DOX+
DO1 ： (7,6)
DO2 ： (5,4)
DO3 ： (3,2)
DO4
：
(1,26)
DO5 ： (28,27)
DO6 ： (40,46)
DOX ： (DOX+,DOX-)
X=1,2,3,4,5,6
Ensure the polarity of
diode is correct, or it
will damage the drive

For brake
It is open circuit when the
emergency stop signal is on.

Note:
1.
Please refer to Chapter 3 Wiring.
2.
The brake signal controls the solenoid valve, providing power to the brake and enabling the brake.
3.
Please note that there is no polarity for the coil brake.

Calculating 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 Motor specifications),
so the brake’s rated current =
6 . 5 W
24V
= 0.27 A
