Calibration
The 175326.00 has ten user-adjustable trimpots. Each
drive is factory calibrated to its maximum horsepower
rating. Re-adjust the calibration trimpot settings to
accommodate lower horsepower motors. See Figure 16
(page 32) for trimpot locations.
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.
