9.3 Motor data
Communication information for the different motors.
M1 contains parameters 43041 to 43048. The M2, M3, and
M4 contains the same type of information. For example
parameter 43043 in motor M1 contain the same type of
information as 44043 in M2.
9.4 Start and stop commands
Set start and stop commands via serial communication.
9.5 Reference signal
When menu “Reference Control [214]” is set to “Com” the
following parameter data should be used:
9.5.1 Process value
It is also possible to send the Process value feedback
signal over a bus (e.g. from a process or temperature sensor)
for use with PID Process controller [380].
Set menu “Process Source [321]” to F(Bus). Use following
parameter data for the process value:
Example:
(See Emotron Fielbus manual for detailed information)
We would like to control the AC drive over a bus system
using the first two bytes of the Basic Control Message by
setting menu “[2661] FB Signal 1” to 49972. Further, we
also want to transmit a 16 bit signed reference and a 16 bit
process value. This is done by setting menu
“[2662] FB Signal 2” to 42905 and menu “[2663] FB Signal
3” to 42906.
