8. Remove power from the drive.
9.
Remove the lock from the motor shaft.
10. Remove the ammeter in series with the motor armature.
ACCELERATION (ACCEL )
The ACCEL setting determines the time the motor takes to to
ramp to a higher speed. See Specifications on page 1 for
approximate acceleration times. The ACCEL setting is factory set
to its minimum value (full CCW).
Turn the ACCEL trimpot CW to increase the acceleration time,
and CCW to decrease the acceleration time.
DECELERATION (DECEL)
The DECEL setting determines the time the motor takes to ramp
to a lower speed. See Specifications on page 1 for approximate
deceleration times. The DECEL setting is factory set to its
minimum value (full CCW).
Turn the DECEL trimpot CW to increase the deceleration time,
and CCW to decrease the deceleration time.
Calibration procedure conclusion
This concludes the calibration procedure. The control should
now be calibrated for optimum operation.
