Safeguard

Safety barriers for safety must be installed around the Manipulator, and safeguards must be installed at the entrance and exit of the safety barriers.

The term "safeguard" mentioned in this manual is a safety device with an interlock that allows entry into the safety barriers. Safeguards include safety door switch, safety barriers, light curtains, safety gates, safety floor mats, and so on. The safeguard is an input that informs the Robot Controller that an operator may be inside the safeguard area.

For RC700-E, RC800-A:

You need to assign at least one Safeguard (SG) in Safety Function Manager. For more details, refer to the following manual:
