4) Brake release switch (each axis of 1 to 4)
It is the switch to release the brake compulsorily (excitation release) for the actuator
equipped with a brake. When it is desired to move an actuator manually in such cases as
to set up the equipment, in teaching and in an error, the brake can be compulsorily
released by putting the switch to RLS side after turning the power on.
Keep the switch set on NOM side unless necessary.
Switch position Function
RLS (Brake release) Top side Brake is released compulsorily.
NOM (Automatic
mode)
Bottom
side
Brake gets controlled automatically by
controller.
Servo ON : Brake release
Servo OFF : Brake effective
Warning : After conducting the brake compulsory release, make sure to set the
switch back to NOM (automatic mode) so the controller can perform the
automatic control on the brake. In RLS (brake release), it is very
dangerous as the brake would not work when emergency stop is occurred
or servo is turned OFF. For vertically mounted actuators, the slider or rod
can drop and it may cause a critical accident.
