Overvoltage
Yaskawa · P1000
¿Qué significa ov ?
The drive's DC bus voltage has exceeded the maximum permissible limit. This typically occurs during deceleration of high inertia loads or due to a high input voltage.

- 1
Verify supply voltage at the drive's input terminals (L1, L2, L3) against the nominal input voltage rating of the Yaskawa P1000 AC Drive.
- 2
Verify drive parameters related to deceleration time (e.g., P2-01, P2-02) and ensure they are adequately set for the connected load's inertia.
- 3
Inspect the connection and integrity of the dynamic braking resistor (if installed), including its wiring to the drive's braking terminals (B1/B2).
- 4
Measure the resistance of the dynamic braking resistor (if installed) and compare it to its specified value to confirm proper functionality.
