4.3.3 Connection of the speed measuring unit
You can select the speed measuring units. They all can be retrofitted. The speed measuring units
are delivered with connection cables. They are connected according to the user’s application or to
the requirements of the Lenze display units.
Three-phase AC tacho with rectification
The three-phase AC tacho with rectification generates a voltage which depends on the speed and
the input resistance of the evaluating unit. The generated voltage can be evaluated via a
superimposed control or Lenze display units.
Suitable Lenze display units:
Analog voltmeter VSC 96 (approx. 5000
Ω
)
Digital voltmeter Fdi 635-F (> 100 k
Ω
)
