Overview
Scope of functions scaled by technology packages
The SIMOTION technology packages expand the basic
functionality of the SIMOTION devices with additional language
commands which makes adaptation to the respective
automation task easy.
The loadable technology packages support the creation of
technology objects (e.g. positioning and synchronous axis, cam
paths, external encoders) which can be accessed over system
functions and system variables for use in every SIMOTION
programming language.

Function
SIMOTION Motion Control technology package
The Motion Control Basic technology functions can be used
without a license. Use of the extended functions of the Motion
Control technology package is subject to a license.
The comprehensive functions of the Motion Control technology
package offer very open and flexible ways of influencing
application programming and ensure that you can also
implement future Motion Control applications.
Using the Motion Control functions in conjunction with the
powerful PLC functionality results in high machine cycles thanks
to short response times as well as high product quality thanks to
reproducible machine behavior.
Technology functions for Motion Control Basic
The speed-controlled axis technology object
•
Speed setpoints are defined in the program (for servo and
vector drives)
•
In addition, accumulative torque setpoints and torque limits
can be defined, for example, for controlling a winder drive with
tension control
•
Access to status and control words of the drive
Release sequence of the PROFIdrive units can be specifically
controlled (e.g. for braking control signal)
•
Reading and writing of drive parameters
•
Support for SINAMICS drives which can perform safety-
related motion monitoring functions such as Safe Operating
Stop (SOS), Safely Limited Speed (SLS), Safe Speed Monitor
(SSM) and Safe Direction (SDI), safety-related position
monitoring such as Safely Limited Position (SLP) and safe
position transmission (SP) or safe stop reactions such as Safe
Torque Off (STO), Safe Stop 1 (SS1), Safe Stop 2 (SS2).
The purpose of this support is to prevent stop reactions by the
drive, where SIMOTION uses the application to regulate the
drive, e.g. within permissible velocity limits (with SLS) or stop
the drive (e.g. with SOS).
Activation and deactivation of SINAMICS Safety Integrated
Extended Functions STO, SS1, SS2, SOS, SLS, SDI, SLP as
well as their status are indicated on the axis by specific
technology alarms and system variables.
Further information about SINAMICS Safety Integrated can be
found in section Safety Integrated.
External encoder technology object
External encoders can be used to detect actual position values
of axes (on PROFINET/PROFIBUS, onboard for C240 and as a
2nd encoder on the drive).
Cam and cam track technology object
•
Generates position-dependent switching signals
•
Number of cams and cam tracks depend on available system
resources
•
Each cam track can have up to 32 cams on one output
The following cam types are available:
•
Trip cams
•
Position-position cams
•
Position-time cams
•
Position-time-based cams with maximum ON length
•
Counter cams
•
Exact time setting of an output, exact time output cams
The cam statuses can be output with:
•
Internal variables
•
Standard digital outputs
(SIMATIC ET 200SP, SIMATIC ET 200MP, ...)
•
Onboard outputs of SIMOTION C, D and cam outputs on
TM15, ET 200SP and ET 200MP TM Timer DIDQ
(for high accuracy requirements in the μs range)
•
The output can be inverted
