WARNING
Use a non-metallic or insulated adjustment tool (such as a television
alignment tool) for internal adjustments. Circuit components are not at
ground potential and accidental short circuiting and shock hazard may
occur with conducting tools. Adjustment should be made only by
qualified service personnel.
Internal Adjustments
Your control has been factory-adjusted for the following settings:
Minimum speed: 0 RPM
Maximum speed: ABL-3912E: 2500 RPM; ABL-3913E: 10,000 RPM
Acceleration: ABL-3912E: 2 seconds; ABL-3913E: 5 seconds
Deceleration: ABL-3912E: 2 seconds; ABL-3913E: 5 seconds
Torque: 200% of rated (based on DIP switch settings)
Refer to Figure 1 for the trim potentiometer locations and approximate initial
settings. If you need to readjust the control for your specific applications,
proceed as follows:
Minimum and Maximum Speed:
The MIN and MAX trim potentiometers have been factory calibrated. The
lowest MIN trim potentiometer setting (fully counterclockwise) corresponds
to 0 RPM and the highest MIN setting (fully clockwise) corresponds to
approximately 30% of rated speed.
The lowest MAX trim potentiometer setting (fully counterclockwise)
corresponds to 60% of rated speed and the highest MAX trim potentiometer
setting (fully clockwise) corresponds to approximately 120% of rated speed.
Refer to Figure 1 for trim potentiometer location and settings. Adjustment of
the MIN and MAX trim potentiometers may have to be repeated several times
to arrive at the desired speeds.
NOTE: Increasing the MIN potentiometer setting will increase the maximum speed beyond
nameplate speed. The MAX trim potentiometer will need to be readjusted.
