Motor does not rotate smoothly
Current consumption of motor
too high
Motor rotates, setpoints are 0"

Fault detection and elimination

Cause
DC−bus voltage too low
(Red LED is blinking every 0.4 s;
keypad display LU )
Controller inhibited
(Green LED is blinking, keypad display: c)
Automatic start inhibited (C0142 = 0 or 2)
DC injection brake active (DCB)
Mechanical motor brake is not released
Quick stop (QSP) active (keypad display: c) Remove quick stop
Setpoint = 0
JOG setpoint activated and JOG frequency =
0
Active fault
Wrong parameter set active
Control mode C0014 = −4−, −5−, but no motor
parameter identification
Under C0410 several functions which exclude
each other, are assigned to the same signal
source.
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
Defective motor cable
Maximum current set too low (C0022, C0023) Adaptation to the
Motor underexcited or overexcited
C0084, C0087, C0088, C0089, C0090, C0091
and/or C0092 are not adapted to the motor
data
Setting of C0016 too high
Setting of C0015 too low
C0084, C0087, C0088, C0089, C0090, C0091
and/or C0092 are not adapted to the motor
data
With the function j of the keypad a
setpoint has been selected.

Faulty drive behaviour

Remedy
Check mains voltage
Remove the controller
inhibit, controller inhibit
can be set through
several sources
LOW−HIGH signal at
X3/28
If necessary, correct start
condition (C0142)
Deactivate DC injection
brake
Manual or electrical
release of mechanical
motor brake
Setpoint selection
JOG setpoint selection
(C0037 ... C0039)
Eliminate fault
Change to correct
parameter set via
terminal
Motor parameter
identification (C0148)
Correct configuration in
C0410
Bridge terminals
Check motor cable
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" by
C0140 = 0
