DETAILED PARAMETER DESCRIPTION
Description:
It limits the value of the motor current component that produce torque. The adjustment is expressed in per-
centage of the inverter rated current (value of parameter P0295).
During the current limitation process, the motor current can be calculated by:
I
motor
=
√
( P0170 or P0171 )
2
+ ( P0410 )
2
During the optimal braking, P0171 acts as the limitation of the maximum output current to generate the forward
braking torque (refer to P0151).
Although the value of P0170 and P0171 depends on the relation between P0295 and P0401, its value is limited
to 250 %.

NOTE!
This parameter is only visible on the HMI when: the control type is vector, P0202 = 3 (Sensorless
Vector) or P0202 = 4 (Vector with Encoder).
P0175 - Flux regulator proportional gain on the motor
P0176 - Integration constant of the flux regulator on the motor
Adjustable range: P0175 = 0.0 to 999.9
P0176 = 1 to 9999 Factory setting: P0175 = 50.0
P0176 = 900
