6.5.2 Network variable for 82XX controllers
Setpoint source selection
The setpoint source for these controllers is selected under code C0001. An evaluation of process
data is only possible if code C0001 is set to ”3” when the controller is operated together with the
fieldbus module.
Therefore the process data channel serves as setpoint source, describing the frequency setpoint
(C0046) and the control word (parameter channel, C0135) (see Operating Instructions 82XX).
Tip!
Please observe that code C0001 is available in all parameter sets.
Network variable from drive
•
nvoAIFStatus reads the status word ( ^ 6-38)
Status word
LOW byte HIGH byte
Bits 0 to 7 of the status word (code C0150) are
entered here.
Bits 8 to 15 of the status word (code C0150) are
entered here.
•
nvoAifOut1 reads the actual frequency value
Actual frequency value
LOW byte HIGH byte
The actual frequency value is read from code C0050. The actual frequency value with the signed
normalisation 24000 = 480 Hz is provided here.
Network variable to drive
•
nviAIFStw writes the control word ( ^ 6-39)
Control word
LOW byte HIGH byte
Bits 0 to 7 of the control word (code C0135) are
entered here.
Bits 8 to 15 of the control word (code C0135) are
entered here.
•
nviAIFIn1 writes the frequency setpoint
Frequency setpoint
LOW byte HIGH byte
The frequency setpoint (code C0046 via parameter data channel) is selected as process data word.
The normalization differs from the setting under C0046. It is a signed value, 24000 = 480 Hz.
