Using an external voltage supply directly on the respective brake
This procedure details how to release the holding brake of a specific axis by
supplying external voltage directly on the brake.
NoteAction
Make the connection to the current motor
according to the Circuit Diagram.
Every axis has a holding brake built into the
axis motor. This holding brake may be re-
leased by connecting 24VDC power supply
directly to one of the connectors in the motor.
DANGER
When power is connected directly to the
brake cable, the brake will be released imme-
diately when the power is switched on.
This may cause some unexpected robot
movements!

Connect an external 24 VDC power supply
to the motor, according to the figures.
Note
Be careful not to interchange the 24V and 0V
pins!
If they are mixed up, damage can be caused
to the intergrated quenching circuits.
WARNING
Incorrect connections can cause all brakes
to be released simultaneously!
