4.1 Introduction
The protocol for RS 232 connection to motor controller is ASCII-based.
Motor controller will normally only transmit to FBG10 in response to a command/request
sent from FBG10. In connection with error conditions in motor controller, this can howe-
ver send error messages unprovoked. These unprovoked messages is not supported by
FBG10, but will result in a conversion error. See section
3.7.1, "Status description" , page
24.
Certain commands to a controller, will result in a longer statements from the motor con-
troller. For example can the command: "Show servo constants", ( K ), result in the respon-
se:
KD=70
KI=10
KP=40
KVFF=10
IL=100
BIAS=0
As FBG10 can not convert this to a PROFIBUS response, such commands are not sup-
ported. Supported commands can be seen from the conversion table in section
5, "Con-
version Table" , page 35
