Fault detection and elimination

Fault of the drive

Fault Cause
Motor does not
DC-bus voltage too low
rotate
(Red LED is blinking every 0.4 s;
keypad display
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 Motor does not
Defective motor cable

Maximum current set too low (C0022, C0023)
Motor underexcited or overexcited
