Troubleshooting and fault elimination

5.1 Malfunction of the drive
Fault Cause
Motor does not rotate DC−bus voltage too low
(Red LED is blinking every 0.4 s;
keypad display
Controller inhibited
(Green LED is blinking, keypad display:
Automatic start inhibited (C0142 = 0 or 2)
DC injection brake (DCB) active
Mechanical motor brake is not released
Quick stop (QSP) active (keypad display:
Setpoint = 0
JOG setpoint activated and JOG frequency = 0
Active fault
Wrong parameter set active
Operating mode C0014 = −4−, −5−, but no motor parameter identification
executed
Under C0410 several functions which exclude each other, are assigned
to the same signal source.
Use of internal voltage source X3/20 for function modules Standard I/O,
INTERBUS, PROFIBUS−DP or LECOM−B (RS485):
Jumper between X3/7 and X3/39 is missing
Motor does not rotate
Defective motor cable
smoothly
Maximum current set too low (C0022, C0023)
Motor underexcited or overexcited
C0084, C0087, C0088, C0089, C0090, C0091 and/or C0092 are not
adapted to the motor data
Current consumption of Setting of C0016 too high
motor too high
Setting of C0015 too low
C0084, C0087, C0088, C0089, C0090, C0091 and/or C0092 are not
adapted to the motor data
Motor rotates, setpoints are With the function

Remedy
Check mains voltage
Remove the controller inhibit, controller inhibit can be set
through several sources
LOW−HIGH edge at X3/28
If necessary, correct start condition (C0142)
Deactivate DC injection brake
Manual or electrical release of mechanical motor brake
Remove quick stop
Select setpoint
Select JOG setpoint (C0037 ... C0039)
Eliminate fault
Change to correct parameter set via terminal
Motor parameter identification (C0148)
Correct configuration in C0410
Jumper terminals
Check motor cable
Adapt settings to the application
Check parameter setting (C0015, C0016, C0014)
Manual adaptation or identification of motor parameters
(C0148)
Correct setting
Correct setting
Manual adaptation or identification of motor parameters
(C0148)
Set the setpoint to "0" via C0140 = 0
