YASKAWA TOEPC71061782C GA800 Drive Installation & Primary Operation
Causes
If the drive detects the fault at start or in the low
speed range (10% or less) and n8-57 = 1 [HFI
Overlap Selection = Enabled] for PM Control
methods, the high frequency injection gain is too
high.
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 you set
A1-02 = 8 [EZ Vector Control] and use an induction
motor.
An overcurrent occurred during overexcitation
deceleration.
The option connected to connector CN5-A is not
compatible.
The option card connected to connector CN5-A is not
compatible.
The same option cards or the same type of option
cards are connected to connectors CN5-A, B, and C.
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 option connected to connector CN5-B is not
compatible.
The option card connected to connector CN5-B was
changed during operation.
The same option cards or the same type of option
cards are connected to connectors CN5-A, B, and C.
A fault occurred in the option card.
A fault occurred in the option card.
20 Troubleshooting
Possible Solutions
• Set E5-xx [PM Motor Parameters] correctly or do Rotational
Auto-Tuning.
• Decrease the value of n8-41 [HFI P Gain] in 0.5 unit increments.
Note:
Set n8-41 > 0.0 for an ordinary IPM motor.
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].
• Decrease the value set in n3-13 [OverexcitationBraking (OEB)
Gain].
• Decrease the value set in n3-21 [HSB Current Suppression
Level].
Connect the option to the correct connector.
Note:
Encoder options are not compatible with connector CN5-A.
1.
De-energize the drive.
2.
Refer to the option card manual and correctly connect the
option card to the connector on the drive.

Note:
Use connectors CN5-C and CN5-B to connect two encoder
option cards.
1.
De-energize the drive.
2.
Make sure that the option card is correctly connected to the
connector.
3.
