No.
Parameter Range Default
043 Switch Mode REL1
(switching condition for relay output)
:
0 |f| >= |Preselection|
Output switches in event of overspeed {S, H}
1 |f| <= |Preselection|
Output switches in event of underspeed {S, H, A}
2 |f| == |Preselection|
Output switches in event of leaving the
frequency band (Presel/- Hysteresis) {S, H, A}
3 Standstill (see parameter 056)
Output switches in event of standstill
4 f >= Preselection
Output switches in event of overspeed
May only be used with positive preselection
values! {S, H}
5 f <= Preselection
Output switches in event of underspeed
May only be used with positive preselection
values! {S, H, A}
6 f == Preselection
Output switches in event of leaving the
frequency band (Presel/- Hysteresis)
Only used with positive preselection values! {S, H, A}
7 f > 0
Output switches, if a positive frequency (e.g.
clockwise direction) is detected. The directional
information will be deleted immediately when
„standstill“(Parameter 056) is detected.
8 f < 0
Output switches, if a negative frequency (e.g.
anticlockwise direction) is detected. The
directional information will be deleted
immediately when „standstill“(Parameter 056)
is detected.


When using Switch Mode 2 or 6, a hysteresis is useful in order to avoid "bouncing" of
the outputs at the switching point.

When using Switch Mode 7 or 8, the specified standstill-time (see parameter 056) must
be higher than the adjusted wipe period (see parameter 044, ff.). This is helpful to
prevent a breakdown of the wipe signal before the wipe period has been elapsed.

With negative measuring values and presets a higher numerical value is smaller than
a lower numerical value, thus e. g. -1000 < -500.
