Axor’s CD 180 four quadrant servo-drive comes complete with its own power supply, regenerative circuit and internal fan cooling for a power range up to 50A continuous, 180Vdc.

Because of the internal generation of the auxiliary voltages, only a three phase transformer with one secondary is enough for their supply. Auto transformers are also allowed.

Usually the CD 180 servo-drive doesn’t require an external choke before the motor, thanks to its 5 KHz special frequency “cross-modulation”. Easy-to-use and extremely reliable, it is an ideal solution for retrofit applications.
