1.4 Installation instructions

1.4.1 Cooling systemsThe KEB COMBIVERT F5 is available for different cooling systems:

Heat sink with cooling fan (mounted version) The standard version is delivered with heat sink and cooling fan.

Special versionsThe dissipation of power loss must be guaranteed by the machine builder.•Watercooling This version is dimensioned for the connection to an available cooling system. The dissipation of the power

loss must be ensured by the machine builder. In order to avoid moisture condensation, the minimum inlet temperature may not decrease the ambient temperature. The max. inlet temperature may not exceed 40°C. No aggressive coolant shall be used. Measures against contamination and calcination must be done externally. Max. pressure on the cooling system may not exceed 4 bar (special versions with higher pressures possible on request).

• Convection(through-mountversion) In this version the heat sink is placed externally with a cutout in the control cabinet.

CAUTION!

DO NOT TOUCH!Hot Surfaces

© 2005 KEB

In case of burn, cool inflicted area immediately and seek medical attention.

Heat sinks can reach temperatures, which can cause burns when touching. If in case of structural measures a direct contact cannot be avoided, a warning notice "hot sur-face" must be mounted at the machine.

1.4.2 Safety relay for „safety stop in accordance with EN954-1/ category 3“With the function "safety stop" one of the following conditions must be fulfilled:• the power supply to the drive must be interrupted (double security)• no torque at the drive

The KEB COMBIVERT F5 with safety relay fulfills the condition: no torque by a safe disconnection of the driver signals for the power modules (IGBT). There is no voltage disconnection.This is guaranteed by a two-channel processing holding signal. On of the channels is developed in programmed electronics. The second channel consists of an electro-mechanical relay. The function of the relay is cyclically monitored by the programmed electronics.

Through the double safety no further measure is needed for the KEB COMBIVERT (e.g. feedback relay contact) since an individual error in the control does not lead to the loss of the stop function.

1.5 Installation of water-cooled unitsIn continuous operation water-cooled inverters are operated with lower temperature than air-cooled inverters. This has positive effects on lifetime-relevant components such as fan and DC link circuit capacitors and power mo-dules (IGBT). Also the temperature dependent switching losses are positively effected. The use of water-cooled KEB COMBIVERT frequency inverters is offered in the drive technology, because there are process-caused coolants available with some applications. The following instructions must be observed absolutely when this units are used.

1.5.1 Heat sink and operating pressureDesign system Material (voltage) Max. operating pressure Connecting ductExtrusion casting heat sink Aluminium (-1.67 V) 10 bar 00.00.650-G140

The heat sinks are sealed with sealing rings and have also a surface protection (anodized) in the ducts. The heat sinks are generally maintenance-free!

In order to avoid a deformation of the heat sink and the damages involved, the indicated max. opera-ting pressure may not be exceeded briefly also by pressure peaks.Pay attention to the guidelines 97/23/EG of pressure units.

1.5.2 Materials in the cooling cicuitFor the screw connections and also for the metallic articles in the cooling circuit which are in contact with the coolant (electrolyte) a material is to be selected, which forms a small voltage difference to the heat sink in order to avoid contact corrosion and/or pitting corrosion (electro-chemical voltage series, see table 1.5.2). An aluminum screw connection or ZnNi coated steel screw connection is recommended. Other materials must be examined in each case before employment. The specific case of application must be checked by the customer in tuning of the complete cooling circuit and must be classified according to the used materials. With hoses and seals take care that halogen-free materials are used.A liability for occuring damages in case of wrong used materials and from this resulting corrosion cannot be as-sumed!Table 1.5.2 Electro-chemical voltage series / standard potentials against hydrogenMaterial generated Ion Standard poten-

1.5.3 Requirements on the coolantThe requirements on the coolant are depending on the ambient conditions, as well as from the used cooling sy-stem. General requirements on the coolant:Standards TrinkwV 2001, DIN EN 12502 part 1-5, DIN 50930 part 6, DVGW work sheet W216VGBCooling water directive

The VGB cooling water directive (VGB-R 455 P) contains instructions about common process technology of the cooling. Particulary the interactions between cooling water and components of the cooling system are described.

pH-value Aluminum is particularly corroded by lixiviums and salts. The optimal pH value for aluminum should be in the range of 7,5… 8.0.

