Wiring Example
Use the servo amplifier output signal /BK and the brake power supply to form a
brake ON/OFF circuit. The following diagram shows a standard wiring example.
Figure 5.8 Wiring Example
This output signal controls the brake when using a servomotor with a brake and does
not have to be connected when using a servomotor without a brake.
The following parameter is used to set the state of /BK output.
