Appendix B—Process Data Values
Process data OUT (slave master)
The fieldbus master can read the frequency converter’s actual values using process data variables. All software applications
use process data as follows:
Table 207. Process data OUT (slave
master)
Data Value Unit Scale Default, Min., Max.
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 A 0.1 A
Process data out 4 Motor torque % 0.10%
Process data out 5 Motor power % 0.10%
Process data out 6 Motor voltage V 0.1 V
Process data out 7 DC link voltage V 1 V
Process data out 8 Latest fault code
ote: N The communication parameter group in any application has a selector parameter for every process data.
The monitoring values and drive parameters can be selected using the ID number. Default selections are shown in the
table above. Reference Appendix A for Modbus IDs that can be set via the keypad FB Process Data Out group.
Process data IN (master slave)
Control word, Reference and Process Data are used with All-in-One applications as follows:
Table 208. Process data IN (master
slave) for all applications
Data Value Unit Scale Default
Process Data in 1 FB Torque Reference % 0.01 0
Process Data in 2 FB Setpoint 1 varies varies 0
Process Data in 3 FB Feedback 1 varies varies 0
Process Data in 4 Accel Time 1 s 0.1 varies
Process Data in 5 Decel Tiime 1 s 0.1 varies
Process Data in 6 Current Limit A 0.1 varies
Process Data in 7 Not Assigned — — —
Process Data in 8 Not Assigned — — —
ote: N The communication parameter group in any application has a selector parameter for every process data. The
monitoring values and drive parameters can be selected using the ID number. Default selections are shown in the
table above. Reference Appendix A for Modbus IDs that can be set via the keypad B Process Data IN group.
