7.1.8
Group 3.7: Prohibit Freq
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.
7.1.9
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).
