Calibration
Warning
Dangerous voltages exist on the drive when it is powered.
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.
ƽ
Each drive is factory calibrated to its maximum current rating.
Readjust the calibration trimpot settings to accommodate lower
current rated 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
Figures 18 and 19 (pages 41-42) for typical TORQUE LIMIT and
IR COMP settings.
