Processing in case of an error
The module turns on Error detection signal
(X18), and reports the error "Outside the
stroke limit range at start" (error code: 83).
The module turns on Error detection signal
(X18), and reports the error "Positioning
address Outside the setting range" (error
code: 30).
The module turns on Error detection signal
(X18), and reports the error "Outside the
stroke limit range" (error code: 100).
