Overview
The major part of the functionality of SINAMICS drives is imple-
mented in software. This "embedded"
software
delivers the
function of the product and is therefore a significant component
of the overall product. The embedded software is also known as
firmware
, because it is firmly connected to specific hardware.
In the case of SINAMICS drives, the firmware is subdivided into
the
operating system (OS)
with drivers for the hardware and the
inverter functions, which are also referred to as the
runtime (RT)
functions
.
Introduction
The available firmware functions are so extensive that the overall
functional scope has been structured into function groups
corresponding to their main applications.
The 8 main groups are:
•
Basic Drive Functions
•
Standard Technology Functions
•
Advanced Technology Functions
•
Communication Functions
•
Safety Integrated Functions
•
Energy Efficiency Functions
•
Common Engineering
•
Applications & Branch know-how
Functionality, including technology and configuration
Basic Drive Functions
The main groups, especially the "Basic Drive Functions", are
divided up into further subgroups.
• Control
• Availability
•
Setpoints and commands
•
Limiters, timers and monitoring functions
• Diagnostics
• Protection
Basic Drive Functions – Control Function
Control
The control methods are the core of the entire inverter firmware.
They are responsible for optimum movement of the connected
motor and the attached machines. The better the control
functions, the faster, better and more smoothly the machine
operates, thereby significantly enhancing the quality of the
production output.
A distinction is made between the following methods:
•
V/f control (open-loop control)
•
Vector control (closed-loop control)
•
Servo control (closed-loop control)
Further classification refers to the control variables:
•
Current control
•
Speed control
•
Torque control
•
Position control
•
Technological process control (pressure, flow rate,
temperature, fill level, etc.)
