SIEPYEUOQ2A01G AC Drive Q2A Technical Manual 293
Code Name Causes Possible Solutions
The main circuit capacitors have become
unserviceable.
• Examine the capacitor maintenance time in monitor U4-05
[Capacitor Maintenance].
• If U4-05 is more than 90%, replace the capacitor. Contact the
manufacturer or your nearest sales representative for more
information.
• Examine the input power for problems.
• Re-energize the drive.
• If the alarm stays, replace the circuit board or the drive.
Contact the manufacturer or your nearest sales representative
for more information.
Note:
• The drive detects this error if the DC bus voltage changes irregularly without regeneration.
• If the drive detects this error, the terminal assigned to H2-01, H2-02, and H2-03 = 4 [Multi-Function Digital Output 1, Multi-Function Digital Output 2, and Multi-Function
Digital Output 3 = Alarm] will be ON.
• Use L8-05 [In PhaseLoss Selection] to enable and disable PF detection.
Code Name Causes Possible Solutions
PGo Encoder (PG) Feedback Loss
The encoder cable is disconnected or wired
incorrectly.
Examine for wiring errors or disconnected wires in the encoder
cable, and repair problems.
The encoder is not receiving power. Examine the encoder power supply.
The holding brake is stopping the motor. Release the holding brake.
Note:
• The drive detects this error if it does not receive the speed detection pulse signal from the encoder in the detection time set in F1-14 [Enc PGOpen Time for Detection].
• If the drive detects this error, the terminal assigned to H2-01, H2-02, and H2-03 = 4 [Multi-Function Digital Output 1, Multi-Function Digital Output 2, and Multi-Function
Digital Output 3 = Alarm] will be ON.
• If the drive detects this error, it will operate the motor as specified by the Stopping Method set in F1-02 [PGOpen Detection Select].
Code Name Causes Possible Solutions
PGoH Encoder (PG) Hardware Fault
The encoder cable is disconnected. Correct any disconnected wires in the encoder cable.
Note:
• If the drive detects this error, the terminal assigned to H2-01, H2-02, and H2-03 = 4 [Multi-Function Digital Output 1, Multi-Function Digital Output 2, and Multi-Function
Digital Output 3 = Alarm] will be ON.
• If the drive detects this error, it will operate the motor as specified by the Stopping Method set in F1-02 [PGOpen Detection Select].

qAL1 Q2pack Alarm
There was an error in the Q2pack program. Examine the Q2pack program and remove the cause of the error.
This is not a drive fault.
Note:
If the drive detects this error, the terminal assigned to H2-01, H2-02, and H2-03 = 4 [Multi-Function Digital Output 1, Multi-Function Digital Output 2, and Multi-Function
Digital Output 3 = Alarm] will be ON.
Code Name Causes Possible Solutions
qAL2 Q2pack Alarm 2
There was an error in the Q2pack program. Examine the Q2pack program and remove the cause of the error.
This is not a drive fault.
Note:
If the drive detects this error, the terminal assigned to H2-01, H2-02, and H2-03 = 4 [Multi-Function Digital Output 1, Multi-Function Digital Output 2, and Multi-Function
Digital Output 3 = Alarm] will be ON.
Code Name Causes Possible Solutions
qAL3 Q2pack Alarm 3
There was an error in the Q2pack program. Examine the Q2pack program and remove the cause of the error.
This is not a drive fault.
Note:
If the drive detects this error, the terminal assigned to H2-01, H2-02, and H2-03 = 4 [Multi-Function Digital Output 1, Multi-Function Digital Output 2, and Multi-Function
Digital Output 3 = Alarm] will be ON.

qAL4 Q2pack Alarm 4
There was an error in the Q2pack program. Examine the Q2pack program and remove the cause of the error.
This is not a drive fault.
Note:
If the drive detects this error, the terminal assigned to H2-01, H2-02, and H2-03 = 4 [Multi-Function Digital Output 1, Multi-Function Digital Output 2, and Multi-Function
Digital Output 3 = Alarm] will be ON.
Code Name Causes Possible Solutions
qAL5 Q2pack Alarm 5
There was an error in the Q2pack program. Examine the Q2pack program and remove the cause of the error.
This is not a drive fault.
Note:
If the drive detects this error, the terminal assigned to H2-01, H2-02, and H2-03 = 4 [Multi-Function Digital Output 1, Multi-Function Digital Output 2, and Multi-Function
Digital Output 3 = Alarm] will be ON.
Code Name Causes Possible Solutions
rUn Motor Switch during Run
The drive received a Motor 2 Selection [H1-xx =
61] during run.
Make sure that the drive receives the Motor 2 Selection while the
drive is stopped.
Note:
If the drive detects this error, the terminal assigned to H2-01, H2-02, and H2-03 = 4 [Multi-Function Digital Output 1, Multi-Function Digital Output 2, and Multi-Function
Digital Output 3 = Alarm] will be ON.
