Upgrade ZX Machine to Beckhoff Drives and Control

Auteur avatarStuga Engineer | Dernière modification 16/10/2023 par Stuga Engineer en cours de rédaction

Introduction

The ZX3 and ZX4 machines that have control systems that pre-date the Beckhoff hardware now have an upgrade available. The upgrade will bring up-to-date hardware to the machines control system and drives. The control system and drives will be changed to Beckhoff. TwinCAT 3 PLC and AX8000 series drives.

Étape 1 - Preparation (Base)

Check through all parts lists and make sure that the parts that have been requested are the parts that are in the box. The picked parts should include all the consumable products that are in the BoMs (bolts, tie wraps, wires etc).


Once parts have been checked, they need to be handed to production for pre-assembly.


Ensure all information and drawing packs are available in the service job and in the relevant technical information boards on Monday.com. Link to Monday board for drawing packs here:

Étape 2 - First Fix Servo Cabinet

Before the upgrade is despatched to site, the servo system needs to be assembled and pre-wired in its enclosure.


  • Drill off Fan detail in right hand side of cabinet. A 114mm hole saw and arbor has been purchased for this.
  • Drill and fit 4 adjustable feet in the bottom of the cabinet. 4 extra nuts will be in the kit. The height of the feet does not need to be set at this stage.
  • Drill off all servo drives. For ZX3 machines, the rack will be as follows: AX8640-AX8118-AX8206-AX8206 and for a ZX4 the will be: AX8640-AX8118-AX8206-AX8206-AX8206 (the extra drive is for the V and W axes).
  • Pre-wire the rack (inc STO links) and the cabinet fan with the cable provided in the kit. leave the spare coil of cable in the cabinet ready for running on-site.
  • Plug in the 2x15m green etherCAT cables.
  • The enclosure bottom plate is left off to allow the cable entry on site.

*for detailed wiring information, please use drawing packs from Monday.com board.*



Étape 3 - Preperation (On-Site)

Parts

The parts should arrive on site, packed as a kit. Check the parts for any obvious signs of damage and check through to make sure you have received what was expected.


Expectations

Before starting any works, check in with the customer and make sure that all parties are aware of the scope of the work being undertaken. It is good to set expectations at this point, to keep clarity between you and the customer.


Starting the Job

...Ensure machine is turned off and properly isolated before starting any work!

Check machine condition and get pictures before starting any work. It may be useful to run the machine to check any inherent issues before the upgrade begins. After works have been started, it will not be possible to come back to this stage.




Étape 4 - Remove Components - MH (Electrical)

It is important to note that although the components are being removed from the machine, they are not to be thrown away. Please keep all parts in good condition and find a place to store them until the end of the upgrade process.


Where wiring needs to be disconnected, try and keep crimped ends attached so that the wires can be reused later in the upgrade process.


Parts to be removed from MH cabinet:

  • Main PC.
  • Servo Drives.
  • Breakout boards for Servo drives.
  • Motion controller.
  • Filters and resistors for Servo system.
  • Smartdrive control box and associated cards.
  • All network switches and modem devices.


Étape 5 - Remove Components - Saw (Electrical)

Parts to be removed from Saw Cabinet:

  • Ace PC
  • Nextmove ESB Controller
  • Servo Drive
  • Breakout board for Servo Drive
  • Filter and Resistor for Servo Drive
  • 12Vdc Power Supply

Étape 6 - Remove Components - Saw Infeed (Electrical)

...This is also known as the 'Transfer Cabinet'

Parts to be removed from Saw Infeed Cabinet:

  • B&R PLC (or Omron)
  • LEDs on cabinet door

Étape 7 - Remove Components - Field Components

Parts to be removed:

  • Touchscreen from MH Console
  • Keyboard and PS2 cable from MH Console
  • Touchscreen from Saw Console
  • VGA and any USB or PS2 cables from Saw Consoles
  • Printer serial cable
  • SX axis servo cablesfrom Saw cabinet through to SX axis motor
  • X axis servo cables from MH rear plug join to X axis motor
  • X axis servo cables from MH drop down panel to MH rear plug join
  • G axis stepper cable from MH drop down panel to MH rear plug join
  • Y, Z and R axis servo cables from MH drop down panel to servo motors
  • X, Y, Z and R axis servo cables from MH Cabinet to MH drop down panel
  • G axis stepper cable from MH cabinet to MH drop down panel

Étape 8 - Fit Parts - MH (Electrical)

...When fitting IO slices, try and place them in such a way that existing IO wiring will reach the terminals.

Parts to be fitted in MH cabinet:

  • Beckhoff IO Slices
  • Beckhoff IPC
  • Front End PC
  • 24Vdc 10A Power Supply
  • 3Pole 10A Breaker for Servo System
  • 1Pole 3A Breaker for 24Vdc 10A Power Supply
  • Din Mount Network Switch

*For any IO wiring that will not reach the IO slices, terminals are provided in the kit. The terminals can be used to extend the wiring.*

Étape 9 - Fit Parts - Saw (Electrical)

...When fitting IO slices, try and place them in such a way that existing IO wiring will reach the terminals.

Parts to be fitted in Saw Cabinet:

  • Beckhoff IO Slices
  • Din Mount Network Switch


Étape 10 - Fit Parts - Transfer (Electrical)

...When fitting IO slices, try and place them in such a way that existing IO wiring will reach the terminals.

Parts to be fitted in Saw Infeed Cabinet:

  • Beckhoff IO Slices

Étape 11 - Fit Servo Cabinet

Position:

The servo cabinet will arrive pre-wired and have 4 feet fitted to the bottom. The cabinet needs to be placed at the rear of the MH outfeed, just after the first eject push cylinder. To get the cabinet inplace, the first fence panel will need to be removed. Eventually this fence panel will need to be cut to allow the cabinet door to open.

Fixing:

To fit the cabinet, first set the feet so that the top rear holes of the cabinet line up with the round bar frame of the MH outfeed. Once the holes line up, they can be drilled off and fixed.

Cables:

The cabinet will have a power cable and 2 network cables that need to be loomed out of the bottom panel of the cabinet. The power cable and network cable labelled MH, run into the MH, through the internal trunking, through the drop down panel (ensure cables are run and secured in such a fashion that the drop down panel can be open or closed without causing any clashes or breaks for the cables. The cables then run down the infeed table trunking and into the MH electrical cabinet.

The network cable labelled Saw, will eventually run through the front buffer beam of the transfer table, but at this stage it just need to be loomed up to the entrance of the buffer beam, ready for pulling through with some other cables later on.

Étape 12 - Wiring Cabinets

Now all wiring and devices have been fitted in the cabinets. Use the schematics provided to wire them up.


The schematics can be found on the Monday.com board linked at the start of this Dokit.

Étape 13 - Run Machine Cabling

Cables that need to be run:

HDMI Cable

The HDMI Cable runs from the Front end PC in the MH Cabinet to the Saw Console touchscreen. The cable comes out of the MH cabinet, down the infeed trunking, through the drop down panel (again ensuring the drop down panel can function normally without impacting on the cable) and then through the internal trunking in the MH, eventually coming out of the outfeed side of the MH (using the hole created from removing the G axis connection plug). The HDMI cable and network cable labelled Saw can now be pulled through the front buffer beam of the machine using an old piece of cable if required. Once the cables are out of the other side, they need to be loomed into the Saw cabinet.

...On Z010, the Saw cabinet was underneath the Saw Outfeed which made it possible to loom the cables round the rear of the Saw hood and then drop down into the Saw Cabinet via a gland. Other upgrades may be different!
