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: 

 

P1300 = 0 

Can be used for variable and constant torque applications, such as conveyors 
and positive displacement pumps. 

 

P1300 = 1  

This control mode can be used to improve the efficiency and dynamic 
response of the motor. 

 

This mode can be used for variable torque loads, such as fans and pumps. 

 

P1300 = 3  

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:   Boost as defined in P1310 at 0 Hz. 

Nominal voltage P0304 at nominal frequency P0310 

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. 

 

Fault states and warnings are indicated by the LED within the control potentiometer 
on the inverter, see section 6.1 for further information. 

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. 

If the AOP is fitted, fault and warning codes are displayed on the LCD panel.
