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
