I just started a retrofit on an EMCOTURN 140 lathe.
I sold the original control in favor of running this lathe from Mach3
I am going with a VFD/3 phase motor for the spindle,850 oz/in servos with encoders for x & z axis.
I have pretty much everything purchased from CNC4PC.
I have the enclosure constructed and mounted on the machine.
The spindle motor adapter plate and pulley adapter are made and the motor is mounted on the lathe and a quick test has been run just to check out the VFD and motor combo,
I have the demo version of Mach installed on the pc with a touch screen monitor.
I am just starting to mount the power supply,VFD,computer motherboard and c32 board plus 320x geckos and wanted to check on opinions
of having this all in the same inclosure.
I have enough room to neatly mount everything but want to know if I should be concerned of interference from the power supply or VFD to the servo power lines or with the encoders.
Here is a list of parts I have to work with
Hitachi X200 VFD
72v-20 amp power supply
850 oz.in servos with encoders
C32 CNC4PC board
Spindle index pulse board
Also am adding a second PCI parallel port in the pc to handle a rotary MPG and axis selection/resolution board
I would appreciate any input before I get into any trouble
I have done a cnc conversion on a 3-1 lathe/mill but with steppers
and built a cnc router also with geckos and steppers but these were simple compared to what I am doing now so
I am uncertain as to what to look out for
Thanks in advance
(If there is a better place to post this I hope that a moderator will feel free to move it)
