That vintage of a VF2 would be good to about 80 ipm contouring before you would notice any jerkiness. Maybe more..
Of course this would depend on how small the line segments where in the program and how sound the machine was. servos, couplers, backlash, etc.
As for the "P"..never heard of a "P" model..a "D" yes..that would be a delta/wye machine without a gear box..but not in 1993...
And in my opinion $8000.00 for a 1993 VF2 in any kind of shape is a good deal..if you get them down to $6000.00 and it is in fair shape you need to go to church and to confession.
