Error no. H1110 *
1Error list
H1110 * Error message Servo communication timeout
Cause Data from a servo amplifier is not received
Measures Check the communication cable connection and conductivity
H111n
(n indicates the
axis number (1
to 8).)
Error message SRV-AMP comm. error
Cause A communication error was detected between the servo amplifier and PC.
Measures Check the communication cable connection and conductivity. If it comes back, contact your service
provider.
H112n *
(n indicates the
axis number (1
to 8).)
Error message Encoder ABS position data lost
Cause 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.
Measures 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.
H113n *
(n indicates the
axis number (1
to 8).)
One of the errors below is detected.
Please take measures corresponding to an error message.
Error message Encoder per rotation data error
Cause An error was detected in the position detector's one rotation data.
Measures Turns off the power supply once and turns on again. If it comes back, contact your service provider.
Error message Encoder data scattered
Cause Position deviation by scattered encoder data occurred
Measures 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.
H114n *
(n indicates the
axis number (1
to 8).)
Error message SRV-AMP Comm. data error (CRC)
Cause A CRC error was detected in the data from servo amplifier.
Measures Turns off the power supply once and turns on again. If it comes back, contact your service provider.
H115n *
(n indicates the
axis number (1
to 8).)
Error message Large command position
Cause The command position from the RC is abnormally large.
Measures Turns off the power supply once and turns on again. If it comes back, contact your service provider.
H116n *
(n indicates the
axis number (1
to 8).)
Error message SRV-AMP Comm. error (frame)
Cause An error was detected in the communication frame from servo amplifier.
Measures Turns off the power supply once and turns on again. If it comes back, contact your service provider.
H117n *
(n indicates the
axis number (1
to 8).)
Error message SRV-AMP Comm. error (info)
Cause An error was detected in the communication information from the RC.
Measures Check the communication cable connection and conductivity. If it comes back, contact your service
provider.
H118n *
(n indicates the
axis number (1
to 8).)
Error message Servo amplifier feedback error 1
Cause Pulses skipped in the position detector's feedback signal.
Measures Check the detector cable connection and conductivity. If it comes back, contact your service provider.
H119n *
(n indicates the
axis number (1
to 8).)
Error message Servo amplifier feedback error 2
Cause Displacement occurred in the feedback amounts between the detectors on the motor edge and on the
machine edge.
Measures Check the detector cable connection and conductivity. If it comes back, contact your service provider.
H1200 * Error message SRV-AMP Comm. data error (CRC)
Cause A CRC error was detected in the communication data from the servo amplifier.
Measures Turns off the power supply once and turns on again. If it comes back, contact your service provider.
