Rockwell Automation DC3E Non-Regenerative DC Drive User Guide 1/4 - 2 HP, 115/230 VAC - Manual (Page 56)

These DC3N drives have seven user adjustable trimpots.
Each drive is factory calibrated to its maximum
horsepower rating. Readjust the calibration trimpot
settings to accommodate lower horsepower motors.
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. Refer to Figure 12 for trimpot locations.
Calibration
ATTENTION: 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.
ATTENTION: The control circuit is at line potential
when the drive is energized. Exercise extreme caution
as hazardous voltage exists.
