AC Gain – Stability
This potentiometer is used to adjust the AC gain of the velocity loop. There is a low-pass filter network
around the velocity loop amplifier, allowing the velocity loop to be bandwidth-limited for stability. This
pot is used to modify the exiting bandwidth. When the velocity loop compensator components are
properly selected, this pot allows some adjustment to variation in the load dynamics. Adjust this
potentiometer for best system response while maintaining servo-loop stability.
Balance – DC Offset
This pot adds a DC offset signal into the velocity loop to null any offsets in the system. In systems where
the drive is used as a velocity controller this pot is adjusted for zero motor speed when applying a zero
speed command input. In systems where the drive is used inside of a position loop, it is common to adjust
this potentiometer when the motor is at rest for a command of 0.000 volts input signal.
Current Limit
This pot is used to limit the peak current to the motor to something less than the drive’s peak current.
