Connection error mains choke

What does F8813 mean?

This fatal error indicates a connection problem or an incorrect mains choke detected by the IndraDrive MPx02. The mains choke is essential for input current smoothing and harmonic suppression, and an issue with it compromises the drive's input power quality and reliability.

• Mains choke not connected or incorrectly wired to the IndraDrive MPx02.
• Resistance of the mains choke outside the permissible range, indicating a fault within the choke itself (e.g., open circuit, shorted winding).
• Incorrect mains choke type or impedance for the IndraDrive MPx02 and supply voltage.
• Loose connections or damaged terminals at the choke or drive input.
• Internal measurement circuit fault in the IndraDrive MPx02 that monitors the choke.

Click steps to track your progress.

1. 1

   Power off the IndraDrive MPx02 and verify that the mains choke is correctly wired to the drive's input terminals, checking phase rotation if applicable.

2. 2

   Measure the resistance of each winding of the mains choke to ensure continuity and correct values (refer to choke specifications).

3. 3

   Confirm that the installed mains choke is the correct type and impedance recommended for the specific IndraDrive MPx02 model and input voltage.

4. 4

   Inspect all power connections to and from the mains choke for tightness, corrosion, or damage.

5. 5

   If the choke and wiring are verified as correct, an internal issue within the IndraDrive MPx02's input stage may be present, requiring service.
