OK Not sure about the spindle now. On the Control Configuration the
Spindle High is 4200
Spindle Low is 500
The following parameters are
33 is 1
35 is 0
64 is 0
65 is -0.125
66 is 1
67 is 1
78 is 0
278 is 0
Auto/Man button is lit on the Spindle Control
Sometimes I get "5040 Specified Spindle speed is "less than symbol" than minimum spindle speed.
So not sure why parameter 35 pairs the X axis and tried to look up 5040 in the operators manual with nothing found.
Still getting used to searching thru the manuals, but making progress.

Parameter 35 is the spindle encoder axis number. What encoder port did you plug your spindle encoder into on the AllInOneDC? Normally that is encoder port 6. If you put "1" into P35, it will measure the speed of your X-Axis motor. If you put 2 into P35, it will measure the speed of your Y axis motor.

P35 should be the same number as the port you plugged your spindle encoder into.

There is no encoder on the spindle motor, which means parameter 35 should be set to 0. That is the way I understand it. By the way what happens if a program calls for a spindle speed that is faster than the machine is set for in the configuration window? For example this machine has a high spindle speed of 4200 rpm , but on of the programs has a spindle speed of 4600 rpm.

The warning message "SPECIFIED SPIN SPEED < MIN SPIN SPEED" means that you programmed, or otherwise requested, a spindle RPM less than the minimum that you set on the Control Configuration screen. The spindle will run at the minimum allowed RPM, rather than at the requested RPM.

500 RPM seems like an unnecessarily high lower limit for high-range speed. But, if you want to force yourself to shift to back gear for all speeds that are achievable with back gear, then that is a way to do so.

If your machine's maximum speed is 4200 RPM, and you program 4600 RPM, it will run at 4200 RPM. There is no warning message in this case.

The Control Configuration screen is set to 4200 and 500 rpm. The original machine had a Vari-Speed drive which is the variable pitch pulleys. They have been replaced with a cogged belt and 1:1 cogged pulleys. The original speed ranges are 60 to 500 rpm and 500 to 4200 rpm. So I figured 500 and 4200 would be the proper speeds for the Control Configuration window. Also the Hi and Low speed lever has a electric switch, does that have any indication on the screen for Hi or Low speed.
Thanks

If you wired your low-range switch to an input (usually INP13, but it could be different depending on your installation and PLC program); and you are using a PLC program that recognizes a low-range switch, then the PLC will automatically compensate motor speed and direction depending on which range it is in.

OK so I had disconnected the wires from the VFD to spindle control on the ALLinone at some time in the past.....and forgot about them. So they got reconnected. Bad on me. So anyhow I did notice the speed ranges were opposite so I reversed the connection on the limit switch for high and low range and that corrected that. The thing I just realized the direction of spin wasn't confirmed, so today I will fire it up and check that out.
Thanks
