(Note) *ALM Signal is an active low signal. It is ON when the power is applied to the controller, and
turns OFF when the signal is output.
[10] Brake Forcible Release (BKRL)
Output
PIO signal
BKRL
The brake can be released while BKRL signal is turned ON.
For the actuator equipped with a brake, the brake can be controlled by turning the servo
ON/OFF, however, a release of the brake may be necessary in the case of installing the unit to
a system so the slider or rod can be moved by hand.
This operation can be performed not only by the brake release switch on the front panel of the
controller, but also by the brake release signal BKRL.
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.
(4) It is prohibited to switch over between AUTO and MANU while this signal
is ON (brake is released).
