ACCELERATION (ACCEL)
The ACCEL setting determines the time the motor takes to
accelerate 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).
To calibrate ACCEL:
1. Set the ACCEL trimpot full CCW.
2. Apply power to the drive and turn the main speed adjust
potentiometer full CW. If an input voltage signal is used instead
of a speed adjust pot, set the input signal to maximum. Note
the time that the drive takes to accelerate to the desired speed.
3. Adjust the ACCEL trimpot until the desired acceleration time is
reached. Turn the ACCEL trimpot CW to increase the
acceleration time, and CCW to decrease the acceleration time.
