Bridgeport Torq Cut 22 Retrofit

The drives internal settings are main gain, speed gain, integration gain. The main and speed are set to 40 (of 127) anything higher causes the motor to chatter. I have been all over the board with the integration and DMM told me it"usually doesn't effect anything".
Other than that, toque filter is off and there is an acceleration (smoothing) setting that is at 90 (127 is off, 1 is highest).

Here is some verbage from their website:
Main Gain: As load inertia increases, Main Gain should be increased correspondingly to make sure the servo has higher stability, increased stiffness and faster response. If set too high, high frequency noise is introduced because control loop frequency domain conflicts with torque servo loop. If set too low, servo loop may become unstable - low frequency oscillations introduced.

Speed Gain: As load inertia further increases, Speed Gain should be correspondingly increased to increase the servo stability. Speed Gain also has the effect of smoothing servo motor's motion. If set too high relative to load, servo response may become slower, high frequency noise may be introduced.

Integration Gain: Used to increase the servo stiffness and keeping servo accuracy. Generally should be lowered as load inertia increase as larger loads should not have high dynamic ability (rapid acceleration/deceleration). Higher integration gain will decrease the servo stability. For large inertia loads, integration should be decreased.

Edit, removed incorrect information

After dealing with the DMM servo issues of overcurrent at speed and delayed response in encoder feedback while in analog speed mode I have decided to take the project a different direction. I ordered a 7i78 to go along with the 7i92, 7i77 and 7i84. I have also installed the standard ISO Debian 10 Buster with 2.8. I will be reflashing the 7i92 with a different bit file later today to match configuration change. This is probably not the most ideal combo but it was affordable and I need to get the machine moving along. Once I clear the back log of work I will probably source some Yaskawa Sigma 5's and go back to analog control.

I would like to go over the math of the pulse settings to make sure I am in the right ball park.

Going over step/direction signal timing in the manual I have this page:


Max motor speed is 3000 rpm which makes it 50rps
Max pulse cycles read to be 500kHz which gives me 10000 us per revolution for pulses.
minimum pulse width is .8 us so it looks like to get max motor speed I would need 12500 pulses per revolution to achieve that.

The drive gearing can produce anywhere from 2000 to 65536 pulses per revolution.
Resolution wise this provides me with .000015ish" per pulse X/Y and .000009ish" in Z (geared 40 to 24 and 8mm and 5mm screws respectively)

Any thoughts on the math and the adequacy of the resolution? I probably wont be trying for full speed but closer to 90%.

A look at the ping times. First ping was .310ms curious why their is the occasional anamoly around .200ms

How is this project going? I have a TC22. Still using the old control!

Did you get rid of your original servo amps? I've been looking for a spare to use as a 4th axis controller.

Hello, I'm  new here. 
I have a Bridgeport torqcutt 22
The hardrive crapped out.
Does anyone have back discs where I can buy a new hardive and reinstall the software so I can be back up and running?
Any help would be more than appreciated!
