Conversion formulae

The following values are used as factors and divisors for the below-mentioned conversion formulae

depending on the function selected in

C01354/1

:

Alternatively, a scaling can be carried out in the form 2

x

.

• The value for x can be set in

C01353/1

.

• In the Lenze setting "0", no scaling takes place (2

0

= 1).
