„ Control method
The method of controlling the tension operation is the same as that described in [3] 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 – (negative 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”.
