No. RemedyCauseMeaningDisplay

125 CE14 FIF−CAN BUS−OFF status

(too many faulty telegrams

received)

PLC has received too many faulty telegrams sent

via system bus and has disconnected itself from

the bus

 Check wiring/cable

 Check bus termination (if any)

 Check screen contact of the cables

 Check PE connection

 Check bus load

 Reduce baud rate (observe cable length)

Task with Id.9

Time−out (see task configuration):

Task processing takes longer than the monitoring

time set

 Set task run−time

 If necessary, change monitoring time

 Determine time−out reason by checking the

task run−times at the task monitor

 Swap out time−critical program parts to a

slower task

209 FLOAT SYS−T System task

Floating−point error (REAL):

Error in real calculation (e.g. divided by 0)

 Check real calculation (program code)

 The error is eliminated as in a task overflow

cyclic task (PLC_PRG)

Task processing takes longer than the monitoring

time set

 Set task run−time

 If necessary, change monitoring time

 Determine time−out reason by checking the

task run−times at the task monitor

 Swap out time−critical program parts to a

slower task

220 NoT−FKT−CREDIT Insufficient units on the target

system

It was tried to load a program with technology

functions to a PLC not providing corresponding

units

Use the T−variant of the PLC

230 No Program PLC program error No PLC program loaded Load PLC program to PLC

231 Unallowed Lib Library function is not

supported

You have called a library function in the PLC

program. This function is not supported, e.g.

because the required hardware is not available

Remove library function or ensure that the

required hardware devices are provided

232 NoCamData Motion profiles (cam data) are

not available

When functions of the LenzeCamControl.lib

function library were called, the controller

recognised that there are no motion profiles (cam

data) loaded in the PLC memory

 Ensure that valid cam data were attached to

the project via the DDS cam support

 Re−load the PLC program (maybe the

OnlineWReset (original) command has been

executed in DDS)

240 ovrTransQueue Error Free CAN objects" Overflow of send order memory  Reduce number of send orders

 Prolong cycle time

241 ovr Receive Error Free CAN objects" Too many receive telegrams Reduce number of telegrams on bus

250 2.Flash Err Error during FLASH memory

access

The PLC program tries to access a faulty FLASH

memory or FLASH memory does not exist

Ensure that the PLC has a FLASH memory. If

FLASH memory already exists, contact Lenze.

251 AddData CsErr Error during FLASH memory

access

Check sum error occurred when loading data into

the FLASH memory

Check the check sum of the file to be loaded and

repeat data transfer

252 AddData DlErr Error during FLASH memory

access

Error occurred when downloading data into the

FLASH memory (e.g. time−out, transmission error,

mains failure during data transfer)

Check/repeat data transfer

260 Err NodeGuard "Life guarding event" PLC has been configured as a CAN slave with

"node guarding" and has not received any "node

guarding" telegram within the node lifetime of the

CAN master.

 Check system bus (CAN) and CAN configuration

 Ensure that "node guarding" has been

activated in the CAN master

 Adapt node lifetime to CAN master setting
