Precharge

What does F001 mean?

For the ATV310 drive, this fault indicates an issue within the internal DC bus precharge circuit. This typically involves a fault with the charging relay control or damage to the precharge resistor, preventing the DC bus capacitors from charging correctly upon power-up.

• Charging relay control fault within the drive's precharge circuit
• Charging resistor damaged or failed in the precharge circuit
• Instability or transient issues with the main input supply voltage

Click steps to track your progress.

1. 1

   Turn the ATV310 drive off completely, wait for the display to extinguish, and then turn it back on.

2. 2

   Check the main power input connections to the drive for tightness and correct phase sequencing.

3. 3

   Verify the stability of the main input supply voltage, checking for sags or swells during power-up.
