1.3 Robot stopping functions
Protective stop and emergency stop
The protective stops and emergency stops are described in the product manual
for the controller.

Reasons for selection of emergency stop category in IRB 1300-12/1.4
The emergency stop shall function either as a category 0 stop or as a category 1
stop. The selection of the emergency stop category depends on the risk assessment
results of the robot.
For emergency stop in IRB 1300-12/1.4, a category 1 stop is defined as default.
Exceptions are only allowed when there is a technical fault in the system.
Category 1 emergency stop is used otherwise because:
•
Stopping using the motor produces repeatable stopping distances (no
variation of brake friction coefficient).
•
Stopping using the motor produces the shortest stopping distance without
any risk of overloading structural components (pre-defined braking torque,
no delay), and, minimizes the forces applied by robot.
•
Stopping using the motor saves on brake wear, so that the brake can perform
its primary (holding) function for longer.
Because of these reasons, the end user/system integrator should always use a
category 1 emergency stop for IRB 1300-12/1.4 in the application risk assessment,
with category 0 emergency stop still being configurable in settings of external/local
emergency stop.
