PID Setup
Trim Control
In Trim Control, the PID Output is added to the Speed Reference. In
Trim mode, the output of the PID loop bypasses the accel/decel ramp
as shown. Trim Control is used when Parameter 232 (PID Ref Sel) is
set to option 5, 6, 7, or 8.
Example
•
In a winder application, the PID Reference equals the
Equilibrium set point.
•
The Dancer Pot signal provides PID Feedback to the drive.
Fluctuations in tension result in a PID Error value.
•
The Master Speed Reference sets the wind/unwind speed.
•
As tension increases or decreases during winding, the Speed
Reference is trimmed to compensate. Tension is maintained near
the Equilibrium set point.
