appendix c – process data contents
Process Data OUT (Slave
Master)
The fieldbus master can read the frequency converter’s actual values using process data variables.
Basic, Standard, Local/Remote, Multi-Step, PID control and Pump and fan control
applications use
process data as follows:
Data

Unit
Scale
Process data OUT 1
Output Frequency
Hz
0,01 Hz
Process data OUT 2
Motor Speed
rpm
1 rpm
Process data OUT 3
Motor Current

0,1 V
The
Multipurpose
application has a selector parameter for every Process Data. The monitoring values
and drive parameters can be selected using the ID number (see NX All in One Application Manual,
Tables for monitoring values and parameters). Default selections are as in the table above.
Process Data IN (Master -> Slave)
ControlWord, Reference and Process Data are used with All-in One applications as follows:
Basic, Standard, Local/Remote, Multi-Step applications
