I/F Control [93] - WEG CFW-11 Programming Manual

Description:
This parameter defines the value of the maximum output voltage. Its standard value is defined in the condition of
the nominal supply voltage.
The voltage reference used in the regulator "Maximum output voltage" (see the illustration 11.1 or 11.2) is directly
proportional to the voltage supply.
If this voltage increases, the output voltage will then be able to increase to the adjusted value in the parameter
P0400 - Nominal Motor Voltage.
If the voltage supply decreases, the maximum output voltage will decrease in the same proportion.

P0182 – Speed for i/f control actuation
Adjustable 0 to 90 rpm

Description:
It defines the speed below witch the transition form the sensorless to the control I/f occurs.
The minimum recommended speed for the sensorless vector control operation is 18 rpm for 60 Hz rated frequency
IV pole motors and 15 rpm for 50 Hz rated frequency IV pole motors.
Note!
For P0182≤3 rpm the I/f function will be disabled and the inverter will remain always in the
sensorless vector mode.
