6.4.1.2 Actual speed value
network output SNVT_lev_percent nvoDrvSpeed;
The output network variable indicates the current speed as proportion of the rated value. Display
value in [% ].
Output range
The possible bandwidth for the output variables is between –163.840% and 163.830% . Resolution:
0.005% .
The value +163.835% (7FFF
hex
) is assumed to be wrong.
Update rate
The variable is sent if the value changes or if the time set under Maximum Send Time ( nciSndHrtBt )
has expired.
The variable value will not be sent quicker than set in Minimum Send Time ( nciNinOutTm ).
Standard Service Type
The Standard Service Type is acknowledged.
Function
The value of nvoDrvSpeed results from the AIF output data word 1 of the process data channel.
Since 82XX and 93XX send different value, the actual speed values are converted in different ways.
82XX controllers send actual values in [Hz] and a factor of 50 (24000 = 480Hz).
The value for nvoDrvSpeed results from:
nvoDrvSpeed =
AIFOut.W1
nciNmlFreq
10 [ NVfactor]
× 50[ AIFfactor]
Ч 100[% ] Ч 200 [ NVfactor]
93XX controllers send actual values in [% ] and a factor of 163.83 (16383 = 100% ).
The value for nvoDrvSpeed results from:
nvoDrvSpeed =
AIFOut.W1
16383 [ NVfactor]
Ч 100[% ] Ч 200 [ NVfactor]
