire length between drive and

motor should less than 50 meters for drives below 3.7kW and

for the bigger drives should less than 100 meters. If the wire is

very long, you should connect filter options (OFL filter) on the

output side.

Drive’s device at the switch process will produce a surge

voltage when the drive driven motor, this surge voltage is

superimposed on the motor terminals. For 400v series, the

surge voltage may make the motor insulation deterioration if the

wire is very long. For 400v grade please consider the following

countermeasure:

Use enhanced insulation motor;

Connect filter options (OFL filter) on the output side;

To minimize length of connection wire between the drive and

the motor, such as 10~20 meters.



Terminal Symbol Description

P+

resistance (Options)

Brake unit terminals P+、N-connected to P+、N- of drive. The

wire should less than 5 meters and double-twisted or

two-adhesion.

Drive terminals P+, N- when noted used, should maintain its

original open state.

Note: If shorted P+, N- or connected brake resistance to P+, N- ,

this will damage the drives and cause accidents. Absolutely

can’t do so.

The auxiliary contacts 1 and 2 have polarity difference.

About the connection of power regeneration unit please refer

the product manual of power regeneration unit.

EG

Grounding terminal of drive should be connected to ground.

Grounding terminal EG of drive must connected to ground for

safety and reduce noise.

In order to avoid electric shock and fire accident, the metal shell

and frame of electric device should be connected to ground

according to the national electric rule. The grounding wire

should be thick and short and drive system need to be

connected to special grounding.

Note: A、The main circuit wires is 600V IV plastic isolation.

B、Ambience temperature is 20 for recommended wire area.

C、Wire maximum section area is maximum section area of connection

terminal plate.

Be sure to connect MCCB circuit breaker between power supply and

input terminals (R/L1, S/L2, T/L3).(Please use the creepage breaker which

have high frequency countermeasure)

Needn’t consider the phase sequence of wires connected to input

terminals (R/L1, S/L2,T/L3).

Right connect wires between motor and output terminals of drive (U/T1,

V/T2, W/T3).

Terminals of power lines, motor lines and control lines, please use the

pressure with a casing joint.

Input and output line length to 10 meters as the base, if more than 10

meters, use the recommended wire cross-sectional area than the thicker

wires.

Wires connected to control circuit terminals should use shield wire or

intertwist wire, in addition, the wiring should be fully away from the main

circuit, high power circuits (including the 200V relay sequence circuit).

Please use relay of small-signal or double contacts to prevent poor

contact relay which connected to the control circuit terminals.

Grounding terminals should be effectively grounded.

ETD750 Series Universal Vector Inverter USAGE OF OPERATION PANEL


6. USAGE OF OPERATION PANEL ETD750 series inverter has LCD and LED two kinds of operator panel.

The standard LCD operator panel has a 128 * 64 array LCD display which can

be used to indicate the inverter operation status, operation direction(except for

drives below 3.7kw), alarms, pre-alarm information, Loc/Rem control, I/O

status and parameters setting. Also can choose LED operator panel, for the

detail please refer to introduction of LED operator panel on Chapter 6.4.

The operator panel is removable, and isolated from the power line. The

operator panel support plug-and-play, and can be removed during operation,

but it is suggested not to remove the keypad if the inverter is controlled by the

panel.

ETD750 Series Universal Vector Inverter SIMPLE OPERATION


7. SIMPLE OPERATION 7.1 Inspection and preparation before running

Be sure to check the following items before start: Check the wiring is right or not. Especially check the output terminals U/T1、V/T2、W/T3 can’t connect to power supply, and ensure the grounding terminal is properly earthed. Confirm terminals or the exposure electrification parts are not short-circuited or short to the ground. Confirm terminals connections, pluggable connectors and bolts not loose. When connect to the power supply, make all the switches in open state and ensure the inverter can’t start and there are no unexpected actions. Check the following items after connect to the power supply:

No failure showed on the operator panel. No foreign body in cooling fan of inverter and wind channel

unobstructed.

Switch on the power supply after the cover board be installed. Can’t remove cover board when the power supply on. Can’t operate switches with wet hands to prevent electric shock accidents.

