4.4.4 Wiring of Servo Drive and Brake
Important
When using a motor with a brake, please select a surge absorber according to the brake current and power
supply used.
Please confirm the brake action time through the user equipment after connect the surge absorber.
The brake action time will vary depending on the type of surge absorber.
Please form a relay circuit to enable the brake to operate in case of emergency stop.
The brake control output (/BK) signal can change the distribution of the output signal.
When using the 24V brake, the DC 24V power supply must be separated from the input and output signals
(CN1) and other power supplies separately.
Common power s
upply will lead to misoperation of input and output signals.
