X83
Enables/disables the tension control and the winding diameter compensation function.
OFF: Normal operation.
ON: Tension control and winding diameter compensation are valid.
When the X83 signal is not assigned, normal operation is performed.
To use the tension control and the winding diameter compensation
function, make sure to assign this signal.
Turn ON/OFF the X83 in a stop status to switch between the tension control and
normal operation. After turning ON the X83 signal, wait 20ms or longer to input a
start command (STF/STR).
