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 4 being the upper limit.
Pressing operation using force sensor of PIO pattern 7 performs pressing by the pressing
force set in percent of the base thrust in pressing operation using force sensor
*1
.
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. The current position No. PE* is
turned ON at the completion of pressing and even in miss-pressing.
