Installation
When the motor runs normally (Servo On), DO.BRKR should be set to On, it means the brake is
operating and the motor can run freely. Use the emergency stop button in an emergency. Press
the button to switch the motor to Off and set DI.EMGS (0x21) to On. Then AL013 is triggered,

and the motor is immediately stopped.
Wiring of the brake:
Note:
Refer to Chapter 3 Wiring.
1.
The brake signal controls the solenoid valve, providing power to the brake and enabling the brake.
2.
There is no polarity for the brake coil.

Calculate the brake's rated current (ECM-A3L-CY0604RS1 is used as an example here).
Power consumption of the brake (20°C) = 6.5 W (refer to Appendix A Specifications), so the
brake's rated current =
2-34

Ensure the polarity of
diode is correct, or it
will damage the drive.
