The brake can be released while BKRL signal is set to ON. If a brake is installed in the actuator,
the brake is automatically controlled by servo ON/OFF. Releasing the brake may be required to
move the slider and/or the rod by hand in case of installation of the actuator in the machine or
direct teach *1 . This operation can be performed not only by the brake release switch on the
front panel of the PIO converter, but also by the brake release signal BKRL.
*1 Direct teach : This operation is intended to get coordinate values to the position by moving
the slider and/or the rod by hand.
Warning: (1) Take sufficient care to release the brake. Inappropriate brake release
may cause people to be injured and/or the actuator, the work and/or the
machine to be damaged.
(2) After the brake is released, always make the brake applied again. Any
operation with the brake remaining released is extremely dangerous. The
slider or rod may drop to cause people to be injured and/or the actuator,
the work and/or the machine to be damaged.
(3) Make certain that this signal is turned OFF (brake is activated) when the
power is supplied to the controller.
