11.8.4 I/f Control
P0182 – Speed for I/f Control Activation
Adjustable
Range:
0 to 90 rpm Factory
Setting:
18 rpm
Properties: Sless
Access groups
via HMI:
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.
P0183 – Current in the I/f Mode
Adjustable
Range:
0 to 9 Factory
Setting:
1
Properties: Sless
Access groups
via HMI:
Description:
It defines the current to be applied to the motor when the inverter is operating in the I/f mode, i.e., with the motor
speed below the value defined by P0182.
