STEP Elevator Control System Mini-Class (Part 2): Interface Introduction
2023-11-07
The elevator control system is the core of an elevator, determining its operational quality and efficiency. With 28 years of deep expertise in the elevator industry, STEP has consistently driven the development of its elevator control system products with “user value” at its heart, striving to perfect every intricate control algorithm, drive mechanism, and user experience with relentless attention to detail.
To help users get started, we’ve launched a series of short tutorials that will introduce the STEP elevator control system in phases, covering various aspects such as debugging, interfaces, and functional testing. We invite everyone to watch, learn, and engage in discussions.
In this issue, let’s take a look at... STEP Core Control Cabinet C7000+ & G9000 For example, let’s get acquainted with the external interfaces of the STEP elevator control system.
Introduction to the Elevator Control Cabinet, Control System Motherboard, and Motherboard Plug-in Board Interfaces
As the core component of the elevator control cabinet system, the elevator control cabinet’s external interfaces primarily include an encoder interface, a power cable interface, a parameter adjustment interface, and an interface for signals from hoistway components. The schematic diagram is shown below:
