Signal
—
Set the target position with parameter. (Pr. 133)
Terminal 1 Input dancer roll position detection signal.
Terminal
Set the main speed which becomes the line speed.
2, etc.
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.
Turn ON X30 signal to reset integral term.
OFF: Does not reset integral term.
X30
ON: Resets integral term.
Integral term can be reset with MRS signal input when terminal is not assigned.
Turn ON X32 signal to reset differential term.
X32
OFF: Does not reset differential term.
ON: Resets differential term.
X33
Set an analog value, which is input to terminal 1, to Pr. 751 as offset.
Turn X34 signal ON/OFF to enable/disable the control by integral term.
OFF: Disables integral term.
X34
ON: Enables integral term.
Integral term is enabled when X34 signal is not assigned.
Turn ON to select compensation by main rotation speed command.
OFF: Speed compensation gain does not change regardless of main speed.
X35
ON: Speed compensation gain changes with main speed.
Speed compensation gain changes with main speed when X35 signal is
not assigned.
X51
Acceleration/deceleration time of main speed can be switched.
X52
X53
Select minimum/maximum winding diameter.
X54
X55
Clears stored winding diameter calculation results.
X56
Select whether winding or unwinding shaft.
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,
X83
wait 20ms or longer to input a start command (STF/STR).
