Drive errors

Fault elimination
Drive errors
Maloperation
Motor does not rotate
Motor does not rotate smoothly
Current consumption of motor
too high
156
Cause
DC−bus voltage too low
(red LED is blinking every 0.4 s;
keypad displays: LU)
Controller inhibited
(Green LED is blinking, keypad display: c)
Automatic start inhibited (C0142 = 0 or 2)
DC−injection braking (DCB) active
Mechanical motor brake is not released
Quick stop (QSP) active (keypad display: c)
Setpoint = 0
JOG setpoint activated and JOG frequency = 0 Select JOG setpoint
Fault active
Incorrect parameter set active
Operating mode C0014 = −4−, −5− set, but no
motor parameter identification
Assignment of several functions excluding
each other to one signal source 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
Motor cable defective
Maximum current set too low (C0022,
C0023)
Motor is under− or overexcited
C0084, C0087, C0088, C0089, C0090, C0091
and/or C0092 not adjusted to the motor data
Setting of C0016 too high
Setting of C0015 too low
l
Remedy
Check mains voltage
Deactivate controller inhibit,
controller inhibit can be set via
several sources
LOW−HIGH edge at X3/28
If necessary, correct starting
condition (C0142)
Deactivate DC injection brake
Manual or electrical release of
mechanical motor brake
Deactivate quick stop
Select setpoint
(C0037 ... C0039)
Eliminate fault
Change to correct parameter set via
terminal
Identify motor parameters (C0148)
Correct configuration in C0410
Jumper terminals
Check motor cable
Adjust settings to the application
Check parameter setting (C0015,
C0016, C0014)
Adjust codes manually or identify
motor parameters (C0148);
optimise vector control
Correct setting
Correct setting
