294 Fieldbus control
Miscellaneous drive control
Note: The user should change only the parameters for the functions you wish to
control vial fieldbus. All other parameters should typically remain at factory default.
For simple start/stop and speed reference fieldbus control, only parameters 1001
EXT1 COMMANDS and 1103 REF1 SELECT need to be changed to COMM.
Using the fieldbus for miscellaneous drive control requires:
• Drive parameter values set as defined below.
• Fieldbus controller supplied reference word(s) in the appropriate location. (The
location is defined by the Protocol Reference, which is protocol dependent.)
1.ABB recommends hard wiring run permissive and safeties.
