Fault elimination

Drive errors

Malfunction
Motor does not rotate
Motor does not rotate smoothly
Current consumption of motor
too high
EDK82EV113 DE/EN/FR 11.0
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 displays: c)
Automatic start inhibited (C0142 = 0 or 2)
DC−injection braking (DCB) active
Mechanical motor brake is not released
Quick stop (QSP) active (keypad displays: c) Deactivate quick stop
Setpoint = 0
JOG setpoint activated and JOG frequency = 0 Select JOG setpoint
Active fault
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

Fault elimination
Drive errors
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
Select 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);
