A blog we posted earlier this week about the Micromaster 420 troubleshooting referenced the Faults and Alarms list for the Micromaster series, so we decided that it would make sense to make the list of Micromaster 420 Faults and Alarms directly available. This is from the corresponding manual for the Micromaster 420 series, but it is buried within the manual which most people most likely don’t even have. Hopefully, this helps with your troubleshooting.
The Siemens 6AV2124-0GC01-0AX0 is a TP700 Comfort Panel with a 7 inch widescreen TFT display. It has 12MB of user memory, Windows CE 6.0, as well as Profinet and MPI/Profibus DP interfaces. The panel uses a 24V DC supply input, with a permissible range from 19.2 V to 28.8 V. It’s input current has a consumption of 0.5 A.
When connecting the power supply, be sure to switch it off before connecting to the HMI. Check the correct polarity of the cables using the interface marking on the back of the panel. Once the power supply connector is in the corresponding socket of the HMI, switch on the power. The HMI is equipped with a reverse polarity protection circuit. Once the power is turned on, the 6AV2124-0GC01-0AX0 display will light up. If the panel fails to start, you may have crossed the cables at the power supply connector. Once the operating system starts, the desktop with the Start Center is displayed. The panel will automatically switch to “Transfer” mode during the initial startup if either no project is loaded on the HMI device, or if at least one data channel has been configured.
The backlight on the 6AV2124-0GC01-0AX0 is good for roughly 80,000 hours. If your panel has been in use for longer and you are experiencing issues, you may want to consider contacting MRO Electric to order a replacement.
The 6AV2124-0GC01-0AX0 offers excellent functionality and is configured exclusively with the outstanding HMI software, WinCC. The software is integrated into the engineering framework Totally Integrated Automation Portal (TIA Portal). Additionally, there a number of software add-ons available. These include WinCC/Sm@rtServer, WinCC/Audit, UPS, Microsoft Excel Viewer, Microsoft PDF Viewer, Microsoft Word Viewer, and printer driver. This panel is certified by a number of organizations to be used on marine vessels and certain hazardous areas.
The FANUC A06B-6105-H002 is a servo amplifier used with the FANUC Robot Module R-2000iA. Usually, these amplifiers are factory set for operation, so you do not need to set or adjust them. However, if you need to configure or troubleshoot your A06B-6105-H002, please follow the instructions below. Take note that before touching your FANUC Robotic drives, you should always check the voltage at the screw above LED “D7” to ensure that the remaining voltage is not higher than 50V.
The following table highlights the various LEDs on the A06B-6105-H002 and their meanings.
Lights when the power supply circuit inside of the servo amplifier outputs a voltage of +5V normally.
Lights when the power supply circuit inside of the servo amplifier outputs a voltage of +3.3V normally.
Lights when an emergency stop signal is input to the servo amplifier.
Lights when the servo amplifier detects an alarm.
Lights when the servo amplifier is ready to drive the servo motor.
Lights when the communication between the servo amplifier and the main board is normal.
Lights when the watchdog alarm is detected in the servo amplifier.
Lights when the DC LINK circuit inside the servo amplifier is charged to reach a specific voltage.
If you need to replace the A06B-6105-H002 amplifier on your R-2000iA, ensure that you begin by first turning off the control unit main power. Next, detach the amplifier cover and pull out the cable. Check the screw above LED D7 with a DC voltage tester to make sure the remaining voltage is not above 50V. Remove the two screws located on the top of the amplifier. At the middle top of the drive, there is an M5 screw that fastens the amplifier during the transport of the cabinet. After installation of the cabinet, remove the screw as this will help improve maintainability.
After these steps are complete, you can pull the amplifier toward you using the handles located at the top and bottom. Be careful not to touch any components on the lower part of the drive’s PCB, and try not to damage any cables routed under the amp when pulling it out. Use a slanted angle when pulling it out. MRO Electric and Supply has spare FANUC Robotics AC and DC Drives available. For more information or to request a quote, please email firstname.lastname@example.org or call 800-691-8511.
You can easily install a replacement by reversing the steps above. Lastly, be sure to check out our other robotics articles
