Table 6-76 PID Select Menu (4350) Parameters
Parameter ID Unit Default Min Max Description
Prop gain 4360 0.39 0.0 98.996 Set the PID loop "Proportional (P) gain".
Integral gain 4370 0.39 0.0 98.996 Set the PID loop "Integral (I) gain".
Di gain 4380 0.0 0.0 98.996 Set the PID loop "Derivative (D) gain".
Min clamp 4390 % 0.0 -200.0 200.0 Set the minimum value for the PID loop integrator.
Max clamp 4400 % 100.0 -200.0 200.0 Set the maximum value for the PID loop integrator.
Setpoint 4410 % 0.0 -200.0 200.0 Set a value to be used as the reference setpoint for the
external PID loop. The value is set as a percent of full
scale. This parameter can be used instead of Analog
Input #1 (4100) for reference in the PID loop.
Using a PID controller for speed reference
When using an external PID controller as the speed reference, analog input 1 (4100) or the set
point (4410) are used for PID command, and analog input 2 is used for PID feedback.
The input is pre-selected via the SOP.
See Tables Analog Input #1 Menu (4100) and Analog Input #2 Menu (4170) for scaling
information.
CAUTION
Providing correct inputs and parameters for PID command and feedback
If you assign incorrect inputs for PID command and feedback, it may cause instability of the
system and severe mechanical damage.
You are responsible for providing correct inputs and parameters for PID command and
feedback.
Check that all inputs and parameters for PID command and feedback are correctly assigned.
