Hello! I am stuck with a servo motor issue that I have no idea for the cause. Machine has 5i23 and 2x 7i39 cards with total of 4 servo motors. I set it up 2 months ago and it was working correctly. Machine was idle for few weeks until now. Motors 0, 1, 2 are working correctly, motor 3 does not move, pid 3 gets reaches its max value as soon as I try to jog the motor.
1) I swapped motor and feedback cables of motor 2 and motor 3 (they are on the same 7i39 board). Problem moved with the motor, so 7i39 board is fine. 2) I attached motor 0 to motor 3 cables on machine, motor 0 did not work; I attached motor 3 to motor 1 cables, motor 3 worked correctly; both of these things tell that problem is somewhere in motor wires; 3) so I took multimeter, and checked motor power cable between motor plug and 7i39 plug - all the lines are where they are supposed to be; 4) I tried to spin the motor in "bldc config=n" with bldc.value 0.15 and bldc.frequency explicitly set at 0,15 and 3 respectively (motor should slowly rotate as soon as pwmgen is enabled), but it moves just a very little and stops; The drive is ok, motor is ok, cable is ok, but now they are not working together. Everything was fine few weeks ago. I would appreciate any suggestions, what else can I try to understand, what exactly is wrong. -- Viesturs If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
