Precautions for Correct Use

Precautions for Correct Use
• Robot motion is not possible until AC power is supplied High Power and has been enabled.
• Control Power must be present before High Power can be enabled.
• This equipment must be shipped and stored in a temperature-controlled environment, within the
range –25 to +55° C. The recommended humidity range must be 5 to 90%, non-condensing. It
should be shipped and stored in the supplied packaging, which is designed to prevent damage from
normal shock and vibration.
• Robot must be operated within its specific temperature ratings to ensure proper operation.
• Placing the robot on its side for extended periods of time can cause oil leaks from the harmonic
drive units. Limit the amount of time the robot is placed on its side.
• The T20 pendant can only control the robot it is directly connected to.
• Either a Front Panel or equivalent circuits are required to enable High Power to the robot.
• If the Front Panel High Power ON / OFF indicator fails, you might incorrectly assume that High Pow-
er is OFF, and the robot is safe. To prevent this, a failed indicator causes an error (-924) *Front pan-
el HIGH POWER lamp failure* and locks out the High Power enabling until you replace the indicator.
• It is recommended to use an 18 mm (minimum) thick steel plate with a maximum surface roughness
of 25 μm that is properly secured to the floor or wall as a robot mounting surface. Mounting surface
flatness must not exceed 5 mm.
• The mounting surface should be clean and prepared according to the information provided in the
manual before attempting to mount the robot.
• Do not over-tighten the tool flange setscrew. This will cause off-center alignment of the tool flange
on the quill.
• Always reduce joint motion limits with software configuration settings when hardstops are used to
restrict range of motion.
• Never release the z-axis brake while the quill clamp collar is loose or removed. This can allow the
quill to fall out of the robot.
• If Teach Pendant cabling is installed, the jumper plug or the Teach Pendant must be connected to
satisfy safety circuits and allow High Power to be enabled.
• Do not disable or bypass the High Power button. This will violate IEC 60204-1.
• Operating the robot outside of the payload and speed constraints described in this document can
damage or reduce the service life of the z-axis quill.
• If a Front Panel is not present, the High Power indicator and High Power button signals can be ac-
cessed with the XFP system cable connector.
• Attempting to release the brake while High Power is ON will automatically disable High Power. If the
robot is moving, this will cause it to stop abruptly.
• Only replace items on the robot system with the parts supplied by OMRON.
• Only use the recommended grease on the joint 3 quill. Refer to the provided Safety Data Sheet for
proper handling.
• When removing and replacing the tool flange, you must reinstall it in the same position to avoid los-
ing the calibration for the robot.
• Use surge suppression when switching inductive loads such as relays to prevent damage to the out-
put circuits.
• Any externally mounted equipment is considered robot payload. Consideration to the payload at-
tached to the Tool Flange should be made when mounting external equipment to the robot.
