102 YASKAWA TOEPC71061732E HV600 Drive Installation & Primary Operation
Code Name Causes Possible Solutions
The current flowing in the motor is more than the
value set in L8-27 [Overcurrent Detection Gain] for
PM Control Methods.
Correct the value set in L8-27.
The control method is set incorrectly for the motor. Set A1-02 [Control Method Selection] correctly.
The motor main circuit cable is too long. Replace the drive with a larger capacity model.
Speed search does not complete at start when A1-02
= 8 [EZ Vector Control] and you use an induction
motor.
When E9-01 = 0 [Motor Type Selection = Induction (IM)], set b3-
24 = 2 [Speed Search Method Selection = Current Detection Speed
Search].
The relay or contactor on the soft-charge bypass relay
is damaged.
• Re-energize the drive.
• If the fault stays, replace the control board or the drive.
An overcurrent condition occurred during
overexcitation deceleration.
• Decrease the value set in n3-13 [OverexcitationBraking (OEB)
Gain].
• Decrease the value set in n3-21 [HSB Current Suppression
Level].
OD Output Disconnect
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)].
Close the disconnected output circuit between the drive and the
motor.
oFA00 Option Not Compatible with Port
The option card connected to connector CN5 is not
compatible.
Connect the option card to the correct connector.
Note:
Encoder option cards are not compatible with connector CN5.
oFA01 Option Fault/Connection Error
The option card connected to connector CN5 is not
compatible.
1. De-energize the drive.
2. Refer to the option card manual and correctly connect the
option card to the connector on the drive.
oFA05 and
oFA06
Option Card Error Occurred at
Option Port CN5
A fault occurred in the option card. 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.
oFA10, oFA11
Option Card Error Occurred at
Option Port CN5
A fault occurred in the option card. 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.
oFA12 to
oFA17
Option Card Connection Error (CN5)
A fault occurred in the option card. 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.
oFA30 to
oFA43
Communication Option Card
Connection Error (CN5)
A fault occurred in the option card. 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.
oH Heatsink Overheat
The ambient temperature is high and the heatsink
temperature of the drive is more than the value set in
L8-02 [Overheat Alarm Level].
• 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.
oH1 Heatsink Overheat
The ambient temperature is high and the heatsink
temperature of the drive is more than the oH1
detection level.
• 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.
oH3 Motor Overheat (PTC Input)
The thermistor wiring that detects motor temperature
is defective.
Correct wiring errors.
oH4 Motor Overheat Fault (PTC Input)
The motor has overheated. • 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.
