Caution
When the motor load is a slide with limited travel,
avoid the slide activating the limit switches by
increasing the reference signal frequency or decreasing
the reference signal amplitude in order to reduce the
speed.
Note
The minimum acceptable amplitude for the reference
signal is 1V peak-to-peak.
9. Apply power to the Drive.
10. Enable the Drive.
11. The waveform could be as shown in Figure 18. In
this case, the system has insufficient dynamic
gain. Turn the
PROPORTIONAL potentiometer.

12. When a waveform without oscillation has been
obtained, in most cases the response will have an
overshoot as shown in Figure 19. In this case, the
system has insufficient derivative action. Turn
the
DERIVATIVE potentiometer clockwise to
eliminate the overshoot as shown in Figure 20.
