Fault Detection And Elimination; Faulty Drive Behaviour - Lenze 8200 motec 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:
c)
Automatic start inhibited
(C0142 = 0 or 2)
DC injection brake active (DCB)
Mechanical motor brake is not released Manual or electrical release of
Quick stop (QSP) active (keypad display:
c)
Setpoint = 0
JOG setpoint activated and JOG
frequency = 0
Active fault
Wrong parameter set active
Control mode C0014 = −4−, −5−, but no
motor parameter identification
Under C0410 several functions which
exclude each other, are assigned to the
same signal source.
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
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
With the function j of the keypad a
setpoint has been selected.

Faulty drive behaviour

Remedy
Check mains voltage
Remove the controller inhibit,
controller inhibit can be set
through several sources
LOW−HIGH signal at X3/28
If necessary, correct start
condition (C0142)
Deactivate DC injection brake
mechanical motor brake
Remove quick stop
Setpoint selection
JOG setpoint selection
(C0037 ... C0039)
Eliminate fault
Change to correct parameter
set via terminal
Motor parameter identification
(C0148)
Correct configuration in C0410
Bridge terminals
Check motor cable
Adaptation 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" by
C0140 = 0
