1.7 Safety Features

The robot control system supports safety features described below. However, the
user is recommended to strictly follow the proper usage of the robot system by
thoroughly reading the attached manuals before using the system. Failure to read
and understand the proper usage of the safety functions is highly dangerous.
Among the following safety features, the Emergency Stop Switch and Safety Door
Input are particularly important. Make sure that these and other features function
properly before operating the robot system.
For details, refer to the 2.5 Controller Installation - Safety Door Switch and Latch
Release Switch.
ATTEND (TEACH) Control Device
To operate the Manipulator at a short distance without any operation unit (option),
you must create an ATTEND (TEACH) control device and connect it to the
OPTIONAL DEVICE connector on the front of the Control Unit in order to
operate the Manipulator at a short distance. The ATTEND (TEACH) control
device should consist of the Emergency Stop switch, 3-position enable switch
(dead-man switch), and ATTEND (TEACH) control device enable/disable switch.
The name of the control device depends on the software used in your Control Unit
as shown below:

Emergency Stop Switch
The ATTEND (TEACH) control device must be equipped with the Emergency
Stop switch. The EMERGENCY connector on the Drive Unit has extension
Emergency Stop input terminals used for connecting the Emergency Stop switches.
These Emergency Stop inputs are internally connected to the relays for the
dynamic brake. Therefore, pressing any Emergency Stop switch can shut off the
motor power immediately and the robot system will enter the Emergency Stop
condition.
