BR WIRING

Hva betyr 7111 ?

The brake resistor connected to the ABB ACS800 drive has been incorrectly wired, or there is a fault in the resistor's internal wiring or connections. Incorrect wiring (3.17 FW 5 bit 1) can prevent proper braking operation, lead to unexpected drive behavior, and potentially cause damage to the drive or resistor.

• Wrong physical connection of the brake resistor to the drive's brake chopper terminals (e.g., incorrect polarity, wrong terminals).
• Damage to the brake resistor's terminals, internal wiring, or the resistor element itself.
• Loose or corroded connections in the wiring between the drive and the brake resistor.

1. 1

   Carefully check the brake resistor connection against the ABB ACS800 drive's wiring diagram in the manual, ensuring correct polarity and terminal usage.

2. 2

   Inspect the brake resistor for any visible damage, such as burnt areas, cracks, loose terminals, or broken wires.

3. 3

   Measure the resistance of the brake resistor using a multimeter and compare it to its specified value to confirm resistor integrity.

4. 4

   Verify the continuity and proper insulation of the wiring between the drive's brake chopper terminals and the brake resistor itself.
