Tension Sensor Feedback Torque Control Details - Mitsubishi Electric A800 Plus Series Function Manual

6.5
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).
Purpose
To select forward/reverse action for
PID control
To select winding or unwinding for a
shaft
To input the tension feedback to the
inverter
To detect tension feedback
malposition
To allow a signal to be output during
normal tension feedback
To enable manual input of gains for
PID control
To perform setting for tension
sensorless torque control
To select the tension command
input method
To select the tension command
setting increment
To select the torque generation
direction
To prevent the roll from getting too
tight when the winding diameter
increases
To keep the tension applied to the
material constant also during
acceleration/deceleration
To prevent tension change due to
factors such as mechanical friction
To prevent sagging of the material
before starting winding
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.
