MMRG Series drives have five user adjustable trimpots: MAX SPD,
ACC–DEC, FORWARD TORQUE, REVERSE TORQUE, and IR
COMP. MMRG-PCM series drives have two additional user
adjustable trimpots: FWD SPD ADJ and REF SPD ADJ. Each
drive is factory calibrated to its maximum current rating. Readjust
the calibration trimpot settings to accommodate lower current rated
motors. See Figure 14, page 26 for trimpot locations.
All adjustments increase with CW rotation, and decrease with CCW
rotation. Use a non-metallic screwdriver for calibration. Each
trimpot is identified on the printed circuit board.

Warning
Dangerous voltages exist on the drive when it is powered.
When possible, disconnect the voltage input from the drive
before adjusting the trimpots. If the trimpots must be
adjusted with power applied, use insulated tools and the
appropriate personal protection equipment. BE ALERT.
High voltages can cause serious or fatal injury.
