Tension sensor feedback torque control
details
The tension sensorless torque control is performed to control the output torque of a motor according to the roll diameter so
that the tension applied to a material is constant. Using the feedback from tension sensors allows winding/unwinding for a
high-quality finish.
This section explains the details unique to the tension sensor feedback torque control. Common information among torque
control is stated in 5.5 (Tension sensorless torque control details).
POINT POINT
• Select torque control under Vector control or Real sensorless vector control to perform tension sensor feedback torque
control.
• Turn the X114 signal ON to perform tension sensor feedback torque control. When the X114 signal is OFF, the tension sensor
feedback torque control is not available.
