3.7.3 Adjustment of target position input (Pr. 708, C3, C4, C6, C7, C13, C15, C31, C33)
* The parameter number in parentheses is the one for use with the parameter unit (FR-PU04/FR-PU07).
Position signal from dancer roll can be filtered by setting Pr. 708 .
Set the time constant of the first-order lag filter. Set a large time constant when you want to delay the tracking of the speed
command, when the analog input voltage fluctuates, etc.
Above parameters can also be used to calibrate the signal of each terminal.
3.7.4 Measured value upper/lower limit detection signal (Pr. 131, Pr. 132)
When the measured value exceeds PID upper limit (Pr. 131) , PID upper limit (FUP) signal is output. Likewise, when
measured value falls below PID lower limit (Pr. 132) , PID lower limit (FDN) signal is output. Set each limit in parameter.
For output signals, assign "14, 114 (FDN)" or "5, 115 (FUP)" to any of Pr. 190 to 196 (output terminal function selection) .
3.7.5 PID gain switchover (Pr. 138, Pr. 270 to Pr. 278, Pr. 464 to Pr. 481, X89 signal, X90 signal)
(1) Second to fourth PID gain switchover
PID gain can be switched by ON/OFF of X89 signal and X90 signal.
Set "89(X89)" and "90(X90)" in
Pr. 178 to 189 (input terminal function selection)
to assign X89 and X90 signals.
