3.3.3 Manually releasing the brakes
Introduction to manually releasing the brakes
This section describes how to release the holding brakes for the axes motors using
the FlexPendant.
To fulfill ISO 10218-1:2011 5.13 Movement without drive power, a FlexPendant
must be available on the site when using RobotWare 7.10 and higher.
CAUTION
On robots with RobotWare earlier than 7.10, the brakes are released using an
external brake release tool, see
Manually releasing the brakes with the external
tool on page 71 .
DANGER
If there is no FlexPendant connected, or in a system failure state, the brake
release function is not immediately available. Dangerous clamping situations
should always be mitigated using safety functions, see the section
Configuring
the software on page 114 .
CAUTION
At least two persons should be present when releasing the brakes.
