Output Voltage Detection Fault

Was bedeutet voF ?

An error has occurred in the drive's internal output voltage detection circuit, leading to an inability to accurately measure output voltage. This impacts motor control and protection.

1. 1

   Cycle power to the Yaskawa P1000 AC Drive and observe if the 'voF' fault clears.

2. 2

   Inspect motor cable and all connections between the drive's output terminals (U, V, W) and the motor for physical damage, loose connections, or signs of arcing.

3. 3

   Verify all motor nameplate parameters (e.g., rated voltage, current, frequency, RPM) configured in the Yaskawa P1000 drive match the actual motor nameplate.

4. 4

   Measure motor insulation resistance (Megger test) for each motor phase to ground and between phases to check for shorts or grounds that could affect drive output.
