Control Input

Illegal control input
sequence.

- 3-wire: Verify Start and Jog inputs

are not both ON.

- 2-wire: Verify that only one input

(Forward, Reverse, or Jog) is on.

FL

Function Loss

Start attempt while STOP
(Function Loss) input is off.

Verify STOP (Function Loss) input is
ON before attempting to start drive.

Under Voltage

1

1

Auto Resettable

- Low input line.
- Temporary loss of
input line.

Check input line to verify voltage is
within operating specifications.

HU

Over Voltage

1

- High input line.

- Decel time too fast.
- Overhauling load.

- Check input line to verify
voltage is within operating
specifications.
- Increase decel time.

Drive Overload

1

Excessive driven load.

Reduce the load.

OL

5

Motor Overload

1

Excessive driven load.

- Verify P-02 is set correctly.
- Reduce the load.

OH

6

Over Temperature

1

- Operating environment
is too hot.
- Fan is blocked or not
operating.

- Excessive driven load.

- Verify the ambient
temperature is < 50 °.
- Verify clearance above/ below

drive.

- Check for fan obstruction. Replace

fan if required.

- Reduce the carrier frequency (P-

64).

- Reduce the load.

OC

7

Over Current

1

(300%)

- Shaft rotation blocked.

- Excessive driven load.
- Output wiring is incorrect
or shorted.

- Check for obstructions to
shaft rotation or reduce
excessive load.
- Increase accel / decel time.
- Verify output wiring is correct.
