XC Series

Before using the robot
(Be sure to read the following notes.)
At this time, our thanks for your purchase of this OMRON XC series SCARA
robot.
1.
Please be sure to perform the following tasks before using the robot.
Failing to perform the tasks below will require re-teaching of the robot since
the origin position cannot be set to the same previous position. Robot malfunc-
tions (vibration, noise) may also occur.
The origin position of the XC series robots is adjusted to the robot arm exten-
ded position at the factory prior to shipment, so the reference or standard coor-
dinates are temporarily set.
The customer should set the origin position before any other job. There are 2
types of origin position settings as shown below.
[1] Setting the robot arm extended position (the origin position adjusted at the
factory prior to shipment) as the origin position
(When setting the origin position with the robot arm extended, you must
check that there will not be any interference from any peripheral equip-
ment during the next absolute reset.)
[2] Setting a position OTHER than the robot arm extended position (the ori-
gin position adjusted at the factory prior to shipment) as the origin position
[1] To set the robot arm extended position (the origin position adjusted at the
factory prior to shipment) as the origin position.
Absolute Reset
The XC series robots only require the absolute reset to be performed once
when the robot is introduced.
Once the absolute reset is performed, you do not need to reperform it when
the power is turned on next time.
Set the origin position while referring to absolute reset methods in "3. Ad-
justing the origin" in Chapter 4 of this manual and in "Absolute Reset" of
the "OMRON Robot Controller User's Manual". Setting of reference coordi-
nates is not required in the above case.
CAUTION
NEVER ENTER THE ROBOT MOVEMENT RANGE ONCE THE ROBOT
SERVO IS TURNED ON AS THIS IS EXTREMELY HAZARDOUS.

[2] To set a position OTHER than the robot arm extended position (the origin
position adjusted at the factory prior to shipment) as the origin position.
1. Absolute reset
The XC series robots only require the absolute reset to be performed once
when the robot is introduced.
Once the absolute reset is performed, you do not need to reperform it when
the power is turned on next time.
Set the origin position while referring to absolute reset methods in "3. Ad-
justing the origin" in Chapter 4 of this manual and in "Absolute Reset" of
the "OMRON Robot Controller User's Manual".
Set the origin position with the absolute reset.
2. Afxing the origin position sticker
Set in emergency stop when absolute reset is complete, and immediately
afx the origin point sticker according to instructions in "6. Afxing Stick-
ers for Origin Positions, Movement Directions and Axis Names" in Chapter
4 of this manual.
3. Setting the reference coordinates
Set the reference coordinates while referring to instructions in "5. Setting the
Reference Coordinates" in Chapter 4 of this manual and also to "Setting the
Reference Coordinates" in the "OMRON Robot Controller User's Manual".
Robot malfunctions (vibration, noise) may occur if the reference coordinates
are not set correctly.
Even though there is no problem with the robot, the following error messages
are issued when the robot and controller are connected and power rst turned
on.
(Actual error messages may differ according to how the robot and controller
are connected.)
Error messages issued when robot & controller are connected (YRC)
17.81 : D?.ABS.battery wire breakage
17.83 : D?.Backup position data error 1
17.85 : D?.Backup position data error 2
17.92 : D?.Resolver disconnected during power off
17.93 : D?.Position backup counter overow
etc.
2. If the X, Y or R axis rotation angle is small.
If the X, Y or R axis rotation angle is smaller than 5° so that it always moves in
the same position, an oil lm is difcult to be formed on the joint support bear-
ing, possibly leading to damage to the bearing. In this type of operation, add a
movement so that the joint moves through 90° or more, about 5 times a day.
CAUTION
NEVER ENTER THE ROBOT MOVEMENT RANGE ONCE THE ROBOT
SERVO IS TURNED ON AS THIS IS EXTREMELY HAZARDOUS.

CHAPTER 1 Using the Robot Safely
3 Special Training for Industrial Robot Operation
Companies or factories using industrial robots must make sure that every
person, who handles the robot such as for teaching, programming, movement
check, inspection, adjustment and repair, has received appropriate training and
also has the skills needed to perform the job correctly and safely.
Since the XC series robots fall under the industrial robot category, the user
must observe local regulations and safety standards for industrial robots, and
provide special training for every person involved in robot-related tasks (teach-
ing, programming, movement check, inspection, adjustment, repair, etc.).
