LEESON FHP Series Chassis Mount Variable Speed Drives - Manual (Page 54)

Calibration
The FHP series has five user-adjustable trimpots. Each
drive is factory calibrated to its maximum current rating.
Re-adjust the calibration trimpot settings to accommodate
lower current motors. See Figure 24 (page 45) for FHP
series trimpot location.
All adjustments increase with clockwise (CW) rotation and
decrease with counter-clockwise (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, and up to 60 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.
