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.
