i think you are out of luck, you need a servo system to do that not a vfd

i had a 436 servo drive alarm on my control last year,when i powered it up after a few years of idle time. turned out to be a bad cpu10 card. There was no light output from fiber #4 transmitter. you could pull off fiber #4 and look for a red light from the led.

a solid state relay should work without being noisy ?

i believe with oak the scales are only a second measuring system, you will still need an encoder signal to oak as the primary feedback, can you tap an encoder signal out of the indramat drives?

you most likely have siemens or indramat drives and servos. most of the siemens stuff of that era used hall effect feedback to the drive, so you will have to add an incremental encoder to each servo for the oak board in addition to the scales

if anyone is interested, i have found BEI makes exactly what is needed, its called SWIFTCOMM wireless encoder interface.

there is nothing wrong with his zero max servo couplings, i have used them with excellent results with high end siemens motors and controls with no problems

why do you think the drives would be too old?

the old drives are probably +/- 10 volt analog velocity drives, an oak is supposed to operate velocity or position drives, you would just have to add encoders for the cnc

Hello I am interested in the feasibility of mounting a scale on a boring mill facing head and using a battery pack to power it and some type of transmitter to provide wireless feedback to a receiver that would be connected to an oak board encoder port. Has anyone attempted this and if it worked can ...
