Description: Sets the signal source for the scaling of the P gain of the speed controller. This also makes the effective P gain
(including adaptations) scalable.
Description: Displays the effective P gain of the speed controller.
Description: Displays the effective integral time of the speed controller.
Description: Sets the P gain for encoderless operation for the speed controller.
Note: The product p0341 x p0342 is taken into account when automatically calculating the speed controller (p0340 = 1, 3,
4).
Description: Set the integral time for encoderless operation for the speed controller.
Note: The integral component is stopped if the complete controller output or the sum of controller output and torque pre-
control reach the torque limit.
