8-454 SINUMERIK 840D/SIMODRIVE 611 digital SINUMERIK Safety Integrated (FBSI) - Edition 11.03
Alarm number 411101
Meaning: Parameter, axis not in the permissible range
Remedy: Use the permissible axis number
Note
The user program must call the block. The user must provide an instance DB
with any number for this purpose. The call is multi-instance-capable.
