ABB IRB 120 User Manual

2.3.2 Manually releasing the brakes
Introduction to manually releasing the brakes
This section describes how to release the holding brakes for the motors of each
axis.
This can be done in three ways:
• using the brake release unit (placed on the front of the IRC5 Compact
controller) when the robot is connected to the controller. For other controller
variants, the placing depends on the design of the cell.
• using the brake release unit when the robot is disconnected from the
controller, but connected to an external power supply at the connector R1.MP.
• using an external voltage supply directly on the motor connector.
Note
On the single controller there is no brake release button. The customer or
integrator is responsible to ensure that it in case of emergency is possible to
release the brakes to move the manipulator axes without using motion power.
