Figure 4-3 Waveform resulting from insufficient proportional gain
11. The waveform could be as shown in Figure 4-3. In this case, the system has
insufficient dynamic gain. Turn the PROPORTIONAL potentiometer clockwise to
obtain a waveform without oscillation.
12. When a waveform without oscillation has been obtained, in most cases the
response will have an overshoot as shown in Figure 4-4. In this case, the system
has insufficient derivative action. Turn the DERIVATIVE potentiometer clockwise to
eliminate the overshoot, as shown in Figure 4-5.
