MC4N-ECAT Mini Master

P900 (2 Axis) | P901 (4 Axis) | P902 (8 Axis) | P903 (16 Axis) | P904 (32 Axis)

The MC4N is a high performance Motion Coordinator which is dedicated to running remote servo and stepper drives via the EtherCAT real time automation bus. It is based on an up-rated version of the 532MHz ARM 11 processor which makes it ideal for high axis count machines or robotic applications.

Plug and Play

The MC4N supports up to 32 axes of motion with 64 bit integer position registers for ultra precise axis resolution. EtherCAT slave drives and I/O can be connected and run in cyclic synchronous position, speed or torque modes provided these are supported by the drive.




The P900 has 2 built-in EtherCAT axes which can be user upgraded with the purchase of P912 Remote Axis FECs.
Each P912 doubles the available axes, i.e:
P900 + 1 x P912 = 4 Remote Axes
P900 + 2 x P912 = 8 Remote Axes
P900 + 3 x P912 = 16 Remote Axes
P900 + 4 x P912 = 32 Remote Axes

Of course, the MC4N can be purchaced with axes factory loaded ie:
P900 = 2 Axes
P901 = 4 Axes
P902 = 8 Axes
P903 = 16 Axes
P904 = 32 Axes

Every axis can be programmed to move using linear, circular or helical or spherical interpolation, electronic cams, linked axes and gearboxes. The power of the controller allows for multiple robotic transformations to run simultaneously.

Easy to use


A bright easy to read backlit display enables the controller status to be easily determined, whilst the single piece metal cast backplate provides an integrated earth chassis to improve noise rejection in the industrial environment.

Familiar Tools


The built-in Ethernet port allows programming and connection of common PLC and HMI protocols, including the Trio Uniplay range of HMIs, directly to the MC4N. User programs can be written in Trio’s established multi-tasking TrioBASIC language using the powerful Motion Perfect v4 application development software making complex motion easy. The industry standard IEC 61131-3 languages are available as an option, allowing a fully functional PLC programming system.

Axis Configuration Key

Core functionality

CORE AXES – can be configured in software as pulse and direction outputs with stepper or servo drives. They can also be configured for incremental encoder feedback.

Core functionality is a set of ATYPEs (Axis TYPEs) that are available on all controllers. They are based on pulse outputs and incremental encoder feedback.

ATYPE Description
43 Pulse and direction output with enable output
45 Quadrature encoder output with enable output
63 Pulse and direction output with Z input
64 Quadrature encoder output with Z input
76 Incremental encoder with Z input
78 Pulse and direction with VFF_GAIN and enable output 1
Extended functionality

EXTENDED AXES – in addition to the Core functionality these axes can also be configured for absolute encoders and closed loop servos (requires voltage output).

Only axes marked as AS have an analogue output and can be used for closed loop control.
All Extended Axes can use these ATYPE's as feedback.
If you want to just use the feedback and not complete a closed loop servo system set SERVO = OFF

Software - Programming
Motion Perfect
Motion Perfect is designed to make setup, diagnostics, commissioning and using our range of Motion Coordinators as simple as possible. It provides the user with an easy to understand Windows based interface for rapid application development, controller configuration and monitoring of controller processes.
IEC 61131-3 Runtime Software (P877)
IEC 61131-3 standardises the programming language, the instruction sets and the handling and structuring of projects. As supplied, the IEC 61131 system will run programs for one hour after power-on, to allow engineers to try out their standard programs on the Motion Coordinator hardware. For continuous running, a software key (Feature Enable Code) can be downloaded from the Trio E-Store or purchased form your distributor for each Motion Coordinator to run IEC 61131 programs.
Software - Expansion
Kinematic Runtime FEC (P750)
The P750 Robot kinematic runtime enables the more complex FRAME transformations which enable easy programming of various types of robot Including SCARA and Delta.
(Log on to E-Store to purchase).

controller + 2 x P912 = 8 Remote Axes
controller + 3 x P912 = 16 Remote Axes
controller + 4 x P912 = 32 Remote Axes

(Log on to E-Store to purchase).
Software - Support Apps
The program allows the user to create motion paths in a CAD package such as AutoCAD and convert them into code executable by a Trio Motion Coordinator.
A compact, self-contained package designed to allow simple distribution of projects written using Motion Perfect. Simply add the project to the Autoloader folder, edit a script file to provide control of the loading sequence and send to the customer.
Trio MCLoader
The Trio MC Loader is a Windows ActiveX control which can load projects (produced with Motion Prefect) and programs onto a Trio Motion Coordinator. Communication with the Motion Cordinator can be via serial link, USB, Ethernet or PCI depending on the Motion Coordinator.
Trio PCMotion
PCMotion is an ActiveX component allowing direct connection to the Trio Motion Coordinator from a custom user application. It can be used to control any of the Motion Coordinator functionality as well as send text files down to the controller.
The file loading functionality of the Motion Coordinators allows files to be easily loaded into the controller memory or the SD card (when fitted). This allows programs written in text based languages such as G-Code and HPGL to be loaded to the controller where they can be parsed and executed by a TrioBASIC program. The transfer process is optimized to compress the file and reduce transfer times, or it can be set to stream the file into a FIFO buffer on the controller. This can help reduce overall machine cycle times when file sizes can be large and so making communication time significant.
