kinetix 6500 fault codes precharge

Kinetix 6500 pre-charge faults usually relate to power supply issues (missing AC voltage, safety contactors), DC bus problems, or timing/configuration errors, often showing as general "power" or specific pre-charge state errors in RSLogix. Common fixes involve checking input AC power, verifying safety relays, ensuring proper drive enable signals, and confirming the main bus supply.

 Causes & Solutions for Pre-Charge Issues:

• Missing AC Input Power:
• Safety Circuit Issues
• Drive Enable Input
• Main Bus Enable
• Extended Power Off

Solution:

Check Power: Verify 480V (or appropriate voltage) at the drive's input terminals.

Inspect Safety: Make sure safety circuits are closed and functional.

Check Inputs: Confirm the Drive Enable hardware input is active.

Cycle Power (Carefully): Power cycle the drive, but ensure the axis is disabled first and be aware it might be a temporary fix.
