my haas mini to hickory controller spindle motor question

[jcoldon]

hickory ethercat haas mini mill 2001 .
spindle motor curently use ac 320 volt using a haas servo amplifier

i know i have to replace the haas drive this something motor 800 rpm looks like 3 phase motor 10 hp there no tags

question what would be my best choice make model on VFD to control the spindle motor it need encoder input for spindle orientation
how does hickory handle that

the other how does hickory handle tool changer wiring
haas using dc motors with limit switches it turns and triggers 1 switch it not servo driven
in and out the same 2 limit switches

Currently HICKORY only supports analog 0V to 10V / -10V to 10V output to VFDs. You can use one of the three encoder input ports on the HICKORY to read spindle speed into CNC12. If you want to use things like rigid tapping then I would look into a VFD that has encoder output.

Spindle orient is commanded from a PLC output on the HICKORY so the VFD should have an input for that command.

Your toolchanger would be controlled via the PLC and the tool change macro. I think we have some examples for other boards that should help figure it out.

[jcoldon]

was looking at a automation direct they say it full plc drive for the io .
GS4-2025
DURApulse GS4 series AC high-performance drive, NEMA 1, 230 VAC, 25hp with 3-phase input, 10hp with 1-phase input, SVC or V/Hz mode, C frame, RS-485, Modbus and BACnet, 100kA SCCR. Optional EtherNet/IP and Modbus TCP cards available.

does centroid have a brand they recommend delta c2000 was mentioned

[spikee]

Durapulse = rebranded delta ; C2000 can drive almost all AC induction / Permanent magnet AC spindle motors.
Including encoder feedback, spindle orientation etc.
I found this a quite interesting video:


For my retrofit I'm planning to do the same.
Within china, they are quite affordable. 4kw model is about 350 euro.

[jcoldon]

that the drive everyone telling me work delts C2000

But were does one buy a delta from direct from delta

Does your machine have changeable gears (i.e. high range / low range) between the spindle motor and the spindle?

If your machine does have changeable gears between the spindle motor and the spindle, then is the spindle encoder connected to the motor, or is the spindle encoder connected to the machine spindle?

And a similar question:
Even if your machine does not have changeable gears, does it have an unequal belt or gear ratio between the spindle motor and the spindle? I.e., does one turn of the motor result in exactly one turn of the spindle?

[jcoldon]

theirs no change gears this haas mill . the encoder connects to the motor shaft

[cncsnw]

Then, as long as the motor either drives the spindle directly, or drives the spindle at a 1:1 ratio using a toothed timing belt, then you can do spindle orientation using the motor encoder, with a drive like the Delta C2000.

That requires, of course, that the spindle motor encoder is truly a quadrature encoder with differential output. That type of encoder would have an 8-conductor cable (8 wires, or 4 pairs of wires, in one cable).

[jcoldon]

i understand the part of the encoder and what it can do . The spindle on haas mini is timing belt driven . the encoder timing belt ton the top of the spindle motor so that all good .

the hickory uses encoder to oriant the spindle i get that part

what i don't get is if doing rigid tapping there need in puts to the vfd not sur what that for

i did find a vfd that automation direct sells that they say supports milling and ridged tap even has a mill setting in the drive.
i saw a user video on that part but no explanation on rigid tap part. other then he using it

baggiest Queston of all will vector vfd drive run the haas motor i think i have to buy the drive and try i see no other way

For spindle orient, the VFD needs an encoder coupled 1:1 to the MOTOR shaft. For rigid tapping, Centroid needs an encoder coupled 1:1 to the SPINDLE.

If the motor and spindle are connected with a toothed belt that cannot slip at a 1:1 ratio, then only a single encoder is needed and that is usually attached to the VFD. On most VFDs with an encoder input, they also have an encoder pass-thru that can be connected to the Centroid controller.

If no encoder pass-thru or the motor and spindle are connected at a ratio that is not 1:1, then two encoders are needed.
