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
