YASKAWA TOEPC7106171GA FP605 Drive Installation & Primary Operation
Causes
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 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 and B.
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 and B.
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.
20 Troubleshooting
Possible Solutions
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].
