MCO 305 Operating Instructions
Error 118
Reset by CPU
The processor has been stopped and a re-set has
automatically been executed (watchdog).
Causes could be
Short term voltage drop,
voltage peak, or
short circuit.
Error 119
User abort
The Autostart program has been aborted by the
user.
Or the [CANCEL] key was pressed during switching
on and a Master Reset triggered.
Error 125
HW end limit
A motion command has caused an axis limit switch
to be activated.
Through activation of an end limit switch, the con-
troller (depending on the par. 33-40 ENDSWMOD)
is automatically switched off and the drive must be
manually moved out of this position, before the
error message can be cleared.
Error 149
Too many inter.
More interrupt functions than the maximum
possible number were used. Permitted are:
32 ON INT
32 ON STATBIT
32 ON COMBIT
10 ON PARAM
20 ON APOS, ON MAPOS, ON MCPOS
Error 150
No ext. 24V
External supply is missing.
Error 151
Too many gosub
In the program exists too many calls from one
subroutine to another subroutine.
The error usually occurs when there is a recurrent
reference to one of the sub-programs in a sub-
program.

__ Troubleshooting __
Avoid too many (10 is maximum) opposing subrou-
tine calls, and avoid subroutines which call them-
selves (re-cursive subroutine procedures).
Error 152
Too many return
There are either more RETURN than corresponding
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.
Error 154
D. out overload
Digital output overloaded.
Error 155
LINK failed
LINKGPAR command failed.
Error 162
Memory error
After saving something in the EEPROM (a program
or parameters) an error was detected during verifi-
cation.
Delete the EEPROM with a 3-finger reset and try to
save the program or parameters again.
If this is not successful please call the technical
service department.
Error 170
Array size (DIM)
The definition of an array in a DIM command does
not correspond to an already existing array in the
MCO 305.
Cause might be that the fields are from older
SYNCPOS/APOSS programs. The current program
has other definitions.
Either adapt the APOSS program to the correct
array size or delete the old arrays.

NB!:
Remember to follow the recommendations
concerning saving programs and
parameters before deleting the EEPROM.
