Re: Mori Seiki BB spindle motor with Centroid

Bardac makes a pretty good DC motor controller several centroid retrofitters have used them in the case where a machine has a DC motor and is too cost prohibitive to refit with an AC motor.

Re: Bench Check

the allin1dc can accept 20 to 180 VDC "bus voltage" that is used to run the servo motors. its up to you to step down the AC input voltage to the CAPboard so that when that AC is rectified the proper DC voltage is created to match the specification of the servo motors you are using. for exa...

Re: Added a DC1 to an existing working 3 axis control....

also be sure to adjust the Fast, Slow and Rapid rates for the rotary axis.. as they will now be in degrees per minute.. so typical values are
Slow jog = 2000 degrees per minute
Fast Jog 4000 Rapid 9000

i attached a rotary table install manual as a general guide

Re: Added a DC1 to an existing working 3 axis control....

when you define an axis in the CNC11 setup parameters as a rotary axis (not linear) the turns ratio units in the setup table want REV/Degree revolution of the servo motor per degree of movement so in other words.. how many revs of the servo motor will produce 1 degree of movement on the rotary table.

Re: Moving Y- Limit to increse travel. What tasks follow in

yes, move the switch, check action with estop depressed to make sure the swtich triggers before you run out of travel. its good to leave .050" or so. then reset travel limits.
take a look at this tb
