  • Page 29: Connection Of A Braking Resistor

    Connection Power Unit 2.7.5 Connection of a braking resistor Braking resistors dissipate the produced energy of the motor into heat during generatoric operation. Thus braking resistors can cause very high surface tem- peratures. During assembly pay attention to appropriate protection against con- tact and fire.

    Connection Power Unit 2.7.5.2 Braking resistor with over-heat protection and GTR7 monitoring (water-cooled invert- ers) 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 volt- age is switched off in error case.

    Connection Power Unit 2.7.5.3 Braking resistor with over-heat protection and GTR7 monitoring (air-cooled inverters) 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.

On exceeding a load of 105% the overload integrator starts. When falling below the integrator counts backwards.

  • Page 33: Calculation Of The Motor Voltage

    Due to the leakage current the oxide layer is unrenewed. If the capacitor starts running with rated voltage there is a high leakage current which can destroy the capacitor. In order to avoid defectives, the KEB COMBIVERT must be started up depending on the sto- rage period in accordance with the following specification: Storage period <...

    This has positive effects on lifetime-relevant components such as fan and DC link circuit capacitors and power modules (IGBT). Also the temperature dependent switching losses are positively effected. The use of water-cooled KEB COMBIVERT frequen- cy inverters is offered in the drive technology, because there are process-caused coolants available with some applications.

  • Page 39: Connection To The Cooling System

    • 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 con- nection to a closed cycle cooling circuit is recommended, because the danger of contaminati- on of coolant is very small.
