Appreciating “Hard” Power ┃ Section 1: Hardware Architecture and Functions of the SC20 Motion Controller
2022-09-06
Hello everyone, the SC series is a PCA product launched by STEPeng in 2021, featuring... Integrated control, one-stop connectivity, and a single-platform design. Its features are highly favored by users. To help everyone better understand and make more effective use of the SC series, we’re launching the SC Tutorial Series starting today. This course will take a gradual approach, from basic to advanced levels, and will be divided into... Hardware, software, and functional applications We’ll introduce each of the major chapters one by one. Today, let’s start with the hardware section and get to know SC20 together.
Two versions of the SC20 series motion controller
The SC20 controller features a rich interface structure and outstanding overall performance, making it capable of meeting the needs of various applications. It supports... Interpolation, electronic cam, electronic gearing, position latching, synchronous following, virtual axis configuration, EtherCAT bus control and other functions; the optimized NET network port can serve both as an Ethernet communication interface and as an EtherCAT bus communication interface.
#1 Programming Language
In addition to fully complying with the international PLC programming standard IEC61131-3, it also conforms to the PLCOpen motion control specifications. Eliminate technical differences and barriers among program developers, thereby maximizing the interoperability of users’ programming skills.
The STEP AS programming software, developed based on the CODESYS platform, supports six programming languages: Ladder Diagram LD, Structured Text ST, Instruction List IL, Sequential Function Chart SFC, Function Block Diagram FBD, and Continuous Function Chart CFC.
#2 Hardware Interface
High interface integration, diversified communication methods, integrated pulse control, and bus-based control—these are its key features.
It integrates multiple industrial interfaces, including RS485, RS232, CAN, USB, and other industrial interfaces, meeting communication needs in a wide variety of scenarios.
It integrates EtherCAT bus-axis and pulse-axis interfaces, meeting the control requirements of both bus-type servo drives and pulse-type servo drives. Via EtherCAT bus communication, up to 16 motion axes can be connected.
It supports both integrated plug-in expansion and EtherCAT remote bus-based expansion, and is compatible with digital input/output IO and analog input/output IO. Through the plug-in expansion units, the system can support up to 512 IO points.
