Controller Introduction
The EMC series bus controller is an independent bus motion controller developed by Leadshine with independent intellectual property rights. It is designed based on the mainstream EtherCAT expansion bus and supports motion control of up to 64 axes. The main body supports backplane bus expansion, including different types of modules such as IO, AD/DA, and encoders, which is more convenient and efficient than general EtherCAT expansion. The EMC series controllers interact with PCs via network cables, and up to 254 EMC controllers can be networked to achieve distributed control.
Meanwhile, the EMC series also boasts powerful motion control capabilities. In addition to supporting various point-to-point motion planning modes such as T-type, S-type, and S plus, as well as common motion planning functions such as trajectory look-ahead, it also integrates a variety of industry control algorithms such as instruction caching, PSO spacing comparison, and two-dimensional pitch compensation, which are highly compatible with the common process requirements of industries such as 3C, semiconductor, laser, and dispensing.
The EMC series bus controllers are divided into the general-purpose point-to-point 3000 series and the high-end trajectory 5000 series. They are compatible with the original DMC series function interfaces and support multiple systems such as Windows, Linux, and macOS, making them effective and accurate for a wide variety of application scenarios.
Hardware Parameter Description
The basic hardware parameters of the EMC series bus controller are shown in the table below:
Controller Interface Introduction
The EMC series bus controllers come with a rich set of interfaces. The following diagram shows a brief overview of the interfaces of the EMC series bus controllers:
The PC connects to the controller via a network port and sends commands to the controller for processing. The controller expands axes and other types of resources via EtherCAT and a backplane bus. The backplane bus is a custom bus protocol developed by our company and only supports expansion with our main R2 series plug-in modules. The controller supports expansion with I/O, AD/DA, and encoder modules, with a maximum of 32 modules. A physical diagram of the backplane bus expansion is shown below:
The controller itself features 16 inputs and 16 outputs of general-purpose I/O control. The outputs support NPN connection type, while the inputs support both NPN and PNP connection types. The input/output wiring diagram is as follows:
