How transferable are the PID settings? Only somewhat, and then only if you read them right. The values displayed by CNC7CONV include a scaling factor of 256, so what you had was Kp = 1, Ki = 0.004, Kd = 20. With the Allin1DC you might start with Kp = 1, Ki = 0.004, Kd = 3 If you get an unacceptable...

There is no voltage on Oak pins 25 + 26. The SUM on PID screen ramps up to 2560000 and stops then I press jog and Oak faults out. Drive wont reenable until i cycle power to Oak. There is no need to cycle power. Just press and then release your emergency stop button to clear the stall/fault conditio...

You could try some experiments with M120 and M223, to write text to a serial port that you have configured. If that works, then you could write your own M3, M4 and M5 macros to send appropriate commands to the spindle drive. You will, of course, have to devise some separate way to ensure that the sp...

An unfortunate historical artifact. Mill software came first, and it made sense to specify the parameter number directly with the P value. Then when lathe software was developed, it was intended to be consistent with Fanuc 0T and similar controls. On a Fanuc 0T lathe control, "G10 P1 ..." ...

Got 3.267 vdc on pins 9 and 10 ... Should i be using Oak pins 25 and 26 for analog signal? I did not see any voltage on these pins. Didn't you say you had Oak pins 25 and 26 wired to drive pins 9 and 10? If you have 3.267V on drive pins 9 and 10, where is it coming from, if not from the Oak? You ca...

According to the report_*.txt file, that is v5.08, not v5.10.

It appears that your plcmsg.txt file is missing altogether.

It depends on the CNC7 version; whether you can start up and run the DOS computer; and whether you can run CNC7. If you can start it up and run CNC7, then you can probably make a Report onto a floppy disk. In later CNC7 version (8.xx), the Report will include a file named CNC7CFG.TXT which has all t...

There are lots of ways to use timers to make something happen repeatedly/periodically. The simplest form, which I use for blinking lights and similar applications, requires just one timer. Alternating_T IS T__ AlternatingBit_M IS MEM__ ;... IF True THEN Alternating_T = 500, SET Alternating_T IF Alte...

Your RTK2 status LEDs indicate a problem with OUT16 getting to the PLC, which is normally a sign of a problem with fiber #1 (TXS). See http://www.cncsnw.com/RTK2StatusLEDs.htm However, I am not convinced that your PLC program is managing OUT16 and INP16 appropriately. You might try installing the at...

I'm not well versed in centroid. But does not have some kind of compensation so you can just calibrate whatever offset or error out? Not built in, but you could make your own if you really wanted to. That would work only if the response is repeatable and linear. Search your PLC program source for &...
