Hardinge CHNC4 Retrofit

[centroid467]

Take a look at page 340 in the lathe manual. You'll need to make sure you have a Pro or Ultimate license and then set parameters 218, 348, 349, 350, and 411.

Making a report before doing changes is a very good practice.

Parameter 218 should be set to 3, not 4.

You should have the USB dongle already plugged in, and maybe have the WMPG turned on, before you launch the CNC12 software.

If possible, plug the USB dongle into a USB port in the computer itself, and not into an expansion hub.

You have a report from last Saturday saved earlier in this thread.

I would like to activate the contactor so the voltage supply for the servo drives is available. I could bypass it but would prefer to switch it on/off. I didn't think it would be too difficult but I seem to be missing something. per the drawing It should be a 24 VDC contactor. I thought that 24 vac would be coming off the transformer red/brn wires which would activate the contactor...

[cncsnw]

Typically it would be a 24VAC (not DC) contactor. Yes, it would use the 24VAC secondary from the transformer (RED and BRN).

In a typical Allin1DC installation, the contactor coil is powered through PLC OUT1 (first relay on the Allin1DC outputs header) and the emergency stop button.

A typical Allin1DC PLC program will close OUT1 if there are no fault conditions, no stall conditions, and the emergency stop input is closed.

If your OUT1 is open, even though you have released the emergency stop button (closed both its circuits), then there is a continuing fault or stall condition. With luck there will be a message in the message box telling you what it is.

I don't have the control installed yet, I wanted to jumper a couple wires to activate the contactor. I got it. I wanted to check the voltage for the servo drives without having to hold the plunger on the contactor... it's about 130 vdc.
I'm slowly removing the old controls from the cabinet; SERVO 1. Computer, PLCIO2 and power supply and the shelf that the computer sat on...I don't want to use the rolling cab, but for the near term it will provide a protected place to keep the Allin1dc.
So far splicing of cables has gone well, I'm zeroing in on a connector for the 30 pin cable, if I run a separate cable for the the VFD I could use a set of DB25 connectors...as I have mentioned wiring is my worst nightmare but with these style connectors it should be a bit more correctable

Next I want to connect the VFD and activate the servos via the Alin1dc, which is "on the bench". I will also try to organize the cabinet to mount the Allin1dc, PLCADD1616 and new power supply. My initial thought is that I will only use about half the space inside the cab.

That will be about all I can do before being away for the month of October.

Step 1

I’d like to confirm the servo motors I have to make sure the switches on the Allib1dc are set correctly. There is a Centroid P/N 7457 and torque rating of 16 in-lbs shown on the motor. I can’t see an amperage rating. Currently the switches are DOWN - UP for all axes

Once you determine the amperage rating of your motors, pg.3 of the AllIn1DC install manual shows how to correctly set the switches.

Appendix C of the ALLIN1DC install manual shows that 16 in-lb Glentek and 17 in-lb Redcom motors should use the 9A setting.

Edited:
You can find a more general guide with the switch positions on pages 41-42.

The only way to get 100-110VDc from AC is a transformer. It you replace your servo motors with 170VDc rated motors, you can use direct rectification of 120VAc and do away with the transformer.

I went back to revisit this. I had a couple things wrong ,,,. My servo motors are rated for 180 VDC max - I see centroid has a bridge rectifier that will get me ~155 VDC @110 VAC. My AC power is usually 123-ish so that put me closer to the 180 Max. My calculation is just a ratio using the 155 @ 110= X @123 >> 173VDC
