Control Modes (P1300)
The various modes of operation of the MICROMASTER 411 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:
Linear V/f control
Can be used for variable and constant torque applications, such as conveyors
and positive displacement pumps.
Linear V/f control with FCC (Flux Current Control)
This control mode can be used to improve the efficiency and dynamic
response of the motor.
Quadratic V/f control
This mode can be used for variable torque loads, such as fans and pumps.
Multi-point V/f control
Multi-point V/f allows the user to define their own V/f Characteristics.
This characteristic uses two fixed coordinates and three pairs of variable
coordinates.
Fixed co-ordinates are:
Variable co-ordinates may be obtained from the following three pairs of
coordinates
P1320 (frequency) -P1321 (voltage)
P1322 (frequency) -P1323 (voltage)
P1324 (frequency) -P1325 (voltage)
User programmable V/f characteristics are often used to provide correct torque
at correct frequency, which can be useful when using the Inverter with
synchronous motors. See Parameter List for further detail.

Faults and warnings
LED Fault Indication
Fault states and warnings are indicated by the LED within the control potentiometer
on the inverter, see section 6.1 for further information.
BOP fitted
If a BOP is fitted, the fault states (P0947) and warnings (P2110) are displayed
should a fault condition occur. For further details, please refer to section 6.2.
AOP fitted
If the AOP is fitted, fault and warning codes are displayed on the LCD panel.
