Maloperation of the drive
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:
c
)
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 active (DCB)
Deactivate DC-injection brake
Mechanical motor brake is not released
Manual or electrical release of mechanical motor brake
Quick stop (QSP) active (keypad display:
c
)
Remove quick stop
Setpoint = 0
Setpoint selection
JOG setpoint activated and JOG frequency = 0
JOG setpoint selection (C0037 ... C0039)
Active fault
Eliminate fault
Wrong parameter set active
Change to correct parameter set via terminal
Control mode C0014 = -4-, -5-, but no motor parameter identification
Motor parameter identification (C0148)
Under C0410 several functions, which exclude each other, are assigned to the
same signal source.
Correct configuration in C0410
Use internal voltage source X3/20 for function modules Standard-I/O, INTERBUS,
PROFIBUS-DP or LECOM-B (RS485):
Bridge between X3/7 and X3/39 is missing
Jumper terminals
Motor does not
Defective motor cable
Check motor cable
Motor does not
rotate smoothly
Maximum current too low (C0022, C0023)
Adaptation to application
rotate smoothly
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

Current
Setting of C0016 too high
Correct setting
Current

Setting of C0015 too low
Correct setting

motor too high
C0084, C0087, C0088, C0089, C0090, C0091 and/or C0092 are not adapted to
the motor data
Manual adaptation or identification of motor parameters

Motor rotates,
setpoints are

of the keypad a setpoint has been selected.
Set the setpoint to ”0” by C0140 = 0
