Causes
The torque compensation gain is too large.
Electrical interference caused a problem.
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 [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.
Causes
The option card connected to connector CN5-A is not
compatible.
Causes
The option card connected to connector CN5-A is not
compatible.
Causes
The same option cards or the same type of option
cards are connected to connectors CN5-A, B, and C.
Causes
A fault occurred in the option card.
Possible Solutions
Decrease the value set in C4-01 [Torque Compensation Gain] to
make sure that the motor does not stall.
Examine the control circuit lines, main circuit lines, and ground
wiring, and decrease the effects of electrical interference.
• Find the time when the fault occurs.
• If the fault occurs at the same time as overexcitation operation,
decrease the value set in n3-13 [OverexcitationBraking (OEB)
Gain] and consider the motor flux saturation.
• Examine the sequence and input the Run command after the
motor fully stops.
• Set b3-01 = 1 [Speed Search at Start Selection = Enabled] or set
H1-xx = 61, 62 [Speed Search from Fmax or Fref] to input speed
search commands from the MFDI terminals.
• Enter the correct motor code to E5-01 [PM Motor 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 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].
Possible Solutions
Connect the option card to the correct connector.
Note:
Encoder option cards are not compatible with connector CN5-A.
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
Connect the option card to the correct connector.
Note:
Use connectors CN5-C and CN5-B to connect two encoder
option cards.
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.
