Stepper motor controller, stepper motor driver detailed technology
RELEASE：admin TIME： 2018-08-11 BROWSING： 949SECOND
Stepping motor is a kind of actuator which transforms electric pulse into angular displacement. Popularly speaking, when the stepper driver receives a pulse signal, it drives the stepper motor to rotate at a fixed angle (step angle) in a set direction. You can control the number of pulses to control the angular displacement, so as to achieve accurate positioning; at the same time, you can control the speed and acceleration of the motor by controlling the pulse frequency, so as to achieve speed control purposes.
1, automatic half current:
It means that the driver will automatically enter the half-current state when the pulse signal stops applying for about one second. At this time, the phase current of the motor is half of the running current to reduce power consumption and protect the motor. This function is set by the sixth position of the switch on the driver: 0 - no this function, 1 - has this function of phase memory (no time limit) drive. The generator is in a certain phase when it is cut off, and if it is different from this phase when it is powered on the next time, the motor will "jitter" for a while. In order to eliminate the jitter of the motor, it is necessary to remember the phase when it is cut off. This function is very important in some industries, and the memory time is unlimited.
2. The number of turns per motor is set:
(Subdivision Settings) Each type of driver has 16 steps (subdivision) optional, set by the first, second, third, and fourth bits of the dial switch on the driver. These 16 steps basically cover the user's requirements for the motor step, step settings must be in the driver is not powered up or has been powered up but the motor is not running before the effective driver output Current settings Each type of driver has 16 output currents optional, set by the switch on the driver's 7, 8, 9, 10 bits, the driver output three-phase sinusoidal current to the motor, the current size in the RMS nominal, for details see the drive output current settings section.
Control signal mode setting each type of driver has two control signal modes optional, set by the driver's dial switch on the 5th bit: CP / DIR mode: motor rotation direction by the DIR reversal level control, and step signal depends on CP. For example, the DIR for high-level motor is clockwise rotation, the DIR for low-level motor is counter-clockwise rotation. This way of commutation is called monopulse. The 5th position of the dial switch is set at "0"; CW / CCW mode: the driver receives two pulse signals (usually marked as CW and CCW), when one of them (such as CW) has pulse signals, the motor runs forward, and when the other (such as CCW) has pulse signals, the motor runs backward, which is called double pulse mode. The fifth bit of the switch is set at the "1" position.
3, protection function:
Over temperature protection, over current protection, under voltage protection, and protection of signal output.
