The speed design of Stepper motor
When stepper motor started, there must be one process of up and slow down, the design of the speed is very important. If the design is not appropriate, will cause the wall of a stepping motor, step and speed slow.
Stepper motor speed process by a sudden jump frequency and litres of speed curve (slow down the process and vice), ideal for step motor speed curve exponential curve, according to the user's load relay, choice of different frequency and different index curve, in order to find a ideal curve, general need many times of commissioning. Stepper motor kick frequency shoulds not be too big. Index curve in the actual software programming more troublesome, generally good in advance after storage in ROM, the working process of the direct selection.
CP pulse of the design of the main demands of its, it is certain to should have (generally not be less than 5 mu S) pulse width, pulse sequence of uniformity and high and low level (negative pulse mode). Stepper motor commutator, must be in stepper motor speed down to stop before reversing. Commutation signals must be in front of the stepper motor one direction after the last of the CP pulse and direction of step motor next issued before the first CP pulse.
