3.5 Analog – interface, basic functionalities
3.5.1 Measuring system version with Analog-Voltage
Over the analog interface the measuring system position or speed can be output as
voltage value. The used acronyms in the formula are summarized in the legend on the
following page.
Analog 0…+10 VDC
Analog -10…+10 VDC
Analog Voltage / Position
Count direction:
Increasing
1)
Note the sign!
Pos =
(U
O
– U
SV
) * (Pos
FV
– Pos
SV
)
+ Pos
SV
(U

1)
Changing the parameter Counting direction, see chapter 4.1.1, changes also the
direction of the analog values and inverts the current counting direction at the
analog output (increasing --> decreasing or decreasing --> increasing)
Analog Voltage / Speed
Count direction:
Increasing
2)
Note the sign!
n =
(U

– U
SV
) * (n
FV
– n
SV
)
+ n

– U
SV

Changing the parameter Counting direction, see chapter 4.1.1, changes the sign of
the speed "n".
