3. Parameter Description
20-96 PID Diff. Gain Limit
Range:
*
5.0 [1.0 - 50.0]

164
Function:
The differentiator of a PID Controller responds to the rate of change of the feedback. As a result, an abrupt
change in the feedback can cause the differentiator to make a very large change in the PID Controller's output.
This parameter limits the maximum effect that the PID Controller's differentiator can produce. A smaller value
reduces the maximum effect of the PID Controller's differentiator.
This parameter is only active when par. 20-95 is not set to OFF (0 s).
