Re: Hardinge CHNC4 Retrofit
Do you mean INP3, on the Alt-i display on the computer screen, is flickering between green and red? Or do you mean that a physical LED on the Allin1DC board, which happens to be near the limit defeater DIP switches, is blinking? If the latter, that has nothing to do with the limit switch defeaters. ...

Re: +\- 10vDc PLC spindle code for ALLINONEDC
Assuming you only want to use it for speed control, then that should work (output a value from 2048 to 4095 for 0V to +10V). My standard code is like this (having previously set "SpindleAnalogBipolar_M" per a parameter selection). ;Convert RPM to 12 bit value IF True THEN TwelveBitSpeed_FW...

Re: 6 VDC Coolant pump
No, but you don't get power for the coolant pump "out of the Allin1DC" in any circumstance. You need to find and install a suitable DC power supply, and a relay to switch it with. Then you use the Allin1DC output relay to switch the coil of the relay that in turn switches power to the pump...

Re: Multi Spindle CNC Router control options
Wiring the analog signal to two or three VFDs in parallel is generally not a problem.
The maximum load on the analog output for most Centroid boards is 10mA.
Typical VFD analog input impedance is 10K or higher, so the draw at 10V would usually be ca. 1mA per VFD.

Re: VFD control voltage
If you disconnect the Acorn's analog signal from the VFD, and give a full-speed command, do you again get +10V? If not, then the Acorn's analog output section has probably been damaged in some way. If you do get +10V when disconnected from the VFD, then something about the VFD analog input is puttin...

Re: VFD control voltage
Does your VFD really call the analog input terminal "AO1"?
That is a more common naming pattern for an analog output (e.g. speed or load monitor signal).

Re: Multi Spindle CNC Router control options
Helical arcs in G17, using W instead of Z, should work just fine.
Arcs in G18 or G19 will not work with the W axis. You would have to get your CAM software to post them as a series of short G1 moves instead.

Re: Help with tool change macro
You might also want to configure the machine to home using the monitoring switch as a home switch, so that machine zero on the Z axis is just below the carousel. In your tool-change macro you can set the Z+ software travel limit to a non-zero value (e.g. +2.10") to allow movement above machine ...

Re: Help with tool change macro
In that case you probably want your PLC program to trigger an immediate Fault if the monitoring switch is tripped and the spindle zero-speed signal is not closed.

You will have to look at what value you have in Machine Parameter 18.
