Operation
(1) Wiring Example
Use the SERVOPACK contact output signal /BK and the brake power supply to form a brake ON/OFF circuit.
The following diagram shows a standard wiring example.
(2) Brake Interlock Output
(3) Allocating Brake Signals (/BK)
The brake signal (/BK) is not used with the factory settings. The output signal must be allocated.

Setting Meaning
Output /BK Must be allocated ON (low level) Releases the brake.
OFF (high level) Applies the brake.
This output signal controls the brake and is used only for a servomotor with a brake. This output signal is not used with the
factory settings. The output signal must be allocated (with Pn50F). It does not need to be connected for servomotors with-
out a brake.
 IMPORTANT
The /BK signal is not output during overtravel, or when there is no power to the servomotor.

 IMPORTANT
When set to the factory setting, the brake signal is invalid. When multiple signals are allocated to the same output termi-
nal, the signals are output with OR logic. To output the /BK signal alone, disable the other output signals or set them to
output terminals other than the one allocated to the /BK signal. For the allocation of SERVOPACK output signals other
than /BK signal, refer to 7.3.3 Output Circuit Signal Allocation.
