Brake release (BKRL)
When the actuator is equipped with a brake, you may want to forcibly release the brake in certain
situations such as when starting up the system for the first time. Normally the brake release switch on the
front panel of the controller is set to the “RLS” side to release the brake. For added convenience, the
brake can now be released from the PLC.
If this signal is ON while the servo is off, the brake is released.
Use this signal to provide a release switch near the actuator when the actuator is located away from the
controller.
Operation mode (MODE)
This signal is effective when the teaching type is selected.
When this signal is turned ON while the actuator is standing still, the normal operation mode will change to
the teaching mode.
The controller will turn ON the MODES output signal upon receiving this signal.
Program the PLC so that it will accept a current-position write command after confirming that the MODES
output signal is ON.
When this signal is turned OFF, the controller will return to the normal operation mode.
Current-position write (PWRT)
This signal is enabled when the aforementioned MODES output signal is ON.
When this signal has remained ON for 20 msec or longer, the controller will read the position number
specified by a binary code consisting of PC1 through PC32 as currently detected, and write the current
position data in the “Position” field of the corresponding position number.
If data of other items (speed, acceleration/deceleration, positioning band, etc.) are yet to be defined, the
default settings of the corresponding parameters will be written.
When the writing completes successfully, the WEND output signal will turn ON.
Configure the system in such a way that the PLC will turn OFF the PWRT signal when WEND turns ON.
The controller will turn OFF WEND once the PWRT signal turns OFF.
(Note) An alarm will generate if a write command is issued when home return has not been performed
yet or while the actuator is moving.
Manual operation switching (JISL)
This signal is enabled when the teaching type is selected.
The JISL signal is used to switch operations in the manual mode. Specifically, the actuator will jog when
this signal is OFF, or inch when this signal is ON.
If this signal is turned ON while the actuator is jogging, the actuator will decelerate to a stop.
If this signal is turned OFF while the actuator is inching, the actuator will continue with its inching
movement.
