3.8 I/O Signal Controls and Function
155
(15) Brake release (BKRL) PLC Output Signal
Turning this signal “ON” can release the brake forcibly.
(16) Push-motion specification (PUSH) PLC Output Signal
When the movement command signal is output after this signal is turned ON, the pressing
operation is performed.
When this signal is set to “OFF”, the normal positioning operation is performed.
In Direct Indication Mode, the same pressing type as CON related models such as PCON
Controller or the same pressing type as SEP related models such as PSEP can be selected for
the pressing type in Gateway Parameter Setting Tool.
[Pressing Operation CON Method]
After reaching the target position (Note 1) from the current position, the actuator moves with the
pressing speed for the distance set as the pressing band width.
The positioning complete signal (PEND) turns ON if the work piece hits and pressing is
judged as completed while in the pressing operation.
(Note 1) In Direct Indication Mode, it is the value input in the target position register.

[Pressing Operation SEP Method]
The pressing operation is performed with the start position set at the point in front of the
target position (Note 1) for the width of the positioning width (for Direct Indication Mode), or the
point set in the pressing width (for Simple Direct/Positioner 1 Modes).
The positioning complete signal (PEND) turns ON if the work piece hits and pressing is
judged as completed while in the pressing operation.
(Note 1) The value is that set as the position in the position data for Positioner 1 Mode, and
that input in the target position register for Simple Direct and Direct Indication
Modes.
