This section details how to release the holding brakes with the internal brake release unit

using an external voltage supply. This is done if the robot is not connected to the controller.

Action Note/Illustration

DANGER!

Incorrect connections, such as supplying

power to the wrong pin, may cause all brakes

to be released simultaneously!

Also, be careful not to interchange the

24V and 0V pins. If they are mixed up,

damage can be caused to a resistor

diode and to the system board.

2. Connect an external power supply to

connector R1.MP.

Supply:

• 0V on pin C10

• 24V on pin B8.
