R-DNE
Remote Drive Disable
•
The digital input set to
H1-xx = BD [MFDI
Function Selection = Remote Drive Disable]
activated.
•
The digital input set to
H1-xx = 1BD [!Remote
Drive Disable]
deactivated.
Examine the statuses of the digital input terminals set to
H1-xx =
BD or 1BD
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.
SPCNR
Single Phase Converter Not Ready
When
YC-14 = 1 [Behavior when SPC is Not Ready
= Coast to Stop - Alarm]
, the digital input set to
H1-
xx = BE [MFDI Function Selection = Single Phase
Converter Ready NC]
deactivated to show that the
attached converter is faulted or not ready.
•
Examine the wiring between the drive and converter.
•
Examine the error code on converter.
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 performance life estimate.
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.
UL6
Underload or Belt Break Detected
The output current decreased less than the motor
underload curve set in
L6-14 [Motor Underload Level
@ Min Freq]
for longer than the time set in
L6-03
[Torque Detection Time 1]
.
The belt has broken disconnecting the motor from the
load.
Examine parameters
L6-13 [Motor Underload Curve Select]
and
L6-14
.
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
.
