Additional Tuning Adjustments
Internal Resistance Compensation ( IR COMP )
Compensation pot is used to overcome the motor’s natural tendency to slow
down as the load increases. If the motor slows down excessively as it is loaded, adjust
the IR COMP pot clockwise to recover speed lost during the loaded condition. The
motor will oscillate in speed or “hunt” if the IR COMP pot is adjusted too far clockwise.
If this pulsing of speed occurs, adjust the IR COMP pot counter clockwise until the
motor speed stabilizes.
