What to do if my MIRKA AIROS Sander tool suddenly stops?
If your MIRKA Sander suddenly stops, you should first check the alarm status flag. Also, check both the motor drive and tool temperatures to ensure they are within acceptable limits. Finally, verify whether the tool is being overloaded, as this can cause it to stop unexpectedly.
Why my MIRKA AIROS tool does not start?
If your MIRKA Sander tool does not start, verify that the motor drive is in the ON-state by checking that D14 is not blinking. Also, confirm that the motor drive is in the RUN-state by ensuring that D4 is lit green. Lastly, inspect the cable assembly for the tool to ensure that the pins are properly connected.
How to fix Modbus RTU communication on MIRKA AIROS Sander?
If Modbus RTU communication is not working with your MIRKA Sander, verify the baud rate, parity, stop bits, and data bits settings. Check the transmit/receive indicators D29 and D30 to see if they blink, indicating activity on the bus. Ensure that the A-pin and B-pin are connected properly. Determine if adding a terminating resistor (JP2), A-pin pull-down resistor (JP3), and B-pin pull-up resistor (JP4) resolves the issue. Make sure that JP1 is not set. Finally, check the slave address by setting the JP13 jumper and using indicators D2–D3, D17–D22 to read the current address.
How to troubleshoot digital speed controller interface issues on MIRKA Sander?
If the Digital speed controller interface is not working on your MIRKA Sander, first ensure that JP1 is not set and that JP8, JP9, JP10, JP11, and JP12 are set. Then, check the voltage on a high input, which should be between 15–33 VDC. Verify the voltage on a low input, ensuring it is close to zero volts. Finally, check the GND connection to ensure it is properly connected.
What to do if Profinet I/O gateway communication is not working on MIRKA Sander?
If the Profinet I/O gateway communication is not working with your MIRKA Sander, check the gateway network configuration and the gateway Modbus RTU to Profinet I/O mapping configuration. Also, verify the 24 VDC power supply and ensure the Modbus RTU adapter cable is connected properly. Finally, confirm that JP1 is not set.
