Trouble Shooting & Fault Elimination
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 or serial control (see C01)
Start the controller via the remote
keypad or serial link
stP Output frequency = 0 Hz
(outputs U, V, W inhibited)
Setpoint = 0 Hz (C31 = 0) Setpoint selection
Quick stop activated through digital
input or serial link
Deactivate Quick stop
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
CL 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
controller is in
OFF or 1nh
Set terminal 28 to LOW or inhibit
by serial link
rC Remote keypad is active Attempt to use buttons on front of
controller
Buttons on front of controller are
disabled when remote keypad is
active
Error Cause Remedy (1)
cF
Data on EPM not valid
Data not valid for controller
• Use EPM providing valid data
• Load Lenze setting
CF Data error
GF OEM data not valid
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
Internal fault Please contact Lenze
FC3 Communication error Serial timer has timed out Check serial link connections
FC5 Communication error Serial communication failure Please contact Lenze
JF Remote keypad fault Remote keypad disconnected Check remote keypad connections
LC Automatic start inhibited c42 = 0 LOW-HIGH signal change at
terminal 28
5 Troubleshooting and fault elimination
(1) The drive can only be restarted if the error message has been reset; see c70
