NRG-2Q Series drives have seven user-adjustable trimpots. Each
drive is factory calibrated to its maximum current rating. Readjust
the calibration trimpot settings to accommodate lower current
motors. See Figure 8 for trimpot location.
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.
Calibration
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.
