After planning for months and adapting the motors to the machine I
finally ordered my drive cards. I ordered a set from Rutex (sorry
Mariss) since I needed something that would drive the 1/2HP PWM DC
Servo motors running at 130VDC. Rutex had a new version that is
rated at 200V @ 40A.
The machine is a large Gorton mill (equal to a Bridgport II). I
replaced the standard acme screws with zero backlash 1.125" dia
ballscrews and nuts. I was lucky and salvaged the screws and nuts
off a piece of surplus. I mounted the motors to custom made brackets
and used 4:1 toothed belt pully sets.
I installed a Shooting Star DRO last year and the sender unit has
standard 5V rotary encoders so I am going to use actual table
position for feedback by "stealing" the signal from each sender unit.
I haven't gotten the driver cards in yet but when I do and start the
final hook ups, I will keep the list updated.
