4.4 Control Modes (P1300)
The various modes of operation of the MICROMASTER 410 control the relation-
ship between the speed of the motor and the voltage supplied by the inverter. A
summary of the control modes available are listed below:
Ø Linear V/f control, P1300 = 0
Can be used for variable and constant torque applications, such as conveyors
and positive displacement pumps.
Ø
Linear V/f control with FCC (Flux Current Control), P1300 = 1
This control mode can be used to improve the efficiency and dynamic
response of the motor.
Ø
Quadratic V/f control P1300 = 2
This mode can be used for variable torque loads, such as fans and pumps.
Ø
Multi-point V/f control P1300 = 3
For information regarding this mode of operation, please consult the MM410
Parameter List.
