O.ERR_18
SyncPos
Reset by CPU
Meaning
The processor has been stopped and a re-set
has automatically been executed (watchdog).
Cause
Short term voltage drop,
voltage peak or
short circuit.
O.ERR_19
SyncPos
User-Abort
Cause
The autostart-program has been aborted by the
user.
Or the CANCEL CANCEL CANCEL key was pressed during switching CANCEL
CANCEL
on and a Master Reset triggered.
O.ERR_25
SyncPos
Axis 1: Limit switch activated
Cause
A motion command has caused an axis limit switch
to be activated.
Tip
Through activation of a limit switch, the controller –
depending on the parameter ENDSWMOD (44) – is
automatically switched off and the drive must be
manually moved out of this position, before the error
message can be cleared.
O.ERR_51
SyncPos
Too many nested GOSUB commands
Cause
In the program, too many calls from one
subroutine to another subroutine exist.
The error usually occurs when there is a
recurrent reference to one of the sub-programs in
a sub-program.
Tip
Avoid too many (10 is maximum) opposing sub-
routine calls,
avoid subroutines which call themselves (re
cursive subroutine procedures).

VLT 5000 SyncPos option
O.ERR_52
SyncPos
Too many RETURN commands
Cause
There are either more RETURN than correspon-
ding GOSUB commands in the program, or there
is a direct jump from a subroutine with a GOTO
command.
Only one RETURN is allowed per sub-program.
It is always better to jump to the beginning of a
sub-program and then to jump with IF... to a pre-
viously defined label.
O.ERR_62
SyncPos
Error in verifying
Meaning
After saving something in the EEPROM (a program
or parameters) an error was detected during veri-
fication.
Tip
Delete the EEPROM with "CONTROLLER" →
"MEMORY" → "DELETE EEPROM" and try to
save the program or parameters again. If this is not
successful please call the technical service
department.
O.ERR_70
SyncPos
Error in DIM command
Meaning
The definition of an array in a DIM command does
not correspond to an already existing array in the
SyncPos option.
Cause
The fields are from older SyncPos programs. The
current program has other definitions.
Tip
Either adapt the SyncPos program to the correct
array size or delete the old arrays with
"CONTROLLER" → "MEMORY" → "DELETE
EEPROM".
NB!
Remember to follow the recommendations
concerning saving programs and parameters
before deleting the EEPROM.
