A collision was detected.
1) If the robot has stopped by interference with peripheral equipment, move the arm to part from peripheral
equipment using jog operation. Depending on the level of collision, the collision detection error may occur
again. In that case, turn on the servo power again and do jog operation. If it still recurs, release the brake
and move the arm by hand.
2) If this error occurs without having collided, please adjust the collision detection level. If collision is
detected incorrectly during automatic operation, enlarge the setting value of the parameter (COLLVL)
corresponding to axis. If collision is detected incorrectly during jog operation, enlarge the setting value of
the parameter (COLLVLJG) corresponding to axis. However, since the detection level drops by enlarging
the set value, don't enlarge too much. And, the incorrect detection can be reduced when setup value of
parameter (HNDDATn、 WRKDATn) is correct.
3) If the speed excessive error has occurred at the same time, the torque alteration by rapid speed change
may be detected as a collision state. Remove other causes of the error and confirm movement again.
4) In case of operation under the environment of low temperature or after the long term stoppage, the col -
lision detection error may occur by viscous transmutation of the grease used. In such a case, operate by
accustoming at low speed (warm-up), or use the warm-up operation mode.
The additional axis exceeded the regenerative performance limit.
Check the regenerative capacity and parameters for the additional axis.
If it comes back, contact your service provider. Regeneration resistance may be disconnected.
The converter's regenerative performance limit was exceeded.
Wait at least 15 minutes in the power ON state, and then turn the power OFF and ON.
If it comes back, contact your service provider. Regeneration resistance may be disconnected.
An abnormality may have occurred in the position detector cable connection.
1) Turn the power OFF and ON once. If it comes back, contact your service provider.
2) When instantaneous power failure errors occur simultaneously, turn on the power supply again.
Initial communication with the encoder was not possible
Check the encoder cable connection
Communication between the encoder and detector was cut off
Check the encoder cable connection
Communication with the position detector was cut off.
Confirms the signal cable of the machine cable and the locomotion-axis cable etc. If it comes back, contact
your service provider.
An abnormality may have occurred in the communication cable connection.
Turn the power OFF and ON once. If it comes back, contact your service provider.
CR800-R/CR800-Q: Check the connection between the robot CPU system and the controller.
An abnormality may have occurred in the servo axis settings (parameters, rotary switches).
Turn the power OFF and ON once. If it comes back, contact your service provider.
CR800-R/CR800-Q: Check the connection between the robot CPU system and the robot controller. And
when turning the power ON, turn on the switch of the robot controller, then of the
robot CPU.
Using the additional axis: Confirms the axis setting switch, cable connection with robot controller, setting
parameter, condition of power supply of additional axis amplifier, type of additional
axis amplifier etc. When applying a power supply, turn on the additional axis
amplifier first, then turn on the controller. And when turning the power ON, turn
on the switch of the drive unit, then of the robot CPU.
Abnormality occurred in data reception from a servo amplifier
Check the communication cable connection and conductivity
