CAUTION!
If there are frequency differences between tracks A and B of the
incremental encoder and/or between the proximity switches on
inputs I10 (I20) and I11 (I21), the PNOZmulti switches to a safe
condition if a frequency exceeds the configured standstill fre-
quency. If the speed monitor detects different rotation direc-
tions, note the following:
` With version 1.X devices the PNOZmulti changes to STOP.
` With devices from version 2.0, the axis in question changes to
the safe condition. The safe condition is cleared again as soon
as the error is remedied. Hazards that can arise through an au-
tomatic restart must be excluded from the application program.
