Example for writing a parameter via MOVILINK
®
The following tables show the structure of the WRITE and READ services for volatile
writing of the value 100 to parameter
P170 fixed setpoint n0
of the connected
MOVIMOT
®
MM..D drive. The MOVILINK
®
service "WRITE parameter volatile" is used
for this purpose.

Downward-compatible routing via DS47
If DIP switch S1/1 = "OFF", the system
transfers the DS47 request with the
axis address 2 to the RS485 address
254 of the MOVIMOT
®
.

via DS47
If DIP switch S1/1 = "ON", the system
transfers the DS47 request with the
