2.4 Inputs / Outputs operation description
I/O Features Signal interfacing is provided on the step, direction, current reduction, enable, reset inputs andhome, fault outputs.
Inputs The following figure shows the Inputs/Outputs interface schematic diagram of MPP16-V04Outputs standard version.Interface
Inputs The default setting on MPP16 is for PNP type inputs.TypeSelection PNP Inputs: To select PNP inputs: connect through JUMP1 2 and 3 pins (refer to MPP16
part location diagram) the inputs pull-down resistors to the internal DC (-) side.NPN Inputs: To select NPN inputs: connect through JUMP1 1 and 2 pins (refer to MPP16
part location diagram) the inputs pull-up resistors to internal +24Vdc powersupply.
Using NPN inputs , connect the EN input to the GND terminal to enable the driver.Using PNP inputs, connect the RST and RWC inputs to the V+ terminal to disable the Resetand the Current Reduction functions.
Using NPN style connection,input wire grounding fault can result in unwanted actuating of thedriver.
Pag. 2 - 4Doc. : HD342-00-MPP16.wpd-1.4 06-10-1999
INPUTS CK : Controls the speed of the motor according to the selected step type.The following table shows the number of clock pulse needed to achieve a turn in astandard motor with 1.8° step angle :
Step type N° of clock pulse
Full step 200
1/2 step 400
1/4 step 800
1/8 step 1600
This input is active on the Leading Edge
DIR : Reverses the rotation direction of the motor shaft.
EN : Enables/disables the motor current:
0 = Enable (Full motor current)1 = Disable (Null motor current)
RWC : Reduces by 40% the selected current value:
0 = Full motor current - 40%1 = Full motor current
RST : Resets the internal counting of the current waveform sequence.When RST input is enabled the motor rotation stops (even if the clock pulses are appliedto the CK input) and the motor holds the torque at maximum current. (See the functional diagram on page 2-6 and 2.8).
0 = Reset counting1 = Normal operation
Pag. 2 - 5Doc. : HD342-00-MPP16.wpd-1.4 06-10-1999
Outputs: FAULT and HOME PNP style outputs.type
FAULT : Monitors the status of the drive’s overcurrent/short circuit protection.During the normal operation the output is high (+24Vdc) and if anovercurrent/short circuit event occurs on the motor outputs, it switches off (Lowstate).0 = Protection state (0Vdc)1 = Normal operation (+24Vdc)
To reset the protection state : switch the power supply off, wait some secondsuntil the green led is lit off and switch power supply on.
HOME : Monitors position “zero” of the current waweform sequence (See the ‘HOME and RST signals timing diagram in section 5).
The output is normally high (+24Vdc) and switches off when zero position occursduring the counting of the current sequence.0 = Zero position (0Vdc)1 = Normal operation (+24Vdc)
Do not use this signal as position reference.If a motor stop occurs because of the load applied to the shaft while the CK pulsesare applied to the drive, the position of the rotor determined by the HOME outputsignal is not correct.
Output signals have no over-current protection.
Refer to section 6 for input/output electrical specifications.

