I am attempting to use an analog input from an ACC-36E in a UMAC rack to control the feedrate override on my machine tool. I am having a hard time getting the input into the encoder conversion table. Here is what I think I should be doing: Set up ADC inputs. Three single ended inputs in unipolar pairs ADC#1 and #9 and ADC#2 and #10. Only using 1,2, and 9. I5060=2 I5061,8=$400 I5081=0 ;ADC# 1 & #9 Unipolar I5082=1 ;ADC# 2 & #10 Unipolar M5061->Y:$003400,12,12,U ;ADC# 1 Unipolar M5062->Y:$003402,12,12,U ;ADC# 2 Unipolar M5069->Y:$003401,12,12,U ;ADC# 9 Unipolar M5070->Y:$003403,12,12,U ;ADC#10 Unipolar After doing this, I can see the value of M5061 change in the watch window as I turn the potentiometer. Now I am trying to run the first input through an exponential filter in the encoder conversion table and I cannot get a value from the output. i8011 = $178C00 ;Is this the right address to reference the data that I can see in m5061? i8012 = $D0350C ;Exponential filter referencing i8011 as input i8013 = $001000 ;Max change i8014 = $050000 ;Filter gain i8015 = $0 ;End of table I tried writing m7050 equal to i8014 to use as the buffered memory location for Isx93, but I just get the static number m7050 = 327680 Also, how do you scale your ECT result into a usable number for say, 0-150% override? I will also be implementing this process for my spindle speed override as well. Thank you, Casey

Turbo PMAC (only has serial and aux serial connectors) ACC-54E (USB1.1 only. Not functioning, looking for replacement) ACC-24E2A (x,y,z,spindle. All closed loop, using encoder inputs) ACC-36E (using for feedrate, spindle, rapid speed override) ACC-14E (2x 24ch OPTO22 attached by ribbon cable) I have a 2 channel ACC-24E that I could put in the space used by the ACC-54E. I eventually want to incorporate this card anyways because I have another axis I want to add. I could use the encoder input on one of those channels. I am using this in a CNC application. The unit is communicating with the PC via a vb.net UI. It does not require DPRAM to operate, but I wouldn't mind having it so I can get my axis position refresh rate up. Right now it is set at 500ms, but I think it mostly has to do with the vb program. What is the best communication time I could expect over serial?

My I/O is functioning properly. I haven't had a chance to use any outputs yet because I don't have my second OPTO board wired in yet.

Well, all of my I/O is already wired to the opto board, it is just a ribbon cable from the ACC-14E With a 100ppr hand wheel, if I used the IDC5B (.05ms switching capability) I could get 200 rev/sec of the hand wheel. If I used the IDC5D (1ms switching capability) I could get 10 rev/sec of the hand wheel. If my hand wheel Vout is over 4V, I'm going to try the IDC5B and see what that does.

Judging from the the OPTO22 page, I think I may need to get a couple IDC5B (4-16V) or IDC5D (2.5-28V) modules. I only have IDC5 modules. That would explain why I wasn't receiving a signal. The IDC5 has an input voltage range of 10-32.

Should I have any problems having an OPTO22 IDC5 module capture the A and B signals?

Do you have to tie the A/ and B/ to common? Right now I am not getting a signal from A and B.

mbalentine, Thank you for your explanation. You just confirmed that I have revised my code correctly. Another motion guru told be about the mvar definition rules. I placed all of my mvar definitions in my system initiation file that I just download and save to the PMAC. I used my PLC1 to set up my I/O as you showed in your other post. I haven't had time to download the new code to my PMAC, but I'm confident it will work.

I tried to download it from Pewin32pro2 without success. It still wanted to have a buffer open. I confirmed that my switches are set to the correct address. It is probably something very simple, but I can't find it...

I set my dip switches to the same as his example. I am using the Focus program to write and edit the plc. I'll try downloading it from Pewin32pro2.

This is probably more like a Delta Tau 101 question, but I haven't been intimate with my control in a while and I have forgotten something that is probably fairly simple. When I try and download my plc1, like the example above, it says that I need to have a buffer open first when it gets to the line "M6000->Y:$078F07,0,8 = $40 ;turn ON inversion setup function". How do I download this PLC to the controller? Thanks

Thank you for the excellent explanation! I am just getting my panel switches wired to the Opto board. I hope to get this to work this week. I'll post back with stories of success, or failure...

Hello, I was wondering if someone would be willing to explain how you set up an ACC-14E using an OPTO board as the input/output interface. I'm struggling with how to set up each memory address as either an input or an output. I think I gathered that you have to setup them up in blocks of 8 (either input or output). Do you have unusable inputs (cannot be used as outputs) if you have less than a block of 8? What I would like to do is set up my card to have 40 inputs and 8 outputs. Then I need to know what I have to change to invert individual inputs if I need to (NO vs NC switches). Thank you for your help. Casey

Does anyone have a working ACC-54E laying around that they would like to get get rid of? I need the faster data transfer speed and DPRAM of the USB or ethernet for a CNC mill setup. Thank you, Casey

Otto, I am putting together a CNC mill with similar components to yours. Would it be possible to contact you with some questions? Thanks, Casey
