Functional Description

The parameter represents the integral gain of the controller. 100 % is the default value in relation to the winding resistance of the motor.

NOTE: Usually, there is no need you to modify this parameter since the controller gain is automatically adapted to the motor internally.

Exception: If a small motor (low peak current) is connected to a large device (high peak current), the occurring current ripple may cause interferences. In this case, the parameters Curr_P_Gain and Curr_I_Gain can be reduced.

NOTE: The parameter value is transferred from the master to the slave via the parameter channel of the Sercos at every access. Typically, this takes about 10 ms. However, times up to 1 s may be realized if large amounts of data are transferred on the parameter channel.

This parameter has no effect for asynchronous motors in open-loop V / f mode (ControlMode = open-loop control / 1).
