DOX: (DOX+, DOX-)
X = 1, 2, 3, 4, 5, 6
DO1: (7, 6)
DO2: (5, 4)
DO3: (3, 2)
DO4: (1, 26)
DO5: (28, 27)
DO6: (40, 46)
Note:
Refer to Chapter 3 Wiring.
1.
The brake signal controls the solenoid valve, providing power to the brake and enabling the brake.
2.
Please note that 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 =
2-24
Servo drive
Ensure the polarity of
diode is correct, or it
will damage the drive.
