6.4. EMERGENCY STOP
When the emergency stop button is pressed, the power is removed from the arm and the brakes are applied. The
other equipment in the cell is also cut off from the power supply (depending on the cell wiring).
Following an emergency stop, a specific procedure is required to restore power to the arm:
• The operator must leave the danger zone.
• The MCP must be resting on its holder, fixed permanently outside the cell (a contact inside the MCP enables
this operation to be checked).
Restarting
Once those concerned have made certain that safety conditions have been restored, the arm power procedure
can be carried out using the MCP.
Note:
This operation must be carried out with the MCP on its holder when in manual mode.
• Release the emergency stop button by turning it clockwise 1/4 turn.
• Restore power to the arm in accordance with the standard procedure, using the arm power button on the MCP.
CAUTION:
The emergency stop is not the normal method for stopping arm movements; it must only be
used in a case of absolute necessity for a stop not provided for in your application.
An emergency stop leads to a sudden cut-off of power to the arm (and other equipements in
the cell), which, if it is repeated too often, leads to damage and reduced motor service life.
DANGER:
When the robot is restarted, all persons are prohibited from remaining in the isolation
area in which the arm moves.
DANGER:
If the MCP is not connected to the controller, it must not be left near the cell, because
its emergency stop button no longer works.
