Questions and answers
How do I clear a fault had a short in motor wiring which threw the breaker ,fixed wiring reset breaker and nothing no power light no status light read and read so mention of reset fault but nothing tells me how
To clear a fault on a KBAC-24D after fixing motor wiring and resetting the breaker:
1. Ensure the fault (e.g., short circuit) is fully corrected.
2. If the Start/Stop Switch is present, use it to restart the drive.
3. If the Start/Stop Switch was bypassed, refer to the alternative method in Section 7.6.
4. Alternatively, disconnect AC power until all LEDs turn off, then reconnect AC power to restart the drive.
Make sure the issue (such as a short circuit) is resolved before restarting.
