The CPU provides motion control functionality for the operation of stepper motors and servo
motors with pulse interface. The motion control functionality takes over the control and
monitoring of the drives.
● The "Axis" technology object configures the mechanical drive data, drive interface,
dynamic parameters, and other drive properties.
● You configure the pulse and direction outputs of the CPU for controlling the drive.
● Your user program uses the motion control instructions to control the axis and to initiate
motion tasks.
● Use the PROFINET interface to establish the online connection between the CPU and the
programming device. In addition to the online functions of the CPU, additional
commissioning and diagnostic functions are available for motion control.
Note
Changes that you make to the motion control configuration and download in RUN mode
do not take effect until the CPU transitions from STOP to RUN m
ode.
