Deckel DMU 60T Index problem
« on: March 10, 2018, 05:20:12 PM »
Hello,
I retrofit in Deckel DMU 60T with a CSMIO IP-A and MACH 4 industry. Now I have a problem.
The machine has some linear scale with only one index signal at 10mm befor end of the traversing distance.
Original the machine was using this signal for homing. Then i tryed to use thissignal  over a signelconverter rs422 to HTL, but the signal is to fast.the csmio is not recognize this signal.
Now i am thinking to use the index hardware counter from the CSMIO. Is ther a changse to read the counter from mach4? So i can programm an function. I canĀ“t find any function/command discrition in the internet.

Anybody an  ideas or some other suggestion?

Thx

If the liniar encoder is differential quadrature, you should be able to feed it directly to the CSMIO/IP-A encoder input. Motor encoder signals would continue to be fed directly to the servo drives, but would not be relayed to the CSMIO.

With this type of setup, you would implement the velocity loop within the servo drive, and the position loop within the CSMIO/IP-A.

I would add that I have no experience of doing this.
