The main circuit capacitors have become
unserviceable.
•
Examine the capacitor maintenance time in monitor
U4-05
[CapacitorMaintenance]
.
•
If
U4-05
is more than 90%, replace the capacitor. Contact
Yaskawa or your nearest sales representative for more
information.
•
Examine the supply voltage for problems.
•
Re-energize the drive.
•
If the alarm stays, replace the circuit board or the drive. Contact
Yaskawa 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 to H2-03 = 10 [MFDO Function Select = Alarm]
will be ON.
•
Use
L8-05 [Input Phase Loss Protection Sel]
to enable and disable
PF
detection.

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 [Encoder Open-Circuit Detect Time]
.
•
If the drive detects this error, the terminal assigned to
H2-01 to H2-03 = 10 [MFDO Function Select = 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 [PG Open Circuit Detection Select]
.

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 set to
H2-01 to H2-03 = 10 [MFDO Function Select = Alarm]
will activate.
•
Parameters
F1-20 [Encoder 1 PCB Disconnect Detect]
or
F1-36 [Encoder 2 PCB Disconnect Detect]
enable and disable
PGoH
detection.
•
If the drive detects this error, it will operate the motor as specified by the stopping method set in
F1-02 [PG Open Circuit Detection Select]
.

rUn
Motor Switch during Run
The drive received a
Motor 2 Selection [H1-xx = 16]
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 to H2-03 = 10 [MFDO Function Select = Alarm]
will be ON.

SE
Modbus Test Mode Error
MEMOBUS/Modbus communications self-
diagnostics
[H1-xx = 67]
was done while the drive
was running.
Stop the drive and do MEMOBUS/Modbus communications self-
diagnostics.
Note:
If detected, the terminal assigned to
H2-01 to H2-03 = 10 [MFDO Function Select = Alarm]
will be ON.

STo
Safe Torque OFF
Safe Disable inputs H1-HC and H2-HC are open.
•
Make sure that the Safe Disable signal is input from an external
source to terminal H1-HC and H2-HC.
•
When the Safe Disable function is not in use, use a jumper to
connect terminals H1-HC and H2-HC.
There is internal damage to the two Safe Disable
channels.
Replace the board or the drive. Contact Yaskawa or your nearest
sales representative to replace the board.
Note:
•
The drive will not output an alarm signal for this alarm.
•
If the drive detects this error, the terminal set to
H2-01 to H2-03 = 21 [MFDO Function Select = Safe Torque OFF]
will activate.

SToF
Safe Torque OFF Hardware
One of the two terminals H1-HC or H2-HC received
the Safe Disable input signal.
The Safe Disable input signal is wired incorrectly.
•
Make sure that the Safe Disable signal is input from an external
source to terminals H1-HC or H2-HC.
•
When the Safe Disable function is not in use, use a jumper to
connect terminals H1-HC and H2-HC.
There is internal damage to one Safe Disable channel.
Replace the board or the drive. Contact Yaskawa or your nearest
sales representative to replace the board.
Note:
If the drive detects this error, the terminal set to
H2-01 to H2-03 = 10 [MFDO Function Select = Alarm]
will activate.
