Cause: Control power supply fault comes when the input voltage is not within the allowable range. This can prevent the drive from operating correctly or cause erratic behavior.
"Err08" fault in inovance MD290 drive indicate "Control power supply fault". This means a problem with the power supply that provides voltage to the drive's internal circuitry.
Troubleshooting Steps
-
Check the Control Power Supply:
- Visually inspect the power supply: Look for signs of physical damage, such as burns or discoloration.
- Measure the output voltage: Use a multimeter to measure the output voltage of the control power supply. Compare it to the specified value in the drive's manual.
- Replace the power supply if necessary: If the power supply is damaged or has the wrong output voltage, replace it with a new one of the correct specifications.
-
Inspect Connections:
- Check the connections: Ensure that the connections between the control power supply and the drive are tight and free of corrosion.
- Clean the connections if necessary: If the connections are dirty or corroded, clean them with a contact cleaner.
-
Verify Drive Internal Components:
- Check for internal faults: If the control power supply appears to be functioning correctly, there might be a fault within the drive's internal circuitry.
