PID Control Type
The inverter offers two types of PID control:
(a) PID control with differential feedback: (10-03 = x1xxb)
Make sure to adjust the PID parameters without causing system instability. Refer to Figure 4.4.78 for PID control
for feedback value differential.
Figure 4.4.78 PID control for feedback differential value
(b) Basic PID control:
(10-03 = x0xxb)
This is the basic type of PID control. Refer to the figure 4.4.79.

PID Setup
Enable PID control by setting parameter 10-03, PID target value (10-00) and PID feedback value (10-01).
To use PID control set frequency command selection 00-05 to 4.
