Name
Probable cause
Remedy
OPF2
[3 motor phase loss]
• Motor not connected or motor
power too low
• Output contactor open
• Instantaneous instability in the
motor current
• Check the connections from the drive to the motor
• If an output contactor is being used, parameterize

• Test on a low power motor or without a motor: In factory
settings mode, motor phase loss detection is active
[Output

[Yes]
(YES)
. To check the drive in
a test or maintenance environment, without having to use
a motor with the same rating as the drive (in particular for high
power drives), deactivate motor phase loss detection

OSF
[Mains overvoltage]
• Line voltage too high
• Disturbed line supply
• Check the line voltage
OtF1
[PTC1 overheat]
• Overheating of the PTC1 probes
detected
• Check the motor load and motor size
• Check the motor ventilation
• Wait for the motor to cool before restarting
• Check the type and state of the PTC probes
OtF2
[PTC2 overheat]
• Overheating of the PTC2 probes
detected
OtFL
[LI6=PTC overheat]
• Overheating of PTC probes
detected on input LI6
PtF1
[PTC1 probe]
• PTC1 probes open or short-
circuited
• Check the PTC probes and the wiring between them and the
motor/drive
PtF2
[PTC2 probe]
• PTC2 probes open or short-
circuited
PtFL
[LI6=PTC probe]
• PTC probes on input LI6 open or
short-circuited
SCF4
[IGBT short circuit]
• Power component fault
• Perform a test via the
[1.10 DIAGNOSTICS]
menu.
• Inspect/repair the drive
SCF5
[Motor short circuit]
• Short-circuit at drive output
• Check the cables connecting the drive to the motor, and the
motor’s insulation
• Perform tests via the
[1.10 DIAGNOSTICS]
menu.
• Inspect/repair the drive
SLF1
[Modbus com.]
• Interruption in communication on
the Modbus bus
• Check the communication bus
• Check the time-out
• Refer to the Modbus User's Manual
SLF2
[PowerSuite com.]
• Fault communicating with
PowerSuite
• Check the PowerSuite connecting cable
• Check the time-out
SLF3
[HMI com.]
• Fault communicating with the
graphic display terminal
• Check the terminal connection
• Check the time-out
SPIF
[PI Feedback]
• PID feedback below lower limit
• Check the PID function feedback.
• Check the PID feedback supervision threshold and time delay,

.
SSF
[Torque/current lim]
• Switch to torque limitation
• Check if there are any mechanical problems
• Check the parameters of
[TORQUE LIMITATION]
(tLA-)
page
155
and the parameters of the
[TORQUE OR I LIM. DETECT.]
(tId-)
fault, page

).
tJF
[IGBT overheat]
• Drive overheated
• Check the size of the load/motor/drive
• Reduce the switching frequency
• Wait for the motor to cool before restarting
ULF
[Proc. Underload Flt]
• Process underload
• Check and remove the cause of the underload.
• Check the parameters of the
[PROCESS OVERLOAD]
(ULd-)
function, page
