Configuring The Motion Profiles - Siemens SIMATIC S7 System Manual

Specify the following times in milliseconds:
● ACCEL_TIME: Time required for the motor to accelerate from SS_SPEED to
MAX_SPEED. Default = 1000 ms
● DECEL_TIME: Time required for the motor to decelerate from MAX_SPEED to
SS_SPEED. Default = 1000 ms

Configuring the motion profiles

A profile is a pre-defined motion description consisting of one or more speeds of movement
that effect a change in position from a starting point to an ending point. You do not have to
define a profile in order to use the Axis of Motion. The Motion wizard provides instructions for
you to use to control moves without running a profile.
A profile is programmed in steps consisting of an acceleration/deceleration to a target speed
followed by a fixed number of pulses at the target speed. In the case of single step moves or
the last step in a move, there is also a deceleration from the target speed (last target speed)
to stop.
The Axis of Motion supports a maximum of 32 profiles.
Defining the motion profile
The Motion wizard guides you through a motion profile definition, where you define each
motion profile for your application. For each profile, you select the operating mode and
define the specifics of each individual step for the profile. The Motion wizard also allows you
to define a symbolic name for each profile by simply entering the symbol name as you define
the profile.
