The Fundamentals Of Motion Control - Siemens SIMOTION Operating Instructions Manual

Description

2.3 The fundamentals of motion control

These modules are integrated via the GSD file from the device manufacturer.
Note
Please note that in individual cases further boundary conditions must be fulfilled in order to
integrate a standard slave into SIMOTION. Some modules need "driver blocks", e.g. in the
form of function blocks, which make integration possible or much easier.
For modules approved for use with SIMOTION (e.g. S7-300 module FM 350-1, etc.), these
driver blocks:
● Up to V3.2 SP1: SIMOTION Function Library
● As of V4.0: SCOUT command library
2.3 The fundamentals of motion control
Position-controlled motion control for servo axes via the onboard drive interface (C230-2, C240)
These enable position-controlled motion control of up to four axes. The C230-2/C240 provides
one analog output per axis for the speed setpoint and one encoder input per axis for the cyclic
measurement of the actual position value.

Incremental encoder (C230-2, C240)
For position measurement, the encoders usually connected supply counting pulses according
to their resolution for the distances traveled. These can be rotary encoders or linear scales.
Homing is necessary to determine the absolute position reference.
