Fault Cause Remedy
Motor does not rotate
DC−bus voltage too low
(Red LED is blinking every 0.4 s;
keypad display
LU)
Check mains voltage
Controller inhibited
(Green LED is blinking, keypad display:
)
Remove the controller inhibit, controller
inhibit can be set through several
sources
Automatic start inhibited (C0142 = 0 or 2) LOW−HIGH edge at X3/28
If necessary, correct start condition
(C0142)
DC injection brake (DCB) active Deactivate DC injection brake
Mechanical motor brake is not released Manual or electrical release of
mechanical motor brake
Quick stop (QSP) active (keypad display: )
Remove quick stop
Setpoint = 0 Select setpoint
JOG setpoint activated and JOG frequency = 0 Select JOG setpoint (C0037 ... C0039)
Active fault Eliminate fault
Wrong parameter set active Change to correct parameter set via
terminal
Operating mode C0014 = −4−, −5−, but no motor
parameter identification executed
Motor parameter identification (C0148)
Under C0410 several functions which exclude each
other, are assigned to the same signal source.
Correct configuration in C0410
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
Jumper terminals
Motor does not rotate smoothly
Defective motor cable Check motor cable
Maximum current set too low (C0022, C0023) Adapt settings to the application
Motor underexcited or overexcited Check parameter setting (C0015, C0016,
C0014)
C0084, C0087, C0088, C0089, C0090, C0091
and/or C0092 are not adapted to the motor data
Manual adaptation or identification of
motor parameters (C0148)
Current consumption of motor
too high
Setting of C0016 too high Correct setting
Setting of C0015 too low Correct setting
C0084, C0087, C0088, C0089, C0090, C0091
and/or C0092 are not adapted to the motor data
Manual adaptation or identification of
motor parameters (C0148)
Motor rotates, setpoints are 0"
With the function of the keypad a setpoint
has been selected.
Set the setpoint to "0" via C0140 = 0