� Unpacking and inspecting the MPP16� Installing and using the MPP16 unit safely� Selecting optional driver’s parts� Mounting the MPP16 in your installation� Connecting the input/output cables� Setting user’s adjustments
3.1 Unpacking, Inspecting and Storing
Unpacking: 1. remove the MPP16 from packing.2. check the item(s) against the packing-list. A label located on the drive identifies the unit by model version and serial number.
Inspect the unit : any transportation damages must be submitted by the buyer to the carrier.
Store the MPP16 drive in a clean and dry place with the temperature between the specified limits.
3.2 Installing and Using the Unit Safely
Safety Only qualified personnel should install the MPP16 drive, after first completely readingGuidelines and understanding the information included in this manual.
The installation instructions should be followed and approved. Any question or doubt should be clarified with the supplier of the driver before its use.
In no event will EVER co. accept liability for indirect or consequential damage andconsequences resulting from: inappropriate, negligent or incorrect installation or modificationof the driver without approval, or from incorrect connection of the MPP16 driver to the motor.
To avoid possible personal injury whenever you are working with MPP16 unit:
� Do not operate the driver without the motor case and the DC bus (-) side connected to ground.
� The protective earth (PE) impedance must conform to the requirements of local industrial safety regulations.
� Always turn power supply off before making or removing connections from the unit.
Pag. 3 - 2Doc. : HD342-00-MPP16.wpd-1.4 06-10-1999
Before handling or operating maintenance actions on MPP16 drive, wait until the LED on thedrive is switched off.
� Do not use the EN input as a safety shutdown. Always remove power to the drive for a safe shutdown.
�Take into account the heat dissipation function of some parts the MPP16 drive: using the drive in heavy application, some surfaces can have high temperature rise. Before unplugging the drive from the installation wait a proper time for cooling.
3.3 Selecting Motors and Options
Selecting a The MPP16 driver is designed for use with EVER’s line of step motors or most other twoMotor phase stepper motors. The motor’s ratings must be compatible with the output configuration and
ratings of the drive. Refer to the torque/Speed Curves in the “EVER’s Motors Catalogues” orcall EVER’s sales dept. or your local distributor for motor sizing and drive-motor compatibilityplanning.
Selecting Refer to “EVER co Drivers Catalogue” for options planning or call EVER sales dept.Options
3.4 Mounting the Driver
Cooling The MPP16 drive has surfaces that provide the cooling of its internal circuitry through their heatdissipation capability. Optimize the thermal flow between the drive’s surfaces and ambientaccording to the 'worst case’ power dissipated in your application.
EnvironmentThe drive should be installed in environment free of dust, corrosive vapors, gases and liquids.Avoid environments allowing condensation of vaporized liquids, including atmospheric moisture.Installing the MPP16 inside a cabinet, be sure that the air flow openings or the cabinet coolingsystem do not allow the internal temperature rise to exceed the maximum ambient temperatureof the drive.
Moreover any local safety regulations concerning the installation of motor drives has to beconsidered planning the location of the controller.
General Your installation should meet the following general guidelines:Mounting � Keep vertical orientation of the device.Guidelines � Avoid excessive vibration or shock.
� Provide some free space for air flow below and above the unit.� Use both 2 fixing holes on the rear heat sinking surface for mounting.
The “worst case power” (PW) dissipated in an application where Vdc is the DC bus voltage andI (A) the motor winding current setting, can be approximated as :
PW (watts) = Vdc * r2 * I(A) *0.1

4 STARTING THE MPP16 DRIVEThis section explains how to power up the MPP16 after installation.
Topics covered are:
� Testing the installation� Maintaining � Troubleshooting the MPP16 drive
4.1 Testing the Installation
Before - Check that the system is exactly of version and configuration youPowering up need (Refer to section 5).
Improper AC input range or motor current setting could result in irreparable drive damages. - Check that all settings are as you need in your application.- Check wiring and mounting to verify correct installation and integrity of the drive.
First Switch power ON and verify that the power ON green led is lit upPower upProcedure
Perform this initial power up with the motor shaft disconnected from the load. Improper wiringor undiscovered shipping damage could result in undesired motor motion.
Getting help If you need further assistance in your installation call EVER co. service dept.
4.2 Maintaining
Procedure The MPP16 drive is designed for a minimum maintenance.Remove superficial dust and dirt from the unit using only clean and dry low pressure air.

4.3 Troubleshooting
Introduction On the MPP16 system a POWER ON green led indicates that the drive is properly poweredup.
The FAULT output switches off when a overload or short-circuit occurs on the Step Motoroutputs (SM).
FaultStatusDiagram
Switch power off to restore from latched protection intervention.
Use emergency diagram and the troubleshooting table in the following page to fix andcorrect most problems. If you are not able to restore proper operation call EVER's ServiceSupport.
When the MPP16 switches to the FAULT state, the power stage disables and the motorloses the holding torque. The planner of installation must provide a safety device to preventany damage to things or persons if the load drags the motor.
When over current protection occurs : switch the driver off and fix the problem beforepowering the device up again.
Suspecting the MPP16 system has been damaged, before replacing it with a new unit checkthat the installation and the power supply design meet all requirements. Tentative fault corrections by simply replacing a MPP16 unit are not a good troubleshootingpractice.

Additional on CN4 expansion connector, 3 additional inputs signals are available:.Inputs
CK-AUX : Auxiliary Clock input with the same electrical characteristics as CK input, but withreversed rotation direction.This input can be used only as NPN input type.
M1,M2 : Leaving the dip-switch DP1 OFF, these inputs can be used by the expansionboard to change the step size ‘on the fly’ while the motor is running.To change step size, apply a +5Vdc or 0Vdc to these inputs referring to the tableof step size selection in section 3.6 (M1 = SW2, M2 = SW1).
Remarks The COM terminal on the CN4 connector is connected to the “common side” of the inputresistors.Connecting the JUMP1 on the PNP or to the NPN position (refer to 3.6 section), GND or V+(internal DC bus) are connected to the COM terminal on CN4.
