I'm now turning the drive down to 6400 Means I send a pulse to stepper motor drives It divided it into 6400 pulses to the stepper motor or I send 6400 pulses to stepper motor drives It sends a to stepper motor?
Both of the master's understandings are completely wrong! 6400 means that the controller (controller refers to the movement control CARDS, PLC, CNC system and other device can send pulse) after sending 6400 pulse, the motor can turn a week. This will adjust the system's accuracy and improve the stability of the motor.
For example: A TD7578 two-phase stepper motor drives, subdivided into 6400, then drive to step away from the Angle of 32 subdivision, assumes that the driver is 3 A stepper motor, gear drive are also set in 3 A, each segment of the current drive is: 3/32 = 0.09375 A The actuator receives A pulse instruction, which assigns the 0.09375 A current to the step motor. Because this is DSP digital drive, its algorithm is more accurate. If an analog control drive is a value close to the value, the motor generates a different electric current. In fact, the actuator is a low level signal that controls the switch of the step motor current, which makes the step of the motor work step by step.
It's useless to know the diameter of the guide. Track pitch, it's easy to look up to the (mostly pitch also called lead), such as your screw pitch is 5 mm, means a revolution of the screw, the load to be able to walk 5 mm, then you turn 6400 pulse motor for a week. The distance of each pulse is 5/6400, and if there is a reduction ratio I, the above value is divided by I.
