Answer:Digital Operator Display Text: OV
Discription:Overvoltage of the main circuit when running.
230V Units - trip point 400V DC or more.
460V Units - trip point 800V DC or more.
600V Units - trip point 1050V DC or more.
Possible Cause(s): High input voltage at L1, L2, and L3. The deceleration time is set too
short. Power factor correction capacitors are being used on the input to the inverter.
Corrective Action: Check the input circuit, verify the program parameters, add a braking
resistor, remove the power factor correction capacitors.
