Troubleshooting and fault elimination

9.1

Maloperation of the drive

Fault Cause
Motor does not
DC-bus voltage too low
rotate
(Red LED is blinking every 0.4 s;
keypad display LU )
Controller inhibited
(Green LED is blinking, keypad display:
Automatic start inhibited (C0142 = 0 or 2)
DC injection brake active (DCB)
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
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
Motor does not
Defective motor cable
rotate smoothly
Maximum current 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
Setting of C0016 too high
consumption of
Setting of C0015 too low
motor too high
C0084, C0087, C0088, C0089, C0090, C0091 and/or C0092 are not adapted to
the motor data
Motor rotates, With the function 
setpoints are

Maloperation of the drive
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
Setpoint selection
JOG setpoint selection (C0037 ... C0039)
Eliminate fault
Change to correct parameter set via terminal
Motor parameter identification (C0148)
Correct configuration in C0410
Jumper terminals
Check motor cable
Adaptation to 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
