a flexmotion-6c and a 7344 plugged in the same computer, now with the step output to drive the stepper motors, the 5th axis of flexmotion-6c and all the axises of 7344 have this problem! In the max, i have appointed the speed, but the velocity shown in the max will change ceaselessly while the speed of the motor is really changing in such a big scope.
All the motors are open-loop. the firmware is 5.0. In comparation, another two 7344 are pluged in the second pc, all the axises work very well with all the same parameter settings, except the 6.0 firmware.
I have monitored the step output of the axes with a oscillograph. The pulse of axis with problem have the variable frequency, while the right ones have the fixed frequency.
So, maybe where the problem is?
Thanks!
