Short Description Proportional Gain of the Velocity Controller


This variable is used only for the PI position control loop (EXTPOS=0, 2). Adjust GPV by increasing the value to the level where the motor starts to oscillate. Then, back it off until the oscillations have clearly stopped. Typical values are the same as for the GV gain of the velocity controller. If the GPV value is too low, the drive is too soft and has poor damping. If the GPV value is too high, the drive whistles or runs roughly.
