AC electric drives Unidirve M400 – universal industrial Control Techniques electric drive with integrated real-time PLC, which implements a high-precision rotor flow control algorithm (Rotor Flux Control /RFC). The Unidrive M400 speed controllers are programmed using the CODESYS-based Machine Control Studio software product.
The use of the RFC algorithm ensures high stability of control of an asynchronous electric motor in open–loop mode, the overload characteristics of the electric drive for heavy duty operation are significantly expanded - up to 180% for 3 seconds or 150% for 80 seconds.
Unidrive M400 frequency converters is a new model that, starting in 2015, should replace its predecessor Commander SK. The use of a new generation of equipment allows the user to quickly and without additional modifications modernize equipment that uses Commander SK frequency converters with an extended LogicStick control module. The Unidrive M400 platform fully supports importing parameter files Commander SK.
Unidrive M400 inverters fully comply with SIL3 functional safety standards, the drive has inputs (2 pcs.) for safe torque shutdown (STO Input).
