00
No error
01
Over-current
Immediate
switch-off
with inhibit
•
Short circuit output
•
Output switching
•
Motor too large
•
Faulty output stage
•
Rectify the short circuit
•
Switching with inhibited output
stage only
•
Connect a smaller motor
•
Consult SEW Service if the error
still cannot be reset
03
Ground fault
Immediate
switch-off
with inhibit
•
Ground fault in motor
•
Ground fault in inverter
•
Ground fault in the motor supply
lead
•
Overcurrent (see F-01)
•
Replace motor
•
Replace MOVITRAC
®

06
Phase failure in
supply system
(only applies
to 3-phase
inverter)
Immediate
switch-off
with inhibit
•
Phase failure
•
Supply voltage too low
•
Check the supply system lead
•
Check the supply voltage
07
DC link
overvoltage
Immediate
switch-off
with inhibit
•
DC link voltage too high
•
Ground fault
•
Extend deceleration ramps
•
Check supply cable to the braking
resistor
•
Check technical data of braking
resistor
•
Eliminate ground fault
08
Speed
monitoring
Immediate
switch-off
with inhibit
Current controller works at the set limit
due to:
•
Mechanical overload
•
Phase failure in supply system
•
Phase failure in motor
•
Reduce load
•
Increase deceleration time setting
P501
•
Check current limitation
•
Extend deceleration ramps
•
Check mains phases
•
Check motor cable and motor
Maximum speed for VFC operating
modes exceeded
•
Reduce maximum speed
10
ILLOP
Stop with
inhibit
•
Wrong command during command
execution
•
Incorrect conditions during
command execution
•
Function does not exist / is not
implemented in the inverter
•
Check the program
•
Check program run
•
Use another function
11
Overtempera-
ture
Stop with
inhibit
Thermal overload of inverter
•
Reduce load and / or ensure
adequate cooling
•
If a braking resistor is integrated in
the heat sink: Install braking
resistor externally
