SIEPCYEUOQ2V01A Q2V Technical Manual
Causes
The gain during overexcitation operation is too
large.
The drive received a Run command while the motor
was coasting.
In PM Control Methods, the setting of the motor
code is incorrect.
If the drive detects the fault at start or in the low
speed range (10% or less) and n8-57 = 1 [High-
Freq Injection = Enabled] for PM Control methods,
the high frequency injection gain is too high.
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] and use an induction
motor.
An overcurrent occurred during overexcitation
deceleration.
Causes
When A1-02 = 5, 6, 8 [Control Method = PM
OLVector, PM AOLVector, or EZ Vector], the output
current is more than the value set in L8-27
[OverCurr Det Gain].
Causes
The option connected to connector CN5 is not
compatible.
Causes
You changed the option card connected to
connector CN5 during operation.
Causes
A fault occurred in the option card.
Causes
A fault occurred in the option card.
Possible Solutions
• Find the time when the fault occurs.
• If the fault occurs at the same time as an overexcitation
operation, decrease n3-13 [OverExcBr Gain] and consider the
motor flux saturation.
• Examine the sequence and input the Run command after the
motor fully stops.
• Set b3-01 = 1 [SpSrch@Start Selection = Enabled] or set H1-
xx = 67, 68 [SpdSrch Fmax, SpdSrch Fref] to input speed
search commands from the MFDI terminals.
• Enter the correct motor code to E5-01 [PM Mot Code
Selection] as specified by the PM motor.
• For specialized motors, refer to the motor test report and set
E5-xx [PM Motor Settings] correctly.
• Set E5-xx [PM Motor Parameters] correctly or do Rotational
Auto-Tuning.
• Decrease the value of n8-41 [HFI PoleDet Pgain] in 0.5-unit
increments.
Note:
Set n8-41 > 0.0 for an ordinary IPM motor.
Set A1-02 [Control Method] correctly.
• Replace the drive with a larger capacity model.
• Decrease C6-02 [Carrier Frequency Selection]. Or set C6-02
= B.
When E9-01 = 0 [Motor Type Selection = IM], set b3-24 = 2
[SpSrch Method Selection = Current Det2].
• Decrease n3-13 [OverExcBr Gain].
• Decrease n3-21 [OverExcBr Current Level].
Possible Solutions
Correct the value set in L8-27.
Possible Solutions
Connect a correct option.
Possible Solutions
1. De-energize the drive.
2. Refer to the option card manual and correctly connect the
option card to the connector on the drive.
Possible Solutions
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.
Possible Solutions
1. De-energize the drive.
