3 Troubleshooting and fault elimination
3.1 Maloperation of the drive
Fault Cause Remedy
Motor d oes 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, keypa d 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 select ion
JOG setpoint activated and JOG frequency = 0 JOG setpoint selection (C0037 ... C0039)
Active fault Eliminat e fault
Wrong parameter set active Change to correct parameter set via terminal
Control mode C0014 = -4- , -5-, but no motor parameter identification Motor parame ter identification (C0148)
Under C0410 several functions, which e xclude ea ch other, are a ssigned t o 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
