Fault Detection And Elimination; Malfunction Of The Drive - Lenze 8200 vector Instructions De Montage

Fault
Motor does not rotate
Motor does not rotate smoothly
Current consumption of motor
too high
Motor rotates, setpoints are 0"
L

Fault detection and elimination

Cause
DC−bus voltage too low
(Red LED is blinking every 0.4 s;
keypad display LU )
Controller inhibited
(Green LED is blinking, keypad display:
Automatic start inhibited (C0142 = 0 or 2)
DC injection brake (DCB) active
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
Operating mode C0014 = −4−, −5−, but no motor
parameter identification executed
Under C0410 several functions which exclude each
other, are assigned to the same signal source.
Use of internal voltage source X3/20 for function
modules Standard I/O, INTERBUS, PROFIBUS−DP or
LECOM−B (RS485):
Jumper between X3/7 and X3/39 is missing
Defective motor cable
Maximum current set too low (C0022, C0023)
Motor underexcited or overexcited
C0084, C0087, C0088, C0089, C0090, C0091
and/or C0092 are not adapted to the motor data
Setting of C0016 too high
Setting of C0015 too low
C0084, C0087, C0088, C0089, C0090, C0091
and/or C0092 are not adapted to the motor data
j
With the function of the keypad a setpoint
has been selected.

Malfunction of the drive

Remedy
Check mains voltage
Remove the controller inhibit, controller
c
inhibit can be set through several
)
sources
LOW−HIGH edge at X3/28
If necessary, correct start condition
(C0142)
Deactivate DC injection brake
Manual or electrical release of
mechanical motor brake
c
Remove quick stop
)
Select setpoint
Select JOG setpoint (C0037 ... C0039)
Eliminate fault
Change to correct parameter set via
terminal
Motor parameter identification (C0148)
Correct configuration in C0410
Jumper terminals
Check motor cable
Adapt settings to the application
Check parameter setting (C0015, C0016,
C0014)
Manual adaptation or identification of
motor parameters (C0148)
Correct setting
Correct setting
Manual adaptation or identification of
motor parameters (C0148)
Set the setpoint to "0" via C0140 = 0
