Brake Signal Circuit Diagram
The brake connection of the input signal without polarity, but it needs users to prepare a 24V
power supply. An example of the standard connection between the brake signal BK and the 24V
power supply is shown below:

4.5 CN2 Encoder Signal Terminal
4.5.1 CN2A Signal Introduction
The encoder signal connector CN2 connects with the servo motor encoder. A 15 pins plug is used.
◆
The brake mechanism built into the servo motor is a fixed special mechanism
of non-electric action type, which can not be used for braking purposes. Only when
the servo motor is kept in a stop state can it work.
◆
The brake coil has no polarity.
◆
After the servo motor stops, the servo signal (Servo On) should be cut off.
◆
When the motor with the built-in brake is running, the brake may make a
“click” sound, which has no effect on its function.
When the brake coil is electrified (open state of the brake), flux leakage may occur
at the shaft end and other parts. Therefore the nearby devices might be interfered..
◆
It is forbidden to share the power supply with other electrical appliances,
which is to prevent the voltage or current from decreasing resulting to the wrong
work due to other electrical appliances
.

Above 0.5 mm

cable is recommended.
