External electronic performance monitoring for electromotive drive units.
MMC detects the current drawn (I), the supply Voltage (U) and the phase angle (cos φ) of the drive motor under operating conditions. Through compensation adjustment of the internal resistance of the motor windings (Ri) the actual power output of the control motor to the machine/unit is selected. Operating parameters of min. and max. power output can be exactly adjusted and pre-selected. If the pre-set values are over or under attained, the machine is switched off immediately. Analog signals are transferred to the analog output and can be utilized as control signals.
The MMC protects against damages resulting from operational failures or errors by precise monitoring of both overload and underload conditions:
