De te cte d Fault Nam e Probable cause Re m e dy
OPF2 [3 m otor phase los s]
•
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, set
[Output Phas e Los s ] (OPL) to [Output cut] (OAC) , page
256 .
•
Test on a low pow er motor or w ithout a motor: In factory
settings mode, motor phase loss detection is active
[Output Phas e Loss] (OPL) = [Ye s ] (YES) . To check the
drive in a test or maintenance environment, w ithout having to
use a motor w ith the same rating as the drive (in particular for
high pow er drives), deactivate motor phase loss detection
[Output Phas e Loss]
(OPL) =
[No]
(nO) , see instructions
given page 256 .
•
Check and optimize the follow ing parameters:

(UnS) and
[Rated mot. curre nt ]
(nCr) page 86 and
perform [Auto tuning] (tUn) page 87 .
OSF [M ains overvoltage]
•
Supply voltage too high.
•
Disturbed mains supply.
•
Check the supply voltage.
OtFL [LI6=PTC ove rheat] •
Overheating of PTC probes detected
on input LI6.
•
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.
PtFL [LI6=PTC probe] •
PTC probe on input LI6 open or
short-circuited.
•
Check the PTC probe and the w iring betw een it and the
motor/drive.
SCF1 [M otor s hort circuit] •
Short-circuit or grounding at the drive
output.
•
Check the cables connecting the drive to the motor, and the
motor insulation.
• Reduce the sw itching frequency.
•
Connect chokes in series w ith the motor.
•
Check the adjustment of speed loop and brake.
•
Increase the [Time to restart ] (ttr) , page 101 .
• Increase the sw itching frequency.
SCF3
[Ground short
circuit] •
Significant earth leakage current at
the drive output if several motors are
connected in parallel.
•
Check the cables connecting the drive to the motor, and the
motor insulation.
•
Reduce the sw itching frequency.
• Connect chokes in series w ith the motor.
•
Check the adjustment of speed loop and brake.
•
Increase the [Time to restart ] (ttr) , page 101 .
•
Reduce the sw itching frequency.
SCF4 [IGBT s hort circuit] • Pow er component detected fault. • Contact BLEMO Product Support.
SCF5
[M otor s hort circuit] •
Short-circuit at drive output.
•
Check the cables connecting the drive to the motor, and the
motor’s insulation.
•
Contact BLEMO Product Support.
SLF1
[M odbus com.] •
Communication interruption on the
Modbus bus.
•
Check the communication bus.
•
Check the time-out.
•
Refer to the Modbus User's manual.
SLF2 [PC com .]
•
Communication interruption w ith PC
Softw are.
•
Check the PC Software connecting cable.
•
Check the time-out.
SLF3 [HM I com .] •
Communication interruption w ith the
graphic display terminal or remote
display terminal.
•
Check the terminal connection
• Check the time-out.
SSF [Torque/current lim ] • Sw itch to torque or current limitation. • Check if there are any mechanical problems.
•
Check the parameters of
[TORQUE LIM ITATION]
(tOL-)
page 216 and the parameters of the
[TORQ U E OR I LIM. DETE C T.] (tId-) , page 264 .
tJF
[IGBT ove rheat] •
Drive overheated.
•
Check the size of the load/motor/drive.
•
Reduce the sw itching frequency.
•
Wait for the motor to cool before restarting.
