A data ID error was detected in the communication data from the servo amplifier.
Turns off the power supply once and turns on again. If it comes back, contact your service provider.
An axis No. error was detected in the communication data from the servo amplifier.
Turns off the power supply once and turns on again. If it comes back, contact your service provider.
A Sub ID error was detected in the communication data from the servo amplifier.
Turns off the power supply once and turns on again. If it comes back, contact your service provider.
An No. of received frames error was detected in the communication data from the servo amplifier.
Turns off the power supply once and turns on again. If it comes back, contact your service provider.
An error was detected in the servo parameter.
Confirms whether the type displayed on the rated name plate of controller and T/B is the same.
If different, restores the type data (backup data).
If it comes back, contact your service provider.
Initial communication could not be established with the low-speed serial type absolute position linear scale.
Check the detector cable connection and conductivity. If it comes back, contact your service provider.
The serial data of absolute position was abnormally transmitted.
Check the detector cable connection and conductivity. Moreover, confirms carefully that the moving posi -
tion of the robot has not deviated, and if it has deviated, sets up the origin again. Refer to separate
"Instruction Manual/Robot Arm Setup and Maintenance" for operation method.
If it comes back, contact your service provider.
Absolute position serial data format was incorrect.
Check the detector cable connection and conductivity. Moreover, confirms carefully that the moving posi -
tion of the robot has not deviated, and if it has deviated, sets up the origin again. Refer to separate
"Instruction Manual/Robot Arm Setup and Maintenance" for operation method.
If it comes back, contact your service provider.
The absolute position data fluctuated when the power was turned ON.
Check whether the axis moved due to arm dropping or external force when the power was turned ON.
Excessive displacement was detected in the feedback amounts between the detector and the MP scale.
Turn the power OFF and ON once. If it comes back, contact your service provider.
Excessive displacement was detected in the feedback amounts between the detector and the MP scale.
Turn the power OFF and ON once. If it comes back, contact your service provider.
An error was detected in the position detector's multi-rotation data.
If this error occurs while using the robot controller with the RV-8CRL or RV-5AS, there may be a problem
with the encoder. Please contact the manufacturer.
If this error occurs while using the controller with any other robot, the origin position may be misaligned.
Cycle the power of the controller, then set the origin using the ABS method. Refer to separate "Instruction
Manual/Robot Arm Setup and Maintenance" for ABS method.
(Even if this warning occurs, unless the controller is re-turned on, it can operate perfectly. However, when
re-turning on the controller, the position gap may occur. Please be sure to set up the origin by ABS
method after re-turning on the controller power supply. Current position data returns to the normal posi -
tion before error occurrence.)
When it comes back, contact to the dealer.
