8.3 Fault indications

Display Fault
--- No fault
EEr External fault (TRIP-Set)
H05 Internal fault
LU Undervoltage
OC1 Short circuit
OC2 OC2 Earth fault Earth fault
OC3 Overload inverter during
acceleration or short acceleration or short
circuit circuit
OC4 Overload controller during
deceleration

OC6 Overload motor
Troubleshooting and fault elimination
Cause
-
A digital input assigned to the
TRIP-Set function has been
activated
DC-bus voltage too low
Short circuit
Excessive capacitive charging
current of the motor cable
Grounded motor phase
Excessive capacitive charging
current of the motor cable
Acceleration time too short
(C012)
Defective motor cable
Interturn fault in the motor
Deceleration time too short
(C013)
Frequent and too long
acceleration processes with
overcurrent
Permanent overload with
I > 1.05 x I
motor Nx
Motor is thermally overloaded, for
instance, because of
-
impermissible continuous
current
-
frequent or too long
acceleration processes
Remedy
-
Check external encoder
Contact Lenze
-
Check mains voltage
-
Check supply module
Find out cause of short circuit; check
cable
Use motor cable which is shorter or of
lower capacitance
Check motor; check cable
Use motor cable which is shorter or of
lower capacitance
-
Increase acceleration time
-
Check drive selection
Check wiring
Check motor
-
Increase deceleration time
-
Check the selection of the brake
resistor or connect the brake
chopper
Check drive dimensioning
-
Check drive selection
-
Check the setting under C120
