Product Description:
The MICROMASTER Vector (MMV) and MIDIMASTER Vector (MDV) are a standard range of inverters with sensorless vector
capability suitable for controlling the speed of 3 phase motors. Various models are available, ranging from the compact 120 W
MICROMASTER Vector up to the 75 kW MIDIMASTER Vector.
Sensorless vector control allows the inverter to calculate the changes required in output current and frequency in order to maintain the
desired motor speed across a wide range of load conditions.
The MICROMASTER Vector and MIDIMASTER Vector inverters have four different modes of operation which control the relationshipbetween the voltage supplied by the inverter and the speed of the motor. The motor control mode of operation is selected at P077:
Linear voltage/frequency Operation.
Flux Current Control (FCC) which is used to maintain full flux conditions in the motor.
Quadratic voltage/frequency relationship which is used for pumps and fans.
Sensorless Vector. The inverter calculates the changes required in output voltage to maintain the desired motor speed.
