Notes:
• The above settings are for Ext1 control location. Accordingly, you can set for Ext2
control location.
• The examples provided in this chapter are based on PID set 1. You can set the
desired values for PID trim function's parameters to get the expected result.
The following modes are available:
•
•
, and
•
Direct
The direct method is suitable where you need tension control at fixed rpm/line speed.
In this mode, the PID trimmed output (
) is relative to
), torque (
) or frequency (
). The selection between these can
be made by parameter
The calculated trimmed output is same throughout the speed range with respect to
the stable PID output.
