Variable speed drives

    These "plug-and-play" variable speed drives (VSD) are compact and open to automation systems, with integrated Modbus and CANopen, they respect local specificities and requirements for processes and control (voltage ranges, positive and negative logic, control type, etc.). Variable speed drives include about 150 integrated functions for setting VSD attributes.

    Their advantage is a possibility of connection to a PLC control system, whereby a smooth change in rotation, based on technologic process parameters acquired from the control system, can be achieved. It is also possible to extend VSD with an expansion card creating thus a true PLC (programmable controller)