Abrasive substances Abrasive substances as used in abrasive (quartz sand), clogging the cooling circuit.Copper cuttings Copper cuttings can attach the aluminum and this leads to a galvanic corrosion. Cop-

per should not be used together with aluminum due to electro-chemical voltage diffe-rence.

Hard water Cooling water may not cause scale deposits or loose excretions. It shall have a low total hardness (<20°d) especially carbon hardness.

Soft water Soft water (<7°dH) corrodes the material. Frost protection An appropriate antifreeze must be used for applications when the heat sink or the

coolant is exposed temperatures below zero. Use only products of one manufacturer for a better compatibility with other additives.

Corrosion protection Additives can be used as corrosion protection. In connection with frost protection the antifreeze must have a concentration of 20…25 Vol %, in order to avoid a change of the additives.

Special requirements for open and half-open cooling systems:Impurities Mechanical impurities in half-open cooling systems can be counteracted when appro-

priate water filters are used.Salt concentration The salt content can increase through evaporation at half-open systems. Thus the

water is more corrosive. Adding of fresh water and removing of process water works against.

Algae and myxobacte-ria

Algae and myxobacteria can arise caused by increased water temperature and contact with atmospheric oxygen. The algae and myxobacteria clog the filters and obstruct the water-flow. Biocide containing additives can avoid this. Especially at longer off periods of the cooling circuit preventive maintenance is necessary.

Organic materials The contamination with organic materials must be kept as small as possible, because separate slime can be caused by this

Damages at the unit which are caused by clogged, corroded heat sinks or other obvious operating er-rors, leads to the loss of the warranty claims.

1.5.4 Connection to the cooling system• Screw in connecting duct in accordance with the manual• The connection to the coolant must be carried out with flexible, pressure-resistant hoses and secured with

clamps.• Pay attention to flux direction and check tightness !• The cooling flow must always be started before starting the KEB COMBIVERT.

The connection to the cooling system can occur as closed or open cooling circuit. The connection to a closed cooling circuit is recommended, because the danger of contamination of coolant is very small. Preferably also a monitoring of the pH value of the coolant should be installed.Pay attention to a corresponding cable cross section at required equipotential bonding in order to avoid electro-

chemical procedures.

1.5.5 Coolant temperature and moisture condensationThe inlet temperature may not exceed 40°C. The maximum heat sink temperature is 60 °C or 90 °C depending on the power unit and overload capacity (see „technical data“). To ensure a safe operation the coolant output tempe-rature must be 10 K below this temperature. Due to high air humidity and high temperatures it can lead to moisture condensation. Moisture condensation is dangerous for the inverter, because the inverter can be destroyed through eventual occuring short-circuits.

The user must guarantee that any moisture condensation is avoided!

In order to avoid a moisture condensation the following possibilities can be done. The application of both methods is recommended. Supply of temper coolantThis is possible by using heatings in the cooling circuit for the control of the coolant temperature. The following dew point table is available for this:Coolant inlet temperature [°C] is depending on ambient temperature and air humidity

Temperature ControlThe cooling system can be connected by means of pneumatic or magnetic valves. A relay is frontend. In order to avoid pressure surges, the valves for the temperature control must be inserted before the cooling circuit. All usual valves can be used. Pay attention that the valves are faultless and do not clamp.

During transport or storage below the freezing point, the heat sink must be completely drained with air pressure.

