Build Thread for Bridgeport Torq-Cut 30

[CentroidFrog]

That is very strange.
The best thing to do would be for us to get your console in and see what we can do about it.
Please send an email to support@centroidcnc.com and request an RMA.
Please in the email include a link to this thread and the kit number or serial number for your Centroid control.

Thank you Centroid for the quick turnaround for the fix/replacement of the screen. It was kind of weird right? Now back to wiring for me.

Is there an update on the testing of a Delta C2000+ VFD with Hickory EtherCAT? I'm getting close to the point where I will start wiring the VFD. It sure would be nice to just plug it in with one cable.

I made a lot of progress this weekend but ran into an issue. I got all the servo motors installed and wired but ran into a bit of a problem. One of the Leadshine EL7 encoder cables seems to be bad. I thought I started seeing this when I did the bench test but ignored it for the time being. The problem is, I can only clear the 153 error code if I do a driver reset and then do a complete tune. After I save the parameter and restart the drive, it reverts back to a 153 or 150 error code. I swapped out the encoder cable with the two other drives and had the same issue with each drive it was attached to.

Please check inside the battery box and confirm that the battery:
1. Is present. If the battery is not there, then it was missing from the shipment or possibly loose in the packaging materials. Check the packaging and then contact Centroid support directly via phone or email if not found.
2. Has somewhere from 3.3 to 3.6 volts across it. If the battery voltage is low, then it needs to be replaced. This should be unlikely with how new everything is but can happen.

If it is neither of those, then the cable itself may be bad. Please contact Centroid support directly via phone or email.

Thanks for the response. I did check before I originally posted to see if it was missing the battery after reading a similar post on the forums. I did not however check the voltage across the battery but will do that this evening. I do think there is something wrong with the cable because at one point when I had all the error codes cleared and I gently moved to cable to tightly up the excess cord, it instantly threw and error code. I will check the battery voltage first though before I return it.

I got a lot accomplished in the last week. The replacement Leadshine encoder cable did the trick. It did have a battery, and the voltage was good so it looks like it was just a bad cable. With the cable replaced and the drives tuned, I moved on to installing the Delta C2000+. VFD. I was a little confused at first with certain parameter settings but finally figured it out. Just to note, for a Yaskawa UAASKA-06 spindle motor, parameters 01-00 (max frequency) and 01-01 (base frequency) are both 266.67hz for a 8000 rpm spindle. For the spindle encoder, I decided not to use the encoder built in the Yaskawa spindle motor but used the other encoder that is belted 1:1 to the spindle. I replace the original belted encoder with a programmable encoder and it is programmed for 2250 lines which is max for the PG01L card (300kHz max) in the Delta VFD at 8000 rpm. I have the encoder attached to the Hickory board and the rpm readout CNC12 matches the Delta Drive.
The next step is to connect the Hickory spindle control to the VFD and the tackle the tool changer. I'm sill a little unsure about the tool changer wiring.

If anyone has any tips and trick for a Bridgeport umbrella tool changer, please chime in. I'm not sure how the carousel in and out brake gets wired to the Hickory.

Lastly, I'm a little confused how the z-axis servo-motor brake is suppose to work with Hickory. I have it wired to relay board 9 per dwg. S14219r3, but I still need to turn it on and off manually if I want to jog the Z-axis and if I want to shut the machine off and not have the z-axis drop.

Hope everyone is having a great weekend.

If anyone has any tips and trick for a Bridgeport umbrella tool changer, please chime in. I'm not sure how the carousel in and out brake gets wired to the Hickory.

You will probably want to consult with Centroid if you are starting from their factory-standard umbrella ATC program, and especially if you are trying to maintain compatibility with the Hickory Wizard.

In general, the Bridgeport tool arm brake should be powered (released) whenever the arm needs to move, either in or out. If you do not want to configure a dedicated PLC output for that purpose, and add a line of PLC logic for it, then you could make your arm-in and arm-out outputs operate DPDT relays; then use one pole of each relay to power the motor in the respective direction; and the other poles (in parallel with each other) to power the brake release.

I maintain my own PLC programs for Torq-Cut machines, with a dedicated output for the tool arm brake release. I also include logic to ensure that the arm motor is not powered for more than a couple seconds at a time, even if the arm-in or arm-out movement fails to complete. This ensures we do not burn out the motor if there is an obstacle in the way of the carousel, or if the carousel-in or carousel-out sensor has failed.

PM me if you are interested in purchasing my Torq-Cut Hickory program and macros, vs. adapting the factory ones for your use. Note, however, that mine do not currently support XY diagonal jogging, separate Rapid Override controls, or the SSV/FRV features.

Lastly, I'm a little confused how the z-axis servo-motor brake is suppose to work with Hickory. I have it wired to relay board 9 per dwg. S14219r3, but I still need to turn it on and off manually if I want to jog the Z-axis and if I want to shut the machine off and not have the z-axis drop.

That depends entirely on what PLC program you are using, and how you are trying to "jog" the Z axis.

If you use a PLC program that includes a line similar to:

Code: Select all

IF SV_Z_AXIS_VALID && SV_Z_AXIS_POWERED THEN (ZBrakeRelease_O)

Then the brake should be released whenever you enable Z through the CNC12 software (e.g. by jogging it, or by starting a CNC cycle such as homing); and the brake should be reapplied when you disable Z (e.g. by pressing emergency stop, or shutting down CNC12).

With that type of brake control, it will not be automatically released when you try to use the drive itself, or LeadShine PC software, to enable and jog the motor without involving CNC12. Therefore, on a machine like a Torq-Cut that has an unbalanced Z axis and linear rails, testing or tuning the servo drive entirely through the drive manufacturer's PC software is problematic.

On a separate note:
I don't think you need the banks of current-sinking PLC inputs (on Hickory INP25-INP32). The prox sensors on Bridgeport Torq-Cut machines always seem to be NPN.

Centroid's generic umbrella-ATC schematics always include a bank or two of current-sinking inputs, because the Taiwanese machines their OEM customers import typically have PNP sensors on the ATC components.

Thanks cncnw for the helpful info. I need to digest it and decide how I plan on tackling the tool changer. I'm finishing up the spindle to Hickory wiring now which will leave the tool changer my last challenge. I haven't dug into the PLC programing too much yet but plan to soon.

I started getting into the PLC and the Hickory Wizard tonight. I'm running v5.30 and I figured I'd start off simple and add the Z axis brake release to the PLC via the Wizard. When I went to add ZBrakeRelease to Output09 (per s15219r2), it wasn't an option. the only options were A, B, C, U, V, and WBrakeRelease. There is no X, Y, or Z. What am I missing? It shows it to be an option in the "centroid_wizard_input_output_canned_PLC_functions.pdf" manual.
