AcornSIX was intended to run without motor encoders feeding back to it.
ENCEXP12 encoder expansion board was intended to allow linear scales to be used with the system.

You could get AcornSIX and ENCEXP12 to run with motor encoder feedback. However, one of the control systems that is intended to ...

Even if your encoder supports that rate, I can think of no reason to do it.
The index pulse is a critical signal for the spindle encoder and you will be making it incredibly short. The better option is to keep the line frequency below 1.2MHz and make sure P323 is set to 127. This improves noise ...

The low speed filter is the right answer for all but obsolete, fringe use cases.

Encoders are normally powered by the AcornSix. Encoder output will not exceed its supply voltage, and the levels are typically much ...

Press Esc until the main screen is displayed. Turn off power.
DOS was not picky about shutdown. It did not have a multitude of files and processes open like newer operating systems.

H3 has open collector outputs, so you would need pull up resistors. For 5V signals, it is better to use H13 which has push-pull drivers.

The expansion board outputs can be used along with the other outputs.

SigmaWin+ 5 is still available:

A report created at the time of error is needed to troubleshoot.

Parameter 422 must be set to 1 to see inputs 65-80 on the PLC diagnostics (<Alt-I>) screen.
The PLCEXP1616 was detected and working when the report was generated.
The Youtube video is set private so we can not view it.

Thanks for pointing that out. I'll get the manual fixed.

P323 bits 5..0 correspond to MPU11 encoder plugs 6..1. Bit 6 is the MPG. This is the hardware level numbering, which differs from P308-315, where the MPG is 15.

I did notice that P323 has no effect on MPU13/HICKORY. The filters are ...

PLC customization could get a command to the second spindle. If the subspindle is required to do CSS or threading, that may not be possible at this time.
