Signal
X57 Compensates the inertia during acceleration.
X58 Compensates the inertia during deceleration.
X59 Switches the inertia compensation acceleration/deceleration time.
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
X83
start command (STF/STR).
X91 Turn the X91 signal ON to select the winding diameter measurement mode.
X92 Turn the X92 signal ON to bring the motor into the stall status.
Signal
Y51 Output when winding diameter calculation is completed at an operation start.
