Dancer roll position detection
Terminal 1 Input dancer roll position detection signal.
Main speed setting
Terminal
2, etc.
Set the main speed which becomes the line speed.
Line speed detection
—
Input detection signal of line speed. Input method can be selected from below.
Same as the main speed.
Pulse train input
(single-phase pulse from terminal JOG and FR-A7AL, encoder pulse* from
FR-A7AP/FR-A7AL)
Analog input (terminal 2, terminal 4)
* Encoder pulse train inputs are not available during vector control.

PID integral term reset
input
X30
Turn ON X30 signal to reset integral term.
OFF: Does not reset integral term.
ON: Resets integral term.
Integral term can be reset with MRS signal input when terminal is not assigned.

32
PID differential term
reset input
X32
Turn ON X32 signal to reset differential term.
OFF: Does not reset differential term.
ON: Resets differential term.

34
Integral term activation
signal
X34
Turn X34 signal ON/OFF to enable/disable the control by integral term.
OFF: Disables integral term.
ON: Enables integral term.
Integral term is enabled when X34 signal is not assigned.

Speed compensation
gain
selection
X35
Turn ON to select compensation by main rotation speed command.
OFF: Speed compensation gain does not change regardless of main speed.
ON: Speed compensation gain changes with main speed.
Speed compensation gain changes with main speed when X35 signal is
not assigned.

56
Winding/unwinding
selection
X56
Select whether winding or unwinding shaft.
83
Dancer/tension control
function selection
X83
Select dancer control and winding diameter compensation function.
OFF: Normal operation.
ON: Activates dancer control and winding diameter compensation function.
Normal operation is performed when X83 signal is not assigned.
Always set when using dancer control and winding diameter
compensation function.
Turn ON/OFF the X83 in a stop status to switch between the dancer
control operation and normal operation. After turning ON the X83 signal,
wait 20ms or longer to input a start command (STF/STR).
