Troubleshooting: Mitsubishi Robot Alarm Codes
Identify system faults quickly to minimize production stoppages:
- Error C0010 (Servo Error): Often indicates an issue with the Servo Amplifier or Motor feedback.
- Error L3900 (Communication Error): Check internal bus cables or CC-Link interface boards.
- Error H0010 (Battery Alarm): Time to replace the Encoder Batteries to avoid losing robot origin data.
- Error M0100 (Position Error): Triggered by axis deviations; may require drive recalibration.
Mitsubishi Robot Controller Architecture
Mitsubishi robot controllers contain several important modules working together.
Typical controller architecture includes:
Executes robot programs and manages system operations.
Control motor movements and robot axes.
Provide stable electrical power to controller components.
Allow communication with PLC systems and external automation equipment.
Together these modules ensure precise robot control and reliable automation performance.
MELFA Robot Programming
Mitsubishi robots use the MELFA-Basic programming language.
This programming environment allows engineers to:
- create robot motion programs
- integrate robots with PLC systems
- implement automation logic
Programs can be developed using teach pendants or offline programming tools.

FAQ C Mitsubishi Robot Spare Parts
Q: How do I find the correct part number for my Mitsubishi robot?
A: Refer to the label on the component or the Maintenance Manual specific to your CR controller. Most Mitsubishi parts start with an alpha-numeric code (e.g., MDS- or JZRCR-).
Q: Does Mitsubishi use a specific programming language?
A: Yes, Mitsubishi robots use MELFA-BASIC(currently version VI), which is highly optimized for complex motion and PLC communication.
Q: Are SCARA robot cables different from 6-axis cables?
A: Yes. SCARA robots (RH series) have specific internal wiring layouts due to their high-speed rotational Z-axis. Always verify the robot model before ordering.
