Fault elimination
Drive errors
Maloperation Cause Remedy
Motor does not rotate DC−bus voltage too low
(red LED is blinking every 0.4 s;
keypad displays:
LU
)
Check mains voltage
Controller inhibited
(Green LED is blinking, keypad display:
)
Deactivate controller inhibit,
controller inhibit can be set via
several sources
Automatic start inhibited (C0142 = 0 or 2) LOW−HIGH edge at X3/28
If necessary, correct starting
condition (C0142)
DC−injection braking (DCB) active Deactivate DC injection brake
Mechanical motor brake is not released Manual or electrical release of
mechanical motor brake
Quick stop (QSP) active (keypad display: ) Deactivate quick stop
Setpoint = 0 Select setpoint
JOG setpoint activated and JOG frequency = 0 Select JOG setpoint
(C0037 ... C0039)
Fault active Eliminate fault
Incorrect parameter set active Change to correct parameter set via
terminal
Operating mode C0014 = −4−, −5− set, but no
motor parameter identification Identify motor parameters (C0148)
Assignment of several functions excluding
each other to one signal source in C0410 Correct configuration in C0410
Use of internal voltage source X3/20 for the
function modules Standard I/O, INTERBUS,
PROFIBUS−DP, or LECOM−B (RS485):
No jumper between X3/7 and X3/39 Jumper terminals
Motor does not rotate smoothly
Motor cable defective Check motor cable
Maximum current set too low (C0022,
C0023) Adjust settings to the application
Motor is under− or overexcited Check parameter setting (C0015,
C0016, C0014)
C0084, C0087, C0088, C0089, C0090, C0091
and/or C0092 not adjusted to the motor data Adjust codes manually or identify
motor parameters (C0148);
optimise vector control
Current consumption of motor
too high Setting of C0016 too high Correct setting
Setting of C0015 too low Correct setting
