16.1. Error number list
This section describes the cause and countermeasure to take for the error numbers when errors related to
the predictive maintenance function occurs. In event of an error, refer to this chapter and take appropriate
action.
For other error numbers described in this chapter, refer to the separate volume, "Troubleshooting in
CR800 Series Controller Instruction Manual".
When an error occurs, the ERROR LED in front of the robot controller lights up or flashes.
ERROR LED status Description
On Low-level error, or warning occurred.
Flashing High-level error occurred.
Off Normal operation.
The meaning of the error numbers is explained below.
16.1.1. Common to predictive maintenance functions
Functions such as consumption degree calculation of the predictive maintenance function assume that the
same controller and the same mechanism are used.
When the serial number of the connected robot was changed, the error (H.7100) is output to notify that
effect upon power ON in order to prevent reliability of the predictive maintenance function from decreasing
after exchanging the robot or robot controller.
Also, in order to prevent writing backup data to a different robot, the error (H.7101) occurs when attempting
restoration if the serial number of the robot body is different from the backup data value, and restoration
cannot be performed.
Also, in case the backed up data format has been changed as a result of version upgrade of the robot
controller and it is attempted to write the old format data, error H.7102 is output to notify that effect.

• Errors marked with an * are those required for power reset.
Take action according to the countermeasures given.
• The error type is indicated by a four-digit number.
• There are 3 types of errors.
H:High-level error...............Servo turns off.
L:Low-level error...............Operation stops.
C:Warning...............Operation continues.
• "n" indicated in the last one digit of the error number is the robot axis number.
Example) Motor overcurrent error of H0931J1 axis.
