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
