[Dancer control operation]
1) Inverter operates by speed reference.
*Dancer control use override addition function for speed reference.
2) PID control: Process value; dancer position
Feedback value; dancer detection value
Correct speed reference by deviation of PID control for dancer.
Set the dead band (f379) for the deviation if necessary.
3) Set the dancer correction OFF signal to input terminal if necessary.
In case the input terminal ON, the PID output is zero. The speed reference is override addition value.
Windup: If the value after override addition become following, inverter control stop the integration.
(1) Upper limit (ul) or more
Maximum frequency (fh) or more
(2) Lower limit (ll) or less
Clear the windup process by deviation value of PID control.
[Parameter setting]
See the chapter 4 and 5 for detail of parameter setting.
1) Select the PID control type.

2) Set the speed reference as override addition.
Item
Addition
*You can set override multiplication (f661) instead of f660, but it is difficult to set.
Use f660 please.
3) Select the input of process value (dancer position) and feedback value (dancer detection value).
Set each level converted into frequency for the setting.
Set the dead band for deviation of PID control if necessary.
