Standstill indication

The open

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

-

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).
