 The chart above shows the controller’s maximum controlled speed as well as the maximum speed obtainable for a particular leadscrew. ​ The actual minimum speeds obtainable will also have something to do with the motor-controller-bearing dynamics. ​ It is this issue that we examine next by looking at actual low speed motion histories. The chart above shows the controller’s maximum controlled speed as well as the maximum speed obtainable for a particular leadscrew. ​ The actual minimum speeds obtainable will also have something to do with the motor-controller-bearing dynamics. ​ It is this issue that we examine next by looking at actual low speed motion histories.
