Please note:
For the "sensor" subsystem, a minimum speed must be exceeded within forced dynamisa-
tion.
The minimum speed depends on the ratio of the frequency at tracks AB "f
AB
" to the fre-
quency at track Z "f
Z
" in your configuration (fAB/fZ Verh. setting in the menu) and is calcu-
lated as follows:
} when fAB/fZ Verh. ≥ 1.0

At the very latest, a feasibility error will be detected when a tolerance expires. The toler-
ance level depends on the ratio of the frequency at tracks AB "f
