272 PROFINET IO – Start-up
The start sequence for the parameter example above is given
below.
Control word:
• Reset the fieldbus communication fault (if active).
• Enter 47Eh (1150 decimal) –> READY TO SWITCH ON.
• Enter 47Fh (1151 decimal) –> OPERATING (Speed mode).
Position control using the PROFIdrive communication
profile with PPO Type 4
This example shows how to configure a basic positioning
application. The start/stop commands and reference are according
to the PROFIdrive profile, positioning mode. For more information,
see the PROFIdrive state machine on page 313.
Note: By default, fieldbus is not the only control source. See actual
signal 02.12 FBA MAIN CW in ACSM1 Motion Control Program
Firmware Manual for details.
The position set point and velocity reference are defined as 32-bit
integer values; both are scaled as defined in the drive parameter
settings.
The table below gives the recommended drive parameter settings.