7.2 Operation Methods There are various operation methods, please refer to description of

“Chapter 6 Usage of operation panel” and “Chapter 8 Function parameters list”. Choose the most appropriate operation method according to application requirements and operation requirements. Operation of commonly used methods such as Table 7-1

7.3 Commissioning Verify that no abnormal situation, the right set up all the function

parameters for the inverter running. Do commissioning after set all the parameters done.

ETD750 Series Universal Vector Inverter SIMPLE OPERATION


It is recommended running at lower frequency, no abnormal situation then gradually increase running frequency. Default setting to REM3 (remove control), can set by parameter “003” or switch by STOP key.

Table 7-1，Normally used operation methods:

For start press START key, for stop press STOP key. Check following items when running:

Motor rotation direction is right. Motor rotation is smooth (no howling or vibration)。 Acceleration/deceleration is smooth.

If no abnormalities then you can increase frequency from pulse knob .After the commissioning that can be put into operation.

If the inverter or motor operation exception occurs, should immediately stop running and refer to “Chapter 10 Failure Countermeasure” to verify the reasons for abnormal conditions. After the inverter stop output, terminals R/L1，S/L2，T/L3 still live if not disconnected the main contactor. At this time touch terminals U/T1、V/T2、W/T3 will be shocked. In addition, even if remove the main power supply, because of there is charging voltage on filter capacitor, it will take some time to discharge voltage. After remove main power supply 10 minutes and measure the middle dc circuit voltage by multi-meter, confirm the voltage is lower the safety voltage then can touch the internal circuit of inverter.

0: Parameters are allowed to be changed. 1: Parameters can not be changed. (Protect user’s parameters.) 2 ~ 6: reserved 7: change all parameters to default values. If the user changed the parameters by mistake and can not restore them properly, this function should be implemented. Set this parameter to 7, and then press "ENTER" button, you can make all the function code data values back to the initial value, and then re-set the required parameters.

001 Control mode Range: 0 ~ 1 Default: 1 0: V / F control. 1: Sensor less current vector control. In this move, the torque response can be improved and provide a high performance.

002 G / P options Range: 0 ~ 1 Default: * 0: G-type constant torque, overload 150% for 1min 1: P fan pump-type, overload 120% for 1min Note: Changing this parameter, No 099 parameters will subsequently change. The inverter rated power will shift to an upper grade if you change this parameter from 0 to 1.

003 Mode of operation Range: 0 ~ 8 Default: 3 ETD750 has 2 operate modes, LOCAL and REMOTE. Only when the inverter is stopped, these two control modes can be switched by pressing the "STOP" key. The selected mode can be confirmed by the control mode status indication shown on the keypad panel. The default setting is REMOTE (frequency reference from FV and FI, and the “start” and “stop” command from the terminals.) The Multi-function terminals S3-S8 works under both modes. LOC: The reference signal and running commands are from keypad panel. REM: The reference signal and running commands are assigned as the following table shows:

For example: the variable corresponding to the maximum frequency is 1.60, and then this parameter should set to 2160. In the constant pressure water supply applications, the target pressure value 1.60Mpa can be displayed together with No 015 parameter settings.

007 Ways to stop Range: 0 ~ 3 Default: 0 Select the desired stopping method: 0: decelerate to stop using 1st Dec time (default value) 1: coast to stop 2: coast to stop using 1st Dec time 3: coast to stop using 2nd Dec time Settings: 0 with the first deceleration time, deceleration to stop (factory



setting)

When the stop command is applied, the inverter will decelerate according to Dec time 1, and apply DC braking when the output frequency reaches the braking frequency, while the over-voltage (OU) alarm may occur during the deceleration if the Dec time is too short or the load inertia is too big. In this case, the Dec time should be increased or a braking resistor should be installed. Braking torque: About 20% of motor rated torque if no braking resistor, 150% of motor rated Torque if the braking resistor exists. Setting: 1 coast to stop

Output Instruction

Run command

When the stop command input inverter output disconnect

ON OFF

The motor begin to coast when the forward/reverse running instruction is canceled. Setting 2: coast to stop using 1st Dec time

Example: coast to stop using 1st Dec time: After the “stop” command applied, the inverter does not response to the “start” command within the 1st

Dec time. If the “start” command is applied, the inverter will run again after 085 (minimum base block time).



Set 3: coast to stop using 2nd Dec time

008 Stop key Range: 0 ~ 1 Default: 1 0: STOP button is valid only when the inverter is controlled by keypad. 1: STOP button is valid in any cases.

