Standstill indication
—
The open
collector
transistor
used
tor
the standstill
lndication
function opens,
when, during
the deceleration
phase,
the pre—programmed frequency
is
reached.
The transistor
remains
open,
until
the trequency f
=
0Hz Is
attained.
The minimum swltch-on tiine of
the
transistor is
lOOms.

-
The Open-Ccllector transistor
for the „frequency identical“
indication
switches,
when
a programmed
freguency of
the acceleration and
deceleration phase is reached.
The transistor
is eriabled, until
the rotational field freguency is
identical with the compared treguericy
or the acceleration/deceleration
phase is not yet finished. The
minimum switching tlme of the
transistor Is lOOms.
(The signal can be used e.g.
tor
switching ot the aoceleratlon/
deceleration ramp).
