Troubleshooting and fault elimination
(1) The drive can only be restarted if the error message has been reset; see c70
Status
Cause
Remedy
e.g.
50.0
Present output frequency
Trouble free operation
OFF
Stop (outputs U, V, W inhibited)
LOW signal at terminal 28
Set terminal 28 to HIGH
1nh
Inhibit (outputs U, V, W inhibited)
Controller is set up for remote
keypad (see C01)
Start the controller via the remote
keypad
stP
Output frequency = 0 Hz
(outputs U, V, W inhibited)
Quick stop activated through digital
input
Deactivate Quick stop
FSt
Flying restart attempt
c42 = 2, 3
br
DC-injection brake active
DC-injection brake activated
• via digital input
• automatically
Deactivate DC-injection brake
• digital input = LOW
• automatically after holding time c06
has expired
CAL
Motor calibration is in process
c48 = 1 and terminal 28 = HIGH
Only perform the motor calibration
when C14 = 4...7
CL,FCL
Current limit reached
Controllable overload
Automatically (see C22)
LU
Undervoltage on DC bus
Mains voltage too low
Check mains voltage
dEC
Overvoltage on DC bus during
deceleration (warning)
Excessively short deceleration time
(C13, c03)
Automatically if overvoltage
< 1 s,
OU
, if overvoltage > 1 s
nEd
No access to code
Can only be changed when the control-
ler is in
OFF
or
1nh
Set terminal 28 to LOW
rC
Remote keypad is active
Attempt to use buttons on front of
controller
Buttons on front of controller are dis-
abled when remote keypad is active
Error
Cause
Remedy
(1)
Ad
A/D converter error
Please contact Lenze
bF
Identification fault
C93 value stored on EPM does not
match controller model
• Use EPM providing valid data
• Load Lenze setting
cF
Data on EPM not valid
Data not valid for controller
CF
Data error
GF
OEM data not valid
LC
Automatic start inhibited
c42 = 0, 2
LOW-HIGH signal change at terminal 28
F1
EPM error
EPM missing or defective
Power down and replace EPM
CFG
Digital inputs not
uniquely assigned
E1...E3 assigned with the same digital
signals
Each digital signal can only be used
once
Either just “UP” or “DOWN” used
Assign the missing digital signal to a
second terminal
dF
Dynamic braking fault
Dynamic braking resistors are
overheating
Increase deceleration time
EEr
External error
Digital input “TRIP set” is active
Remove external error
FC5,
F2
...
F0
Internal fault
