Short Description

Velocity Control Loop: Proportional Gain

Description

That means, that a difference between N_cmd and N_actual of 3000 rpm with GV = 1 results in the peak current of the drive.

This variable determines the proportional gain (also known as AC-gain). Adjust this variable 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 between 10 and 20. If the GV value is too low, the drive is too soft and has poor damping. If the GV value is too high, the drive whistles or runs roughly.

The gain is defined, that a velocity deviation of 3000rpm with GV = 1 results in the peak-current of the drive.
