Hi all,
I have a crazy opportunity to get myself an 4000x2000mm ATC router.
It does have some issues but at a price per kg it's more than a bargain!
The specs are:
Dimensions: 4500x2500mm (working area 4200x2000x200mm)
Spindle: HSD ES 330A 4.5kW Air cooled ATC ISO30
VFD: Omron (Yaskawa V1000 3phase)
Servo drive: Omron (Yaskawa SGDH 08AE-S-OY + NS100)
Servo motor: Yaskawa SGMAH-08AAA61D-0Y, 750W, 200V, 3000rpm
Servo gearbox: Wittenstein alpha LP 070-M01-10, 1:10
Control unit: Osai 10/510
Rack and pinion: helical approx 20mm wide, not sure about exact dimensions
Linear rails: PMI-AMT 25 table, PMI-AMT 20 gantry, not sure but i presume 15 or 20 on the Z axis
Tools: Linear ATC 12 positions ISO30
Vacuum: 2X Becker 5.5kW pumps, 4 vacuum zones (electronic actuation of individual zones)
Air/Mist coolant: electronic actuation
Automatic tool measuring mounted on table frame
All accessories are 24V
Construction is very robust, i don't have exact numbers but I would say table is made of 150x180mm steel RHS, table braces 100x100mm steel RHS, gantry is around 280x250mm steel RHS. Not sure about wall thickness, but it's quite thick.
The main issue is control unit. It's Osai 10/510 and its on it's last legs.
I Have 99% decided on UC300ETH-5LPT + UCBB breakout board + 2xIDC26-IDC26 cables + free UCCNC license key. For 212€ that is hard to beat. Other options were Acorn and Masso but they are at least 3X in price.
I do have concerns about number of relays that I'll need
Is there an option to run servos with modbus? and what would be the advantage vs pulse/dir?
Essentially I need to replace the control unit and rewire everything, I'm not sure if that is possible and to what extent.
The bonus is that machine schematics are lost (I'm trying to obtain a copy as that would make things much easier)
Any experience? advice? comments?
