Hva betyr 64 ?

This fault indicates issues with the drive's main input supply. It can be triggered if the main input switch is open, or if the Main Circuit Breaker (MCB) feedback signal is missing after the settled time defined by parameter P2.4.6 (Breaker Ack Time) has elapsed.

• Input power supply voltage outside normal operating range.
• Loss of one or more phases of the AC input supply.
• Input voltage stability issues.
• Supply fuse blown or circuit breaker tripped.

1. 1

   Check the main power switch supplying the drive and ensure it is in the closed (ON) position.

2. 2

   Check the functionality of the Main Circuit Breaker (MCB) and verify its trip status.

3. 3

   Verify the signal wiring for the MCB feedback input, ensuring proper connection and signal integrity.

4. 4

   Review parameter P2.4.6 (Breaker Ack Time) to ensure it is set appropriately for the MCB's feedback delay.
