Faults – Causes – Remedies
Faults that can be reset with the automatic restart function, after the cause has disappeared
These faults can also be reset by turning on and off or by means of a logic input or control bit ( [Fault reset] (rSF) parameter, page 174 ).
APF, CnF, COF, EPF1, EPF2, FCF2, LFF2, LFF3, LFF4, nFF, ObF, OHF, OLC, OLF, OPF1, OPF2, OSF, OtF1, OtF2, OtFL, PHF, PtF1,
PtF2, PtFL, SLF1, SLF2, SLF3, SPIF, SSF, tJF, and ULF faults can be inhibited and cleared remotely by means of a logic input or control
bit (
[Fault inhibit assign.] (InH) parameter, page 185 ).
Fault Name Probable cause Remedy
APF [Application fault]
• Controller Inside card fault • Please refer to the card documentation
CnF [Com. network] • Communication fault on
communication card
• Check the environment (electromagnetic compatibility)
• Check the wiring
• Check the time-out
• Replace the option card
• Inspect/repair the drive
COF [CAN com.] • Interruption in communication on the
CANopen bus
• Check the communication bus
• Check the time-out
• Refer to the CANopen User's Manual
EPF1 [External flt-LI/Bit] • Fault triggered by an external device,
depending on user
• Check the device, which caused the fault, and reset
EPF2 [External fault
com.] • Fault triggered by a communication
network
• Check for the cause of the fault and reset
FCF2 [Out. contact.
open.] • The output contactor remains open
although the closing conditions have
been met.
• Check the contactor and its wiring
• Check the feedback circuit
LCF
[input contactor] • The drive is not turned on even though
[Mains V. time out] (LCt) has elapsed.
• Check the contactor and its wiring
• Check the time-out
• Check the line/contactor/drive connection
LFF2
LFF3
LFF4
[AI2 4-20mA loss]
[AI3 4-20mA loss]
[AI4 4-20mA loss] • Loss of the 4-20 mA reference on
analog input AI2, AI3 or AI4
• Check the connection on the analog inputs
nFF [No Flow Fault] • Zero fluid • Check and rectify the cause of the fault.
• Check the zero fluid detection parameters page
168 .
ObF [Overbraking] • Braking too sudden or driving load • Increase the deceleration time
• Install a braking resistor if necessary
• Activate the
[Dec ramp adapt.] (brA) function, page 124 ,
if it is compatible with the application.
OHF
[Drive overheat] • Drive temperature too high • Check the motor load, the drive ventilation and the ambient
temperature. Wait for the drive to cool down before restarting
OLC
[Proc. Overload Flt] • Process overload • Check and remove the cause of the overload.
• Check the parameters of the
[PROCESS UNDERLOAD]
(OLd-) function, page 192 .
OLF
[Motor overload] • Triggered by excessive motor current • Check the setting of the motor thermal protection, check the
motor load. Wait for the drive to cool down before restarting
OPF1
[1 motor phase
loss] • Loss of one phase at drive output • Check the connections from the drive to the motor
