For Leadshine, p981 delay is needed.

Check for a line like this in the PLC:
IF SV_MACHINE_PARAMETER_981 > 0 THEN MasterEnableDelay_T = SV_MACHINE_PARAMETER_981

If this has been dropped from the custom PLC, copy over the MasterEnableDelay_T related changes from the default HICKORY PLC.

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.

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 ...

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.

EtherCAT drives typically do not report an index pulse. The index pulse is synthesized from position. This is why the requirement is for single turn absolute encoders at minimum. If the encoder is incremental, the index pulse will not be repeatable across power cycles. ClearPath drive and motor ...

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.

I remember seeing that once before. I don't remember it having heatshrink, just twisted together and soldered wire.

The diode bridge may be damaged. 123 AC and 75 DC is more like half wave rectifier output, which may be possible if one of the diodes in the full wave bridge failed open. This is assuming you have CAPBRDLO. However, with a working CAPBRDLO, the 123 AC input would give about 172 DC, which would be ...

A problem with external wiring will damage the opamps (like IC22) that are exposed to the outside world.
If damage is only on internal parts (like IC20), the causes are typically as I suggested. If that does not apply to your situation, that is ok. I can only speculate based on past experience since ...
