Stepper motor controllers, stepper motor driver technical details（1）
Stepper motor is an electric pulse into the angular displacement of the actuator. Popular point: when stepping the drive receives a pulse, it drives stepper motor rotates along the direction set by a fixed angle (that is, step angle). You can control the number of pulses to control the amount of angular displacement, so as to achieve accurate positioning purposes; and you can control the pulse frequency control of motor speed and Acceleration, so as to achieve the purpose of speed.
1, automatic half-current:
Is refers to drive in pulse signal stop imposed 1 seconds around, will automatically into half current state, then motor phase current for run Shi of half, to reduced power and protection motor, this function by drive Shang of dial bit switch of 6th bit set: 0-no this function, and 1-has this function phase memory function (no time limit) drive power Shi in a a phase, next added electric Shi if and this phase different, motor on will "jitter" about, to elimination motor jitter on must put power Shi of phase memory live. This feature is very important in some industries, memory time is unlimited.
2, the number of motor steps per revolution set up:
(Fine scores set) each species model drive are has 16 species step number (subdivision number) can selected, by drive Shang of dial bit switch of 1th, and 2, and 3, and 4 bit set, this 16 species step number basic covers has user on motor step from of requirements, step number set must in drive not added electric or has added electric but motor not run Shi only effective drive output current set each species model drive are has 16 document output current can selected, by drive Shang of dial bit switch of 7th, and 8, and 9, and 10 bit set, Drive three-phase sinusoidal output current to the motor current nominal size to valid values, see iridescent drive output current setting parts everywhere.
