Overcurrent during

acceleration

Overcurrent flowing

in element during

acceleration

•The acceleration time CEE is

too short.

•The V/F setting is improper.

•A restart signal is input to the

rotating motor after a

momentary stop, etc.

•A special motor (e.g. motor with

a small impedance) is used.

•Increase the acceleration time

CEE.

•Check the V/F parameter.

•Use H (auto-restart) and

H (ride-through control).

•Increase or decrease the carrier

frequency H.

Overcurrent during

operation

Overcurrent flowing

in element during

acceleration

•The load fluctuates abruptly.

•The load is in an abnormal

condition.

•Reduce the load fluctuation.

•Check the load (operated

machine).

QEC 0005 Arm overcurrent at

start-up

•A main circuit element is

defective.

•Make a service call.

QEN 0004 Overcurrent (An

overcurrent on the

load side at start-up)

•The insulation of the output

main circuit or motor is

defective.

•The motor has too small

impedance.

•Check the cables and wires for

defective insulation.

QR 000A Overvoltage during

acceleration

•The input voltage fluctuates

abnormally.

①The power supply has a

capacity of 200kVA or more.

②A power factor improvement

capacitor is opened or closed.

③A system using a thyrister is

connected to the same power

distribution line.

•A restart signal is input to the

rotating motor after a

momentary stop, etc.

•Insert a suitable input reactor.

•Use H (auto-restart) and

H (ride-through control).
