FA-00 and FA-01 set input channel of PID reference. PID reference is a relative value and
ranges from 0.0% to 100.0%.
FA-02 sets PID feedback channel. PID feedback is a relative value and ranges from 0.0%
to 100.0%.
FA-03 sets direction of PID operation. It is inuenced by DI function 35 "PID operation
direction reverse".
● FA-03 = 0: Forward
When PID feedback is smaller than PID reference, the AC drive increases output
frequency. The winding tension control requires forward PID operation.
● FA-03 = 1: Reverse
When PID feedback is smaller than PID reference, the AC drive decreases output
frequency. The unwinding tension control requires reverse PID operation.
FA-04: It is a non-dimensional parameter and is used for calculating display of PID
reference (U0-15) and PID feedback (U0-16).
● U0-15 = PID reference (percentage) x FA-04
● U0-16 = PID feedback (percentage) x FA-04
For example, if FA-04 is set to 2000 and PID reference is 100.0%, display of PID
reference (U0-15) is 2000.
