6.1 Protective function/error description

In case of the wrong parameter setting or faulty writing, the inverter
and/or the motor may not function as commanded.

The MOSCON-E7 has many protective functions, which is displayed on
the digital operator when the fault occurs.
When the fault is detected, the fault contact output operates and the
inverter output to be shut off causing the motor to stop. The stopping
method can be selected for some faults.

• Refer to the table below for the fault display, cause and corrective

actions.

• To reset the fault, use one of the followings:

- Press the reset key on the digital operator.
- Turn the power supply off and on again.
- Turn on the fault reset terminal.

Code

Meaning

Cause

Corrective action

OC2

Short circuit

Error

The inverter

output or load

was short-circuited.

• A short-circuit or

ground fault (caused

by motor damage, worn

insulation, or a damaged

cable) at the inverter

output.

Reset the fault after

correcting.

OC1

Over current

The inverter

output current

exceeded 200%

of the rated

current instantly.

• A short-circuit or

ground fault (caused

by motor damage,

worn insulation, or a

damaged cable) at the

inverter output.

• Too large load or too

short accel/decel time.

• A magnetic switch was

switched at the inverter

output.

• A special-purpose

motor with too large

capacity for the inverter

is used.

Reset the fault after

correcting.

Code

Meaning

Cause

Corrective action

FAN

Fan stopped.

Fan at the

bottom of the

inverter is not

operating.

• Defective cooling fan

or fan cable.

Check the wiring and

replace the fan if

necessary.

• Too high ambient

temperature.

Install a cooling unit.

• Heat source nearby

the inverter.

Remove the heat

source.

OH2 Inverter

Over-Heated.

The temperature

of the inverter’s

cooling fin

exceeded

approximately95

℃

• Inverter cooling fan is

malfunctioning.

Replace the cooling

fan.(Contact Samsung)

• Too short deceleration

time.

• Too large regenerative

energy from the motor.

Increase the

deceleration time or

connect a braking

resistor (or unit).

OV Main

Over-Voltage.

The main circuit

DC voltage

exceeded the

over voltage

detection level.

200V class:410V.

400V class:820V.

• Too high power

supply voltage.

Decrease the voltage

within specification.

UV1 Main

Under-Voltage.

The main circuit

DC voltage is

below the under

voltage detection

level.

200Vclass:190V.

400Vclass:380V.

• A open-phase

occurred with the input

power supply.

• A momentary

power loss.

• Too large voltage

fluctuation in the

input power supply.

Reset the fault after

Correction.

OL3

Over-torque

Det.

There was output

of 180% of the

rated current

instantly.

• Too heavy load or too

rapid acceleration.

• Set P3.02 and

P3.03 appropriately.

• Check the

mechanical system

and correct the cause

of the over torque.
