We just purchased a Mori Seiki SL3 lathe that's going to be retrofitted with LCNC because it has no control. The machine has a brushed DC spindle motor and from what they told me the DC drive was not working (I would like to check this but I couldn't find any info or manuals for this drive, the model number of the drive is A20B-0008-0372/02). I would like to keep this motor because I like the idea of having high torque at low speeds because I plan to use a milling and hobbing attachment with this lathe.
The A20Bxxx number is for the top board. The part number for the drive is probably near the bottom of the drive and should start with A06Bxxx.
Fanuc drives are good and should be usable but are PRICEY! They wanted $30K plus for new and $13K for rebuilt for a 10KW lathe. I swpped the DC for AC and bought a drive for under $1K.
