Signal name
Turn ON the X114 signal to enable the dancer feedback speed
control, tension feedback speed control, tension sensorless
torque control, tension sensor feedback torque control, and
winding diameter compensation functions. If the signal is OFF,
normal speed control is applied.
Always set the signal for using the dancer feedback speed
control, tension feedback speed control, tension sensorless
torque control, tension sensor feedback torque control, and
winding diameter compensation functions. (When the X114
signal is not assigned to any input terminal, general speed
X114 control or torque control is enabled.)
Turn ON/OFF the X114 signal in a stop status to switch between
each control operation and normal operation.
After turning ON the X114 signal, wait 20 ms or longer to input a
start command (STF/STR).
Turn ON the X115 signal to keep the present winding diameter.
X115
(The winding diameter compensation is disabled.)
Turning ON the X116 signal interrupts the PID control under
dancer feedback speed control, tension sensor feedback speed
X116 control, or tension sensor feedback torque control. (The PID
compensation amount, integral term, and differential term are
cleared.)
X117 Clears the measured winding/unwinding length.
Switches the PID gain.
Turning ON the X122 signal enables the initial winding
X122
measurement mode.
X123 Turning ON the X123 signal triggers the stall mode.
Disables the settings of Pr.641 to Pr.644 (Speed control
X124
proportional gain).
Enables write and read of the line speed command value
through communication during dancer / tension sensor feedback
speed control, regardless of whether the dancer / tension sensor
feedback speed control is valid or invalid.
X125
Enables write and read of the tension command value through
communication during tension sensorless torque control,
regardless of whether the tension sensorless torque control is
valid or invalid.
Switches between winding and unwinding during operation. The
X126
dancer roll position can be held during switching.
