Fault detection and elimination

Cause
DC-bus voltage too low
(Red LED is blinking every 0.4 s;
keypad display L L L L U U U U )
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
Defective motor cable
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

Faulty drive behaviour

Remedy
Check mains voltage
Remove the controller inhibit,
c 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
c
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)
