ovd on DELTA inverters: Over-voltage during deceleration

DELTA inverters: MS300

Disconnect the supply and wait for the capacitors to discharge before opening the inverter or touching its terminals.

Common causes

1. 1Deceleration too fast, the motor regenerates
2. 2High-inertia load

Try first

1. 1Increase the deceleration time (Pr.01-13)
2. 2Enable over-voltage stall prevention (Pr.06-01)
3. 3Add a suitable braking resistor if a fast stop is needed
