Release with switch
Press and hold the mode change switch on the front panel toward the "BRK OFF" side (for more
than 2 seconds), the brake will be released and the "BRK OFF" LED will light.
While releasing the brake, press and hold the mode change switch on the front panel toward the
"BRK OFF" side (for less than 0.5 seconds), the brake will be enabled and the "BRK OFF" LED
will be turned off.
WARNING
Note that if the brake is released
when using it in the vertical direc-
tion, the moving part may fall freely.
So be sure to do this after securing
the moving part.
Failure to do so may cause damage or
injury.
Note that if the mode change
switch is turned AUTO with BKRL
input (pin.12) of external input and
output ON, the moving part may fall
freely. So be sure to turn the BKRL
input (pin.12) OFF and then set the
mode change switch to AUTO.
Failure to do so may cause damage or
injury.
If it is manually released, return it
to the valid status manually. The
brake remains released until it is
returned to the valid status, and it
does not interlock with the servo
ON/OFF. Also, note that if the brake
is stopped with the emergency
stop switch, it is released when the
switch is back.
Obligatory
The brake of the actuator with brake can be released manually.
Normally it is interlocked with servo ON for brake release.
However, if it will not interlock if deactivated manually (by using switches or external
input and output), and it remains deactivated even if the servo is turned OFF. In this
case, it must be manually returned to the valid status.
