Troubleshooting
Memory locked
The program memory is write-protected and cannot be
altered.
This means that auto recognition can neither be set nor
deleted and programs can neither be saved nor deleted.
Equally, → RAM save and → Delete EPROM will not be
executed.
MCO 305 Operating Instructions
Error 191
Illegal cam array
An incorrect or old array is defined in the DIM instruction
for SETCURVE.
An old array may exist if the zbc (or cnf) file with all
parameters and arrays has not been loaded into the CAM-
Editor.
An incorrect array could be caused by the following:
Error 192
Encoder error
Error from encoder monitoring: open or short circuit in
accordance with the displayed LED.
An error will be indicated even if no encoder is connected.
Error 193
Stack overflow
Internal error. Dynamic stack overflow caused by too many
local variables or to many nested function calls.
Increase the stack size in Settings → Compiler.
Error 194
Out of dynamic memory
There is not enough dynamic memory for the requested
data log (TESTSETP). Either TESTSTART demands too much
dynamic memory or is called repeatedly.
Error 195
Too many testindices
The data logging command (TESTSETP) contained too
many indices. There is an actual limit of 20.
Error 196
Code too old
The compiler which produced the program code was too
old for this firmware. Please use a newer APOSS.
Error 198
Limit sw. violation
After reaching the limit switch and clearing the error there
was the attempt to move again into wrong direction.
Error 199
Internal MCO fault
If such an error should occur, please contact your dealer
and report the error number displayed to the technical
service department.

- It was not created by the curve editor.
- Previous version of a curve editor. Such an array
must first be converted by the current CAMEditor
(→ load and save).
- Or the order of the arrays in the DIM instruction
does not match the order in the zbc (or cnf) file.
Refer to the number of the array in the title bar
of the CAM-Editor in this respect.
