11.4.1 Maloperation of the drive
Fault Cause Remedy
Motor d oes not rotate DC-bus voltage too low
(Red LED is blinking ever y 0.4 s;
keypad display
LU)
Check mains voltage
Controller inhibited
(Green LED is blinking, keypad display:
c)
Remove the controller inhibit, controller inhibit can be set
through several sources
Automatic start inhibited (C0142 = 0 or 2) LOW-HIGH signal a t 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 selection
JOG setpoint activated and JOG frequency = 0 JOG setpoint selection (C0037 ... C0039)
Active fault Eliminate f ault
Wrong parameter set active Change to correct parameter set via terminal
Control mode C0014 = -4- , -5-, but no motor parameter identification Moto r paramete r identificati o n (C0148)
Unde r C0410 several functions, which exclude each other, are assigned
to 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
