Caution: (1) The speed during pressing operation is set in Parameter No.34. Check the
9.4 List of Specifications of Connectable Actuators for the pressing
operation speed.
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 pressing speed, the pressing is
performed at the setup speed.
(2) The approach start position of pressing should be located at or before the
pressing start position (coordinate 100mm or less in the above example) If
not, the moving direction varies depending on the start position to be
dangerous.
For example, pressing at coordinate larger than the pressing end position
(larger than 150mm) is performed in the direction from the current position
to the pressing end position. Note that pressing after positioning to the
position of coordinate 100mm does not take place.
(3) The work is pressed after the pressing is completed. The work may moves
backward or forward. If the actuator is moved backward before the
approach position, alarm code 0DC “Pressing motion range over error”
occurs to stop the actuator. In movement of the work in the pressing
direction, PEND is turned OFF if the load current becomes lower than the
current limit (pressing (%)). Miss-pressing occurs when the actuator moves
by the pressing moving distance set in “Positioning width”.
(4) Do not make control of changing to pressing on the way of normal
positioning (before PEND turning ON). Depending on the position at which
start signal CSTR is turned ON, the pressing is performed improperly. Then
the PLC cannot manage the position of the actuator.
(5) Pressing control cannot be performed with the rotary actuator. If the index
mode is selected for the rotary actuator of multi-rotation specification,
pressing operation cannot be set. The positioning complete signal PEND is
turned ON when the actuator reaches the positioning width.
(6) If the actuator gets pressed to the work during the approach operation, 0DC
“Pressing Operation Range Over Error” would be issued.
