Each drive is factory calibrated to its maximum armature voltage
and current rating. Readjust the calibration trimpot settings to
accommodate a motor with a lower armature voltage and current
rating.
All adjustments increase with clockwise rotation (CW), and
decrease with counter-clockwise rotation (CCW). Use a non-
metallic screwdriver for calibration. Each trimpot is identified on the
printed circuit board (see Figure 12).

Warning
Dangerous voltages exist on the drive when it is powered,
and up to 30 seconds after power is removed and the motor
stops. 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.
