20 EPSON RC+ 5.0 (Ver.5.4) User's Guide Rev.4
2.5 Precautions regarding Robot Operation
2.5.1 General Precautions
Before operation, become familiar with the location of all emergency stop switches.
During an emergency, always press the nearest emergency stop switch. There should
never be any emergency stop switches in the system that do not operate.
After an emergency, do not restore the emergency stop circuit until it has been determined
that the entire system is safe to restart.
If your robot is a 6-Axis type, record the pulse values of the reference points used for
calibration. For details, refer to the section Setup & Operation 3.6 Setting the Reference
Points for Calibration in the 6-Axis manipulator manual.
2.5.2 Automatic Operation
Ensure that system automatic operation is enabled only while the following requirements
are being met:
- Emergency stop switches are installed in the prescribed location and operate correctly.
- No personnel are inside the safeguarded area of the system.
- Safety procedures that are established separately for the robot system (if applicable) are
being followed.
2.5.3 Teaching Robot Points
If possible, teaching should be performed with no personnel inside the safeguarded area.
Teach mode can be used to allow the robot to be jogged or moved at slow speed when the
safeguard is open. Before going inside the safeguarded area, robot operators that need to
move the robot under servo control must switch Teach mode to ON by using the mode
selector key switch of the teach pendant. Operators then carry the teach pendant while
inside the safeguarded area. As a result, the operation mode cannot be changed from
outside the safeguarded system while somebody is inside the safeguarded area.
Auto Mode and Program Mode
With
the safeguard circuit open, the robot motors will be turned off and the robot cannot be
jogged under power. However, the robot can be moved by hand to a position with the
safeguard circuit open and the position can then be taught.
Teach Mode
The ro
bot can be jogged or moved at slow speed as long as the three position enable (dead
man) switch is engaged.
Please observe the following guidelines for teaching points:
- Robot operators must receive training that utilizes the same type of robot. Before
teaching, the operator should be thoroughly familiar with teaching procedures.
- Before teaching, remove all errors and malfunctions.
- Before the robot operator goes inside the safeguard system, confirm that the robot motors
go off when the safeguard is open and that emergency stop switches are functioning
correctly.
- The robot operator should visually check the robot system and safeguard system interior
to ensure that there are no potential hazards.
- Design the system in such a way that prevents the overall robot system from being started
up from any location while the operator is inside the safeguarded area.
