Control method

1) The method of controlling the pressing operation is the same as that described in (1)

Positioning except the setting of the position table. Any setting of “Pressing” in the position

table allows the pressing operation to be done. “Positioning width” is assumed as pressing

operation distance.

2) The actuator moves at the setting speed and rating torque to the position of the coordinate

set in “Position” in the similar way as normal positioning. The operation is executed with the

value set in “Positioning width” for the amount of movement in the pressing operation, and

the torque (current limit) set in % in “Pressing” for the pressing operation as the upper limit.

Ԛ

Current Position No. PE* is output when the axis stops by pressing operation (pressing

complete). Also, even when not pressing a work piece (pressing error), a movement is

made for the setting of “positioning width”, and then turns ON.
