6.5.4 Network variable for 93XX controllers
Setpoint source selection
With 93XX controllers it is not possible to select a setpoint source by means of one code only. It is
however easy to adapt the controller to the drive task because it is working with preconfigured
function blocks which only have to be connected. For this it is not necessary to have special
programming skills.
The user himself can link the function blocks. It is however easier to use Lenze preconfigurations
which are already stored in the controller ROM. The Lenze preconfigurations (see code C0005)
determine the source (terminal, keypad, fieldbus module) which describes the frequency setpoint
and the control word.
The value in code C0005 must be set to ”xxx3” for LON bus operation (x = selected preconfiguration).
Fore more information please see the corresponding Manual and Operating Instructions for the
controller.
With the 93XX controller the process data assignment can be changed by reconfiguring the function
blocks AIF-IN and AIF-OUT.
Network variable from drive
•
nvoAIFStatus = STAT.B0 ... STAT.B15 (status word)
Status word
LOW byte HIGH byte
Bits 0 to 7 of the status word will be entered here. Bits 8 to 15 of the status word will be entered here (see chapter
6.5.4.1). The description of the bits can be obtained from the Code
Table.
•
nvoAifOut1 = AIF-OUT.W1
•
nvoAifOut2 = AIF-OUT.W2
•
nvoAifOut3 = AIF-OUT.W3
AIF-OUT.Wx
LOW byte HIGH byte
The actual frequency value with the signed normalisation 24000 = 480 Hz is provided here.
AIF-OUT.W1 to AIF-OUT.W3 depend on the signal configuration selected under L-C0005. For
detailed description of the 93XX signal configuration see the Operating Instructions for 93XX (only
the main configurations: 1000, 4000, 5000, etc.) or the Manual 93XX.
In the controller, other signals can be assigned to AIF-OUT.W1 to AIF-OUT.W3. For this, the
function-block configuration - described in the Manual 93XX - is used.
The function block AIF-OUT determines the controller output data as data interface for the 2141
fieldbus module.
