122 YASKAWA TOEPC71061737B GA800 Drive Installation & Primary Operation
Code Name Causes Possible Solutions
PGoH Encoder (PG) Hardware Fault
The encoder cable is disconnected. Correct any disconnected wires in the encoder cable.
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.
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.
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.
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.
TiM Keypad Time Not Set
There is a battery in the keypad, but you have not set
the date and time.
Use the keypad to set the date and time.
TrPC IGBT Maintenance Time (90%)
The IGBT is at 90% of its expected performance life. Replace the IGBT or the drive. For more information, contact
Yaskawa or your nearest sales representative.
UL3 Undertorque Detection 1
A fault occurred on the machine.
Example: There is a broken pulley belt.
Examine the machine and remove the cause of the fault.
UL4 Undertorque Detection 2
A fault occurred on the machine.
Example: There is a broken pulley belt.
Examine the machine and remove the cause of the fault.
UL5 Mechanical Weakening Detection 2
The drive detected undertorque as specified by the
conditions for mechanical weakening detection set in
L6-08 [Mechanical Fatigue Detect Select].
Examine the machine for deterioration.
Uv Undervoltage
The drive input power voltage is changing too much. • Examine the input power for problems.
• Make the drive input power stable.
• If the input power supply is good, examine the magnetic
contactor on the main circuit side for problems.
◆ Parameter Setting Errors
Parameter setting errors occur when multiple parameter settings do not agree, or when parameter setting values are
not correct. Refer to the table in this section, examine the parameter setting that caused the error, and remove the
cause of the error. You must first correct the parameter setting errors before you can operate the drive. The drive will
not send notification signals for the faults and alarms when these parameter setting errors occur.
Code Name Causes Possible Solutions
oPE01 Drive Capacity Setting Error
The value set in o2-04 [Drive Model (KVA) Selection]
does not agree with the drive model.
Set o2-04 to the correct value.
oPE02 Parameter Range Setting Error
Parameters settings are not in the applicable setting
range.
1. Push to show U1-18 [oPE Fault Parameter], and find
parameters that are not in the applicable setting range.
2. Correct the parameter settings.
Note:
If more than one error occurs at the same time, other oPExx
errors have priority over oPE02.
oPE03 Multi-Function Input Setting Err
The settings for these parameters do not agree:
• F3-10 to F3-25 [Terminal D1 to DF Function
Selection]
• H1-01 to H1-08 [Terminals S1 to S8 Function
Selection]
• H7-01 to H7-04 [Virtual Multi-Function Inputs 1
to 4]
Correct the parameter settings.
oPE05 Run Cmd/Freq Ref Source Sel Err
The setting to assign the Run command or frequency
reference to an option card or the pulse train input is
incorrect.
Correct the parameter settings.
oPE06 Control Method Selection Error
A1-02 = 1, 3, or 7 [Control Method Selection = CL-
V/f, CLV, CLV/PM] is set, but there is no encoder
option card connected to the drive.
• Connect an encoder option card to the drive.
• Set A1-02 correctly.
