depicted on the next page, should accompany the return, after it has been filled out, to indicate all problems and faults which occurred. If no repair card is available, then just make a copy of the following page, fill it out, and return it with the defective part. A short description of the faults and problems which occurred should, in any case, accompany the return to guarantee a quick and effective repair.The INDRAMAT AC drive system consists of a supply and a drive module. Several drives can be mounted to a single supply module. Supply module KDV 4.1, with its feedback capability, is a component of the INDRAMAT modular AC drive system. Supply module KDV 4.1 provides the link circuit d.c. voltage for the power supply and the control voltages for all connected INDRAMAT spindle- and servo-drive modules.

The controlled three-phase bridge of the KVD 4 rectifies the mains alternating current. Buffer capacitors provide sufficient smoothing. In the event that the drives are run with a generator, the KDV 4 will function as an inverter. In the event of power failure or if the power supply should be switched off, then the energy fed back as a result of the braking of the motors will be assimilated by the bleeder resistor, which is switched parallel to the buffer capacitor. The KDV 4 provides the +24VL and +/- 15VM for all connected drive modules. In the event of power failure, Power is supplied to the electronics by the link circuit d.c. voltage. As a result, the drive electronics can still function when the drive runs as a generator.

Monitoring the Drive Systems

The KDV 4 has been equipped with extensive control functions. These communicate with the drive modules over the signal voltage bus. The Bb1-contact of the KDV 4 is of ultimate importance to the operational readiness of the drive systems. Powering down is possible only after it closes.

Area of Application The KDV 4 with mains feedback is an economical solution for continuous drive power starting at approximately 10 kW and continuous feedback power greater than 1kW. The KDV4 needs no power transformer for mains voltages from 3 x 380 ... 460V, 50 ... 60 Hz. Supply module KDV2, with built-in 2-kW-bleeder resistor, is available for smaller continuous feedback requirements.• It is possible to operate the drives for extended duty cycles even while braking. The energy produced by braking the motor is fed back into the mains with little loss. • The mains voltage of the power supply is variable over a wide range A power supply of 3 x 380 ... 460V, 50 ... 60Hz is possible. A power transformer is not required in most cases. • The drive system’s response to a power failure can be programmed by providing an external bridge - – without the bridge, the drives brake at maximum torque; – with the bridge, a signal is sent via a zero potential contact to the CNC control. The CNC control then guides the powering down of the drives. Expensive tools or instruments are protected against damage.
