Causes
The current flowing in the motor is more than the
value set in L8-27 [Overcurrent Detection Gain] for
PM Control Methods.
The control method is set incorrectly for the motor.
The motor main circuit cable is too long.
Speed search does not complete at start when A1-02
= 8 [EZ Vector Control] and you use an induction
motor.
The relay or contactor on the soft-charge bypass relay
is damaged.
An overcurrent condition occurred during
overexcitation deceleration.
The output circuit between the drive and the motor is
open, and the drive output current is less than 5% of
E2-01 [Motor Rated Current (FLA)].
The option card connected to connector CN5 is not
compatible.
The option card connected to connector CN5 is not
compatible.
A fault occurred in the option card.
A fault occurred in the option card.
A fault occurred in the option card.
A fault occurred in the option card.
The ambient temperature is high and the heatsink
temperature of the drive is more than the value set in
L8-02 [Overheat Alarm Level].
The ambient temperature is high and the heatsink
temperature of the drive is more than the oH1
detection level.
The thermistor wiring that detects motor temperature
is defective.
The motor has overheated.

Possible Solutions
Correct the value set in L8-27.
Set A1-02 [Control Method Selection] correctly.
Replace the drive with a larger capacity model.
When E9-01 = 0 [Motor Type Selection = Induction (IM)], set b3-
24 = 2 [Speed Search Method Selection = Current Detection Speed
Search].
• Re-energize the drive.
• If the fault stays, replace the control board or the drive.
• Decrease the value set in n3-13 [OverexcitationBraking (OEB)
Gain].
• Decrease the value set in n3-21 [HSB Current Suppression
Level].
Close the disconnected output circuit between the drive and the
motor.
Connect the option card to the correct connector.
Note:
Encoder option cards are not compatible with connector CN5.
1. De-energize the drive.
2. Refer to the option card manual and correctly connect the
option card to the connector on the drive.
1. De-energize the drive.
2. Make sure that the option card is correctly connected to the
connector.
3. If the problem continues, replace the option card.

• Measure the ambient temperature.
• Increase the airflow in the control panel.
• Install a cooling device (cooling fan or air conditioner) to lower
the ambient temperature.
• Remove objects near the drive that are producing too much heat.
• Measure the ambient temperature.
• Increase the airflow in the control panel.
• Install a cooling device (cooling fan or air conditioner) to lower
the ambient temperature.
• Remove objects near the drive that are producing too much heat.
Correct wiring errors.
• Check the load level, acceleration/deceleration time, and motor
start/stop frequency (cycle time).
• Decrease the load.
• Increase the values set in C1-01 to C1-04 [Acceleration/
Deceleration Times].
• Set E2-01 [Motor Rated Current (FLA)] correctly to the value
specified by the motor nameplate.
• Make sure that the motor cooling system is operating correctly,
and repair or replace it if it is damaged.
• Adjust E1-04 to E1-10 [V/f Pattern Parameters]. For motor 2,
adjust E3-04 to E3-10. Decrease the values set in E1-08 [Mid
Point A Voltage] and E1-10 [Minimum Output Voltage].
Note:
If E1-08 and E1-10 are set too low, the overload tolerance will
decrease at low speeds.
