2.4 Driver Unit/Simple Absolute Unit Alarm Causes and Countermeasures
C2-23
ME0384-4A
Chapter 2 Troubleshooting
Alarm name Causes/countermeasures
Cause: The temperature of the controller internal parts has exceeded
the temperature defined for each actuator.
1) Operating with load
conditions exceeding
the specified range.
2) The ambient
temperature is high.
3) The load on the
motor is large due to
external force.
4) Defective parts inside
the RCON system.
(When detail code is 0008H or 0009H in the alarm list in the
teaching tool, it is an error of the 200V power supply unit)
Countermeasure: 1) Revise the operation conditions, such as
decreasing the acceleration/deceleration speed.
2)
Lower the ambient temperature of the RCON system.
3) Confirm that there are no assembly errors in
machine components.
Note: This error does not normally occur. If it occurs,
confirm that it is not (1) to (3) above. If the
same problem reoccurs, there may be an
RCON system failure. Contact IAI.
adjustment error
Cause: During the current detection sensor status check conducted in
the startup initialization process, a sensor error was found.
1)
Failure of the current detection sensor and peripheral components.
2) Offset adjustment failure.
3) An external force was applied to the actuator at power ON.
Countermeasure: If the same error occurs even after rebooting the
power with the actuator stationary, replace the circuit
board or adjust the offset. Contact IAI.
0CC Control power supply
voltage error
Cause: Driver unit control power supply voltage has increased to or
above 28.8 V (120% of 24 VDC).
1) Control power supply voltage rise
2) Malfunction of parts inside the RCON system
Countermeasure: 1)
Confirm that voltage of 24 VDC
±
10% is being applied to
the gateway unit control power connector. If the voltage
is low, the 24 VDC power supply may have failed.
S
Driver
Welded Detection Error
Cause: Welding on drive cutoff relay inside controller.
Countermeasure: The relay or controller must be replaced.
Please contact IAI.
