[5] Tension Operation
Warning: Do not perform tension operation by pressing operation using force sensor.
The pressing operation using force sensor requires an actuator applicable
for dedicated loadcell and pressing operation using force sensor.
The tension operation by using an actuation equipped with loadcell causes
the loadcell to be damaged.

Control method
The method of controlling the tension operation is the same as that described in [4] Pressing
operation. The control method is explained below by using the sample position table shown
above.
1) Position No.2 indicates the settings of tension operation. The settings of “Position” and
“Positioning width” show the tension start position and the tension quantity, respectively.
Attach – (minus sign) to the tension quantity. Specify the upper limit of the torque required
for tension in percent (limited current value) in “Pressing”. The speed, acceleration, and
deceleration are the conditions of positioning to the coordinate value (80mm) set in
“Position”.
2) Position No.1 indicates the tension start preparation position. Specify a value larger than
the coordinate value at which the tension provided by position No.2 ends (80 – 50 = 30mm)
in “Position”.
3) First define the positioning in position No.1. Next, the operation in position No.2 moves the
actuator to the position of 80mm at the setting speed and rating torque and change to the
tension operation. The actuator moves by 50mm in the negative direction in the tension
operation. The upper limit of the tensile force is the torque set in percent.
