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. Then the operation changes to

pressing. The moving distance in pressing is the value set in “Positioning width”. The

pressing is performed with the torque (current limit value) set in percent in “Pressing” of PIO

patterns 1 to 2 being the upper limit.

3) The control method is the same as that in [1] Positioning. However, the processing of

positioning complete signal PEND is different from that in [1] Positioning.

PEND is output when the shaft is stopped by pressing (pressing complete). If the work is not

subject to pressing (miss-pressing), the actuator moves by the value set in “Positioning

width” to stop but PEND is not turned ON.
