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.
