8.1.8 Group 3.7: Prohibit Frequencies
In some systems it may be necessary to avoid certain
frequencies due to mechanical resonance problems.
By setting up prohibit frequencies it is possible to skip
these ranges. When the (input) frequency reference
is increased, the internal frequency reference is kept
at the low limit until the (input) reference is above the
high limit.

Multiplier of the currently
selected ramp time between
prohibit frequency limits.
8.1.9 Group 3.8: Supervisions
Choose here:
1. one or two (P3.8.1/P3.8.5) signal values for
supervision.
2. whether the low or high limits are supervised
(P3.8.2/P3.8.6)
3. the actual limit values (P3.8.3/P3.8.7).
4. the hystereses for the set limit values (P3.8.4/
P3.8.8).
