• For a 1-encoder system, encoder faults are detected using different hardware and
• Stop function category 0 to EN 60204-1:2006 (STO or STOP A to Safety Integrated)
• Safety Integrated functions cannot detect parameterization errors made by the machine
• Motor Modules or the motor must be replaced with a device of the same type, as the
If an internal or external fault occurs, none or only some of the parameterized safety
functions are available during the STOP-F response triggered by the fault. This must be
taken into account when a delay time between STOP F and STOP B is parameterized.
This applies in particular to vertical axes.
