Caution: (1) The speed during tension operation is set in Parameter No.34. Check the
9.1 List of Specifications of Connectable Actuators for the pressing speed.
The speed for pulling operation is same as that for pressing operation.
Do not set any value larger than the value in the list. If the speed set in the
position table is equal to or less than the tension speed, the tension
operation is performed at the setup speed.
(2) The tension ready position should be the tension start position or forward. If
not, the moving direction varies depending on the start position to be
dangerous.
The tension operation from a coordinate (less than 30mm = 80 – 50 in the
above example) located before the end position (30mm or less) changes to
the pressing operation from the current position to the tension end position.
Note that the tension operation after positioning to the position of 80mm
does not take place.
(3) The work is pulled also after completion of the tension. The work is drawn
back or pulled further if the work is moved. When the work is drawn back
before the approach position, alarm code 0DC “pressing operation range
error” occurs to stop the work. When the work is moved in the tension
direction and the load current becomes less than the current limit value
(pressing in [%]), PEND is turned OFF. Naturally, the work reaches the
tension moving distance set in “Positioning width” to cause miss-pressing.
(4) Do not make control of changing to tension operation on the way of normal
positioning (before PEND turning ON). Depending on the position at which
start signal is turned ON, the tension operation is performed improperly.
Then the PLC cannot manage the position of the actuator.
(5) Tension operation cannot be performed with the rotary actuator.
