Troubleshooting and fault elimination

Troubleshooting

Maloperation
Motor does not rotate
Motor does not rotate smoothly
Current consumption of motor
too high
EDK82MV371 DE/EN/FR 7.0
Troubleshooting and fault elimination
Cause
DC−bus voltage too low
(red LED is blinking every 0.4 s;
keypad displays: LU)
Controller inhibited
(Green LED is blinking, keypad display:
c)
Automatic start inhibited (C0142 = 0
or 2)
DC−injection braking (DCB) active
Mechanical motor brake is not
released
Quick stop (QSP) active (keypad
display: c)
Setpoint = 0
JOG setpoint activated and JOG
frequency = 0
Fault active
Incorrect parameter set active
Operating mode C0014 = −4−, −5− set,
but no motor parameter identification
Assignment of several functions
excluding each other to one signal
source in C0410
Use of internal voltage source X3/20
for the function modules Standard
I/O, INTERBUS, PROFIBUS−DP, or
LECOM−B (RS485):
No jumper between X3/7 and X3/39
Motor cable defective
Maximum current set too low (C0022,
C0023)
Motor is under− or overexcited
C0084, C0087, C0088, C0089, C0090,
C0091 and/or C0092 not adjusted to
the motor data
Setting of C0016 too high
Setting of C0015 too low
C0084, C0087, C0088, C0089, C0090,
C0091 and/or C0092 not adjusted to
the motor data

Troubleshooting
Remedy
Check mains voltage
Deactivate controller inhibit,
controller inhibit can be set
via several sources
LOW−HIGH edge at X3/28
If necessary, correct starting
condition (C0142)
Deactivate DC injection brake
Manual or electrical release of
mechanical motor brake
Deactivate quick stop
Select setpoint
Select JOG setpoint
(C0037 ... C0039)
Eliminate fault
Change to correct parameter
set via terminal
Identify motor parameters
(C0148)
Correct configuration in
C0410
Jumper terminals
Check motor cable
Adjust settings to the
application
Check parameter setting
(C0015, C0016, C0014)
Adjust codes manually or
identify motor parameters
(C0148); optimise vector
control
Correct setting
Correct setting
Adjust codes manually or
identify motor parameters
(C0148); optimise vector