Connection Terminals

2.4 Terminal strips of the power circuitAll terminal strips following the requirements of the EN 60947-7-1 (IEC 60947-7-1)

2.4.1 Mains inputThe KEB COMBIVERT is dependent on the input rectifier suitable for 3-phase mains supply (B6-rectifier-circuit) or 6-phase (B12-rectifier circuit). This can be recognized at the input terminals (see picture 2.4.1.a and 2.4.1.b). The B12 rectifier circuit is connected to two 3-phase mains supply phase-shifted by 60 degrees. This effects a reduction of the net reactions at high power. In spite of the electric advantages and increased lifetime, this net-work configuration is not often realized because of high transformer costs. The DC link of the COMBIVERT with B12 rectifier circuit is dimensioned by such way that connection to a 3-phase mains supply is also possible. The different connection methods are described in chapter „connection of the power unit“.

2.6.3 Selection of the motor cableCorrect selection and wiring of the motor cable is very important for high motor ratings:• lower abrasion of the motor bearings by leakage currents• improved EMC characteristics• lower symmetrical operating capacities• less losses by transient currents

It is recommended to use symmetric shielded motor cables at high motor ratings (>30 kW). At these cables the protective earth conductor is tripartited and uniformly placed between the phase lines.A cable without protective earth conductor can be used if the local regulations allow this. Then this protective earth conductor must be placed externally. Certain cables accept also the shielding as protective earth conductor. Pay attention to the data of the cable manufacturer!

2.6.4 Connection of the motorAs a standard the connection of the motor must be carried out in accordance with the following table:Table 2.6.4 Connection of the motor

The connecting-up instructions of the motor manufacturer are generally valid !

Protect motor against

voltage peaks !

Frequency inverters switch at the output with a dv/dt of approx. 5kV/us. Especially at long motor lines (>15m) this may damage the insulation system of the motor at high voltage peaks.The motor can be protected by a motor choke, dv/dt filter or sine filter.

1) The column is valid at factory setting and Ud.02 ≥ 4 (F5-Multi, Servo). The function must be programmed accordingly with parameters Pn.12, Pn.13, Pn.62 and Pn.72 when Ud.02 < 4 (F5-General).

2) Disconnection is depending on the adjusted temperature in Pn.62.

The behaviour of the inverter in case of error/warning is defined with parameters Pn.12 (CP.28), Pn.13, Pn.62 and Pn.72.

Dependent on the application the temperature input can be used for the following functions:Function Mode (Pn.72)Motor temperature display and monitoring KTY84Motor temperature monitoring PTCTemperature control of water-cooled motors 1) KTY84General fault sensing PTC1) If the temperature input is used for other functions, the motor temperature control at water-cooled inverters can directly occur via the water-cooling circuit of the inverter.

• Do not lay KTY or PTC cable of the motor (also shielded) together with control cable !

• KTY- or PTC cable only permissible with double shielding within the motor cable !

2.6.8 Connection of a braking resistor

Braking resistors dissipate the produced energy of the motor into heat during generatoric ope-ration. Thus braking resistors can cause very high surface temperatures. During assembly pay attention to appropriate protection against contact and fire.

The use of a regenerative unit is reasonable for applications which produce a lot of regenerative energy. Regeneration of excess energy into the mains.

The mains voltage must always be switched off in order to guarantee fire protection in case of a defective braking transistor.

The frequency inverter remains in operation in spite of switched off power supply in generatoric operation. An error must be released by external wiring which switches the modulation off in the inverter if no GTR7 evaluation is installed (GTR7 evaluation only at water-cooled units). This can occur e.g. at terminals T1/T2 or via digital input. The frequency inverter must be programmed accordingly in each case.

Only "intrinsically safe" braking resistors are permissible for operation without temperature moni-toring.

GB - 34


2.6.8.2 Braking resistor with over-heat protection and GTR7 monitoring (water-cooled inverter)This circuit offers a direct protection with defective GTR7 (braking transistor). At defective braking transistor an integrated relay opens the terminals K1/K2 and error „E.Pu“ is released. Terminals K1/K2 are integrated into the holding circuit of the input contactor, so the input voltage is switched off in error case. Regenerative operation is also secured by the internal error disconnection. All other errors of the braking resistor and the input choke are intercepted via a digital input. The input must be programmed to "external error".

If the PTC/KTY evaluation of the motor at terminals T1/T2 is not used, these terminals can be used instead of the programmable input. The temperature input must be operated in PTC mode (see 2.6.7.2).

