Dynamic Brake Circuit Fault (Power-up, Adv. Code 3,4,5)

What does 15 mean?

This fault indicates a general malfunction within the Dynamic Braking (DB) circuit detected immediately upon drive power-up, and it is not auto-resettable. This suggests a significant internal component failure or wiring issue within the braking chopper or its control. This fault prevents the drive from starting and operating safely.
