VB and the development of wizards / Help with Input/Output control...

« on: December 16, 2010, 01:27:41 PM »

Dear All;

I am new on CNC machine and Mach-3. I have built a X-Y table positioner which we will be using to move antennas into predefined positions and making measurement with network analyser.  The X-Y table is to be controlled through Mach3. In practice we want to move the antenna in one position, waiting for the network analyzer to make the measurement, then moving the antenna to another position and repeat the measurement. We are thinking of having a sort of handshake protocol between Mach3 and the network analyser instrument.. so that Mach3 moves the antenna into a position and then sends a signal into the network analyser to start measurements. Once it finishes measuring, this sends a signal back into Mach3 so that it moves into the next position, and this cycle is repeated for all the positions.

The Mach3 is interfaced with DSPMC/IP controller which has lot of spare input and output ports that we can use for the communication. The problem is I am not familiar with Mach3 codes to output a signal to a port and wait for an input signal before it moves. I have read the G-code and M-code in the manual but this seems to be code related to the movement of the axis.  I appreaciate any of your suggestions.

Thanks in advance.

dspMC/IP Motion Controller / DSPMC AxisWorks Configuration

« on: April 06, 2010, 12:45:48 PM »

Dear All;
I am Xavi. I have posted on the forum few months ago about Interfacing OROM Servo Driver – Motor and DSPMC controller.   Following some suggestions and the user guides I have made all the connections for the two needed axis (X and Y).  I am trying to tune the motors with AXIS-WORK Rev 4.6 software but I am having lot of problems.  I don’t know for sure whether the problems are due to my connection or the chosen Axis work settings.  The motor encoder signal (passing through the servo driver) for axis X is connected to DSPMC (J6) Ch 0 and axis Y to Ch 1.

Using AXIS-WORK Rev 4.6 software Problem:
One of the axes (Y) is working fine, although I had to set the speed and acceleration to less than 6 and 10 respectively. Higher than this value the program gives a follow error.
AXIS – X
For this axis as soon as the PID is armed the motor automatically starts running and then stops and the program gives a follow error. Only when the feedback source is set to any channel other than where it’s connected, on the “configure control “option, the motor run when I press execute  but no changes on the position Axis display.  

I have tried solving it by connecting the motor encoder signal to channel 2, by changing the setting values (speed, acceleration, PID), or by grounding the analogue signal to motor (so that it never moves), but I still have the same problem (quick automatic start and stop).
I have swapped the axis connections between (axis X & Y) on the breakout board and found that whichever axis connected to DSPMC ch1 (J6) and analogue output 1(J4) the motor run fine without follow error on axiswork.  For the other I have problem.  

I wonder if some of you may have experienced this or have some ideas on how I might be able to solve it.  Looking forward to your replying.
 
PS: I have attached a .doc file of my connections. The pdf user guide of the servo and dspmc controller are on my previous post.

Regards

Xavi

dspMC/IP Motion Controller / DSPMC controller and Orom Servo Driver/Motor interface

« on: November 13, 2009, 06:29:17 AM »

Dear All;

My name is xavi. I am new in the forum I have posted this question on general topics but was advice to post under this section.
I am trying to set up an X-Y positionner, to move an antenna in X-Y plane controlled by a PC.  My main problem is on connection between the DSPMC/IP controller and the Omron servo driver.  I haven't used/build machine control tools/software before, but i need to set up the positionner so we can start with the practical experiment on the research we are doing. I have been watching the Mach3 video tutorial and also reading the omron servos and DSPMC user guides but there is no metion on how to interface them two, therefore I still have few questions.  So I am kindly open to any suggestion from you guys.  We have the following devices with us:

Mach3 Software

From Omron:
2x Omron Servo Driver   R88D UA12V               (one drive the x-axis and the other for y-axis)
2x Omron Servo Motor     R88M U40030VA S1   (one drive the x-axis and the other for y-axis)   

From vital system:
1x DSPMC/IP Controller from vital system  (is able to controll up to 6 axis as it say on the data sheet)
2x 7711 breakout board (to be connected j2 and J6 of DSPMC/IP)
1x 7535 Digital I/O board  (to be connected j4 of DSPMC/IP)

The connection between the 7711/7535 and the DSPMC/IP are straight forward following the user manual. The home and limit switches are to be directly connected (through the 7535) to J4pins of the DSPMC controller.   

Problems i am having...

1 -The user guide of the controller on the hardware connection the DAC and Amp enable output signal goes into the analogue servo amp.  In our case we will be using Servo driver How many connections from the DSPMC controller to Servo driver (SD) are needed to run the motor ?  (suppose 1 axis only) and which pins should I connect to on the servo driver CN1 port.

2 - The Servo Motor (SM) as encoder output can I connect it straight in to J6 of the controller (using the breakout board) or It is better to connect to the CN2 of the Servo driver (SD), and from the  SD CN1 pins 20 - 25 (the encoder output) connect to J6 pins of the DSPMC/IP controller ? 

I am looking forward for any suggestion on how to connect them two.

Thanks in advance
