Stop
Normally, if an error occurs, operation of FP0 stops.
The user may select whether operation is to be continued or stopped if a duplicate
output error or operation error occurs by setting the system registers.
11.1.1
Allowing Duplicated Output
When you change system register 20 settings (“ENAB”) using the programming
software, duplicated output is not regarded as an error and the FP0 continues to
operate.
11.1.2
Continuing After an Operation Error
When you change system register 26 settings (“CONT”) using the programming
software, the FP0 continues to operate. In this case, even if the FP0 continues to
operate, this is regarded as an error.