2.6.8.3 Braking resistor with over-heat protection without GTR7 monitoring (air-cooled inverter)This circuit offers a direct protection with defective GTR7 (braking transistor). The braking resistor overheats and opens the OH terminals with defective GTR7. The OH terminals open the holding circuit of the input contactor, so that the input voltage is switched off in error case. An error in inverter is released by opening the auxiliary contacts of K3. Regenerative operation is also secured by the internal fault disconnection. The input must be programmed and inverted to "external error". Automatic restarting after cooling of the braking resistor is prevented by the self-holding circuit of K3.

If the PTC/KTY evaluation of the motor at terminals T1/T2 is not used, these terminals can be used instead of the programmable input. The temperature input must be operated in PTC mode (see 2.6.7.2).

„-“, respectively “++“ and „--“)

In order to avoid premature ageing and avoidable malfunctions, the measures mentioned below must be carried out in the appropriate cycle.

Cycle Function

Constant

Pay attention to unusual noises of the motor (e.g. vibrations) as well as of the frequency inverter (e.g. fan).Pay attention to unusual smells of the motor or frequency inverter (e.g. evaporation of capacitor electrolyte, braise of the motor winding)

Monthly

Check unit for loose screws and plugs and if necessary tighten up.Clean frequency inverter from dirt-and dust deposits. Pay attention especially to cooling fins and protective grid of the fans.Examine and clean extracted air filter and cooling air filter of the control cabinet.Examine function of the fans of the KEB COMBIVERT. The fans must be replaced in case of audible vibrations or squeak.

3.6 Shut down

3.6.1 StorageThe DC link of the KEB COMBIVERT is equipped with electrolytic capacitors. If electrolytic capacitors are stored de-energized, the oxide film working as dielectric fluid reacts with the acidic electrolyte and destroy themselves slowly. This affects the dielectric strength and the capacity. If the capacitor starts running with rated voltage, it is tried to build the oxide film abrupt again. This causes heat and gas and leads to the destruction of the capacitor.In order to avoid defectives, the KEB COMBIVERT must be started up depending on the storage period in accor-dance with the following specification:Storage period < 1 year• Start-up without special measuresStorage period 1…2 years• Operate frequency inverter one hour without modulationStorage period 2…3 years• Remove all cables from the power circuit; especially of braking resistor or module• Open control release• Connect variable transformer to inverter input

Appendix

• Increase variable transformer slowly to indicated input voltage (>1 min) and remain at least on the specified time.

Voltage class Input voltage Residence time

400 V0…280 V 15 rpm

280…400 V 15 rpm400…500 V 1 h

Storage period > 3 years• Input voltages as before, however double the times per year. Eventually change capacitors.

After expiration of this start-up the KEB COMBIVERT can be operated on nominal rating conditions or delivered to a new storage.

3.6.2 Cooling circuitThe cooling circuit must be completely empty if a unit shall be switched off for a longer period. The cooling circuit must be blown out additionally with compressed air at temperatures below 0°C.

3.7 Certification

3.7.1 CE-MarkingCE marked frequency inverter and servo drives were developed and manufactured to comply with the regulations of the Low-Voltage Directive 2006/95/EC.The inverter or servo drive must not be started until it is determined that the installation complies with the Machine directive (2006/42/EG) as well as the EMC-directive (2004/108/EC)(note EN 60204).The frequency inverters and servo drives meet the requirements of the Low-Voltage Directive 2006/95/EC. The harmonized standards EN 61800-5-1 were used.This is a product of limited availability in accordance with IEC 61800-3. This product may cause radio interference in residential areas. In this case the operator may need to take corresponding measures.

3.7.2 UL Marking

Acceptance according to UL is marked at KEB inverters with the adjacent logo on the type plate.

To be conform according to UL for the use on the North American Market the following additional instructions must be observed:• Suitable For Use On A Circuit Capable Of Delivering Not More Than 100 rms Symmetrical Amperes, 480 Volts
