2.1 When is it required to apply the current reduction?
Current reduction is required when the user wishes to save energy or reduce
motor heating. It can be used as a safety function for torque reduction in holding
positions.
2.2 When a reference move is required?
After powering up a step drive or when slippage (loss of steps) has occured.
2.3 What dictates the maximal speed of the step drive?
The maximal speed of the step drive is determined by its electrical and
mechanical parameters, as specifified by the manufacturer. One consideration
for selecting the speed limit is the service life of the ball bearings for the motor.
2.4 What should be done to decrease slippage?
To decrease slippage, hard acceleration and overloading the motor should be
avoided.
2.5 Calculate the drive resolution in the full-step mode
According to the lab guide:
,,The distance the slide moves per mm positioning path (drive resolution) is equal to the ratio between
