Data from a servo amplifier is not received
Check the communication cable connection and conductivity
A communication error was detected between the servo amplifier and PC.
Check the communication cable connection and conductivity. If it comes back, contact your service
provider.
The absolute position data in the position detector was lost. The voltage of the robot-arm or additional
axis's backup battery may be dropping.
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 the error occurs while using the controller with any other robot, replace the controller battery, then set
the origin using the ABS method. Re-teaching is unnecessary since position data can be fully restored if
the origin is set using the ABS method. Refer to separate "Instruction Manual/Robot Arm Setup and Main -
tenance" for ABS method.
If the voltage of robot battery is low, reset the error, and set up the origin by ABS method. Then, the robot
can be operated without replacing the battery. However, this error occurs again when the controller is re-
turned on. It is recommended to replace the battery at the earliest opportunity.
An error was detected in the position detector's one rotation data.
Turns off the power supply once and turns on again. If it comes back, contact your service provider.
Position deviation by scattered encoder data occurred
Turns off the power supply once and turns on again. Check that there is not a source of excessive
vibration. If it comes back, contact your service provider.
A CRC error was detected in the data from servo amplifier.
Turns off the power supply once and turns on again. If it comes back, contact your service provider.
The command position from the RC is abnormally large.
Turns off the power supply once and turns on again. If it comes back, contact your service provider.
An error was detected in the communication frame from 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 communication information from the RC.
Check the communication cable connection and conductivity. If it comes back, contact your service
provider.
Pulses skipped in the position detector's feedback signal.
Check the detector cable connection and conductivity. If it comes back, contact your service provider.
Displacement occurred in the feedback amounts between the detectors on the motor edge and on the
machine edge.
Check the detector cable connection and conductivity. If it comes back, contact your service provider.
A CRC 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.
