4.4 Control Modes (P1300)
The various modes of operation of the MICROMASTER 410 control the relati on-
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 c onveyors
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 d ynamic
response of the motor.
Ø Quadratic V/f control P1300 = 2
This mode can be used for variable torque loads, such as fans and pum ps.
Ø Multi-point V/f control P1300 = 3
For information regarding this mode of operation, please consult the M M410
Parameter List.
4.5 Faults and Alarms

Standard Inverter

If an Operator Panel is not fitted, the fault states and warnings are indica ted by the

If the inverter is working correctly, the following LED sequence is visible:
Ø Flashing Yellow (1000 ms on / 1000 ms off) = Ready to run
Ø Continuous Yellow = Run

Operator Panel Fitted

If an Operator Panel is fitted, the fault states (P0947) and warnings (P2110) are
