All machine functions are initiated by the DEK software installed on the PC The

PC transmits and receives information to the NextMove ES card in the M36 Machine Control Enclosure using a single USB lead The NextMove ES card incorporates its own processor which handles machine motions and switch/ sensor feedback, this frees up the PC processor to run the MMI and other peripherals.

The NextMove ES card incorporates a USB encoder/decoder and a CAN encoder/decoder interfacing between the PC and the following:

• NextMove Interface Card

• Stepper Drive Cards

• EF Servo Drive Cards

• I/O Node Boards (via CAN Bus)

• Servo/Stepper Nodes (via CAN Bus)

M36 MACHINE CONTROL ENCLOSURE

The M36 Machine Control Enclosure is located at the rear of the machine and interfaces between the PC and machine motors, sensors and switches The

PC connects to the M36 with a USB cable allowing two-way communications between the two enclosures.

The M36 enclosure has a single backplane PCB with edge connectors mounted

on one side for plug-in cards (Slot X1 to X7) and plugs and sockets on the other side, protruding through the rear panel, for connection to the machine looms The front panel has a cut-out slot to allow connection of the USB and CAN Bus cables to the NextMove ES card in Slot X5.

The NextMove ES can control six stepper motor axes via stepper drive cards and provides 4 analogue outputs, 2 analogue inputs, 20 digital inputs (interfaced through the NextMove Interface card) and 8 digital outputs (interfaced through the NextMove Interface card) Two of the analogue outputs are used as demand outputs to control linear motors for camera X and Camera Y (linear drive machines only) The card also incorporates a CAN encoder/decoder which connects to I/O Node boards and Servo/Stepper Nodes using a CAN Bus network The CAN Bus network allows for future expansion of the system without the need for further NextMove cards.

There are four surface mount LEDs on the board which are detailed in the table below, NextMove ES Card figure refers:

Dual Stepper Drive Card

CAUTION ANTI-STATIC HANDLING STANDARD PRECAUTIONS MUST BE ADHERED TO WHEN HANDLING ELECTRONIC CARDS AND CONFIGURING AND INSERTING INTO THE ENCLOSURES.

The dual stepper drive card consists of two identical stepper motor drive circuits used to drive two stepper motors, in half-step mode.

Each of the twin channels of this card consists of an IC (A3977SED) which combines the conversion of the Step and Direction inputs into control signals for the output to the stepper motor These control signals sequence the current in each of a pair of DMOS (Diffused Metal Oxide Semiconductor) H-bridge motor drivers.

The card is connected to both the +24V SW and +24V US supplies The switched (SW) supply is protected by a diode-fuse transient suppressor circuit The diode operates over an extremely short time period, enabling the circuit to absorb voltage spikes without rupturing the fuse (F1 - 4Amp) If a sustained voltage is experienced above its rating, the fuse ruptures The +24V US is used

to produce an internally regulated +5.5V (VCC and VDD).

Whilst the stepper motor is stationary, the card switches to half power to minimize power consumption.

The card utilizes the mixed decay feature of the IC to achieve the best sinusoidal motor current waveform for stepper motors This decreases current ripple and hence decreases motor heating.

Each channel has a separate dipswitch which enables various circuit functions and are shown in the table below:

1 Enables Full/Half/Quarter/Eighth Step Operation

CAN BUS

The Controller Area Network (CAN) is a bus system for machine motion control

An encoder/decoder for the 500Kbit/s rate CAN serial link is fitted to the NextMove ES card to enable communication with the CAN Nodes The CAN is

a 2-wire data link designed for transmission of small data packets for fast update

of axis position information.

The CAN Bus connects the NextMove ES card to the Nodes that provide machine motion, switch functions and sensor feedback There are two different types of Nodes:

• I/O Node Boards

• Servo/Stepper Nodes For the CAN Bus to work correctly, the CAN Bus must be terminated using a CAN Terminator The CAN Terminator is fitted to the output connector of the last node in the CAN Bus line and consists of a 9 pin D type connector with a link resistor fitted inside the connector hood.

I/O Node Boards

CAUTION ANTI-STATIC HANDLING STANDARD PRECAUTIONS MUST BE ADHERED TO WHEN HANDLING ELECTRONIC CARDS AND CONFIGURING AND INSERTING INTO THE ENCLOSURES.

The I/O Node Boards consists of multiple inputs and outputs, CAN encoder/ decoder and multi-way connectors for machine components.

There are three I/O Node Boards fitted to a standard machine with a possible one other board for the underscreen cleaner, if fitted, these are:

• I/O Node 1 - NextMove ES card (CAN master) located in the M36 Machine Control Enclosure (standard)

• I/O Node 2 - Main Machine I/O board located at the rear of the machine (standard)

• I/O Node 3 - Print Carriage I/O board located inside the print carriage extrusion (standard)

• I/O Node 4 - Screen Cleaner I/O board located at the rear of the machine (optional)

I/O Nodes 2 & 4 have a green (status) and a red (error) LED mounted on the board The status LED should flash twice periodically and the error LED should not be illuminated during normal operation The following table describes other operations of the LEDs:

I/O Node 1 I/O Node 1 is the CAN master and is also known as the NextMove ES card

housed in the M36 Machine Control Enclosure For more information, refer to the M36 Machine Control Enclosure - NextMove ES Card section of this chapter.
