Thanks,
I am familiar with stepper motors but my knowledge in servos is limited.
Can you explain how a servo drive works?
From reading the pixe datasheet, it looks like it wants a encoder input and the PID control lives in the pixe.
Does the servo drive only control the speed of the motors?
From looking at the yaskawa manual it has a tachometer input to the servo drive, So is the speed control closed loop also?
Also the speed reference input is 0 to +-6 for the yaskawa servopack, the output is jumper selectable on the pixe to -10 to 10 and -5 to 5, Are the voltages adjustable between these ranges?
Sorry for the million question.
Thanks for your help.