009 Confirmation Key Range: 0 ~ 1 Default: 1 0: It’s no need to press “ENTER” for confirmation when changing frequency by keypad. 1: It’s necessary to press “ENTER” for confirmation when changing frequency by keypad.

Example: coast to stop using 1st Dec time: If the “start” command is applied within the deceleration time, the inverters will not response to the commands until the Dec time elapsed. The “start” command is invalid with the Minimum BB time.

MODBUS Communication protocol

Modbus communication protocol is applied to electronic controller on the lingua franca. With this agreement, the controller between the controller via the network (such as Ethernet) and other devices can communicate. It has become a common industry standard. With it, different manufacturers of industrial control equipment can be connected into a network for centralized monitoring. This agreement defines the use of a controller can recognize the message structure, regardless of what network they are communicating through. It describes a controller requesting access to other equipment, if the response to requests from other devices, as well as how to detect the error and recorded. It sets the pattern and content of the message the public domain format. When a modbus network traffic, this agreement and decision of each controller, the device need to know their address, identify the address sent by the news and decided what action to generate. If you need to respond, the controller will generate feedback and use Modbus protocol issue. In other networks, messages containing Modbus protocol into the network used in this frame or packet structure. This conversion has also expanded the network address according to specific section addresses, routing paths and error detection method. ETD750 series of AC motor drives using the Modbus networks communication protocols. The Modbus can use the ASCII (American Standard Code for Information Interchange) or RTU (Remote Terminal Unit) two kinds of data coding. ASCII code is the data to be transmitted into the first and then send the corresponding ASCII code, while the RTU is to send data directly, without undergoing conversion. The following instructions encoded ASCII data format.

Each byte is a combination of 2 ASCII characters. For example: value is 64 Hex, ASCII representation of way for '64 ', respectively, by '6' (36Hex), '4 '(34Hex) combination. The following table shows ASCII characters '0 '... '9', 'A' ... 'F' in Comparison

generally use 5-10K potentiometer.

13.4.2 Usage explanation

External adjustable potentiometer generally has three contacts, namely

potentiometer

fixed resistance

side A, B, and

adjustable side

C (as shown): A and B is

maximum resistance sides of adjustable potentiometer, the resistance value

is the same as marked resistance. Judgment method: Sum of resistance A C

and BC equal to resistance AB, that is to say: AB=AC+BC. For this method

can judge adjustable side C, and then connected C to FV (analog input), A

and B separately to FC and FS.

Examples: Example 1：Internal control of multi-speed:

NOTE: If adjustable side C is wrong connected to FC or FS, it will lead to external frequency setting lost for longer use!

Remarks: (1) Use 054-060 to control the running time for each phase (2) Automatically cycle 053=2 (3) After the running instruction is given, it shall stop after one round running according to the setting curve Example 2: Coupling for many inverters Mode 1: The main frequency of the main and subsidiary inverters shall be effective under the external operating mode.

Graph 1



Mode 2: the operating modes for the main and subsidiary inverters can be chosen causally, the main frequency operating mode for the subsidiary inverter are controlled externally.

Graph 2

Mode 1: the frequency can be set by the potentiometer, as shown in

graph 1, achieve the coupling functions for multi-inverters by setting the

frequency of potentiometer, when the 1st inverter can not function

normally, adjust the potentiometer to make the following inverters to go on

working. Set the scale parameters of 045upper frequency to achieve the

output of the rotation rounds for two inverters can be output as certain

proportion

Mode 2: as shown in graph 2, the coupling of multi-inverters can be

achieved, if the first one can not work, other inverters shall stop working.

Use the main inverter to control subsidiary ones, connect the FC on main

inverter with the FC on the subsidiary inverter, and connect FMAs on the



main with the FV on the subsidiary. Refer to the functions and increment

of the 079 FMA and 080FMA, adjust the operating mode and control

proportion of subsidiary inverter. E.g, set the 079 as 0, 080 as 0.80, which

means to use the frequency of the main inverter to control the subsidiary

inverter. The proportion is 80%, the main inverter is 50HZ, subsidiary is

40HZ, it can be effective under the operating of the main inverter, there

are some losing for the output of the FMA, which can be solved by add

the increment of the FMA.
