Q:What are the six wires of the step motor

1, single polarity stepper motor, two coil, there are five or six lines, namely in the middle of a coil adds a tap, five line can be seen as six lines between the root of the two coil line and together. Because in the middle of a coil with the tap, half of the current in a coil take different flow, but then just use half of the motor coil. 2, a bipolar step motor is an electric motor with two coils and four lines. The current is either positive or negative in the two coils, so it is called bipolar. 3, bipolar stepper motor and single polarity of stepper motor, is due to a few decades ago, stepper motor drive circuit is more expensive because it is over, if using bipolar drive circuit, the circuit a lot more expensive than single polarity, so many years ago, single polarity of the stepper motor. But as the cost of stepping into the motor drives lower and lower, coupled with the emergence of some very cheap drive chips, the dual-polarity motors are more used. At the same time, the bipolar motor because a forward and reverse current flow through the circle line, the application of high efficiency, most of the time is because of the single polarity motor USES only half of the coil, so the efficiency is low. But in places where costs are stricter, single polarity motors are widely used.

Q:What is the connection between PLC and motor, including ordinary motors and stepper motors. What is their power supply?

PLC links with ordinary motor, controlled by the PLC contactor, contactor control motor, or with PLC control inverter, the inverter control motor, power inverter supply, step motor (including servo), controlled by the controller, the power source controller, PLC controller.

Q:How to solve the vibration problem of stepping motor??

The breakdown of the drive is not good, and if it is subdivided, you can either reduce the segmentation or increase the pulse frequency.

Q:In addition to using the PLC to step the pulse signal to the motor controller, what els

The controller, control card, and MCU can send pulse signals to the motor controller

Q:Can a stepper motor be converted to servo motor without changing the PLC program?

Not very good change, can change PLC procedure only, but change also not very, should be feasible.

Q:Can the numerical control system for stepping into the motor can be used for private motor

It's okay to take a step in, it's a little bit more accurate because the server itself has a feedback system. Servo parameter is set to the position control mode, then good pulse signals and direction at the same time is set up pulse + direction or double pulse patterns (according to the original step mode) if the steering is wrong, can pass parameter adjustment. The electronic gear is then calculated and adjusted to make it precise. The voltage of the servo actuator may not be the same as the step forward, and you will need to replace the driver transformer if necessary

Q:How do you change the direction of the step motor

The step electrical and electrical machinery is controlled by the pulse frequency. There are two modes of control, single pulse mode. This is the high and low level control, high level control in one direction, low level control in the other direction. This is also the current way of controlling stepping motors.

Q:Does the stepping motor start a lot?

Look at the multi-power step motor, pulse drive, 5V voltage, some under 200mA

Q:What is the meaning of the step motor drive half flow setting and attenuation setting?

The current set 0.5 or 0.8 A, the rest set 50% and half stream, the fine fraction if the speed is slow, set 16 segmentation. The attenuation setting is also set up 50%. The mode of attenuation is the result of the four transistors that have been advanced or delayed in the sequence of the driver output of the step motor. Decay time setting refers to the stepper motor stalling after a few seconds (average 0.5 3 seconds), rated current of the motor supply attenuation, without attenuation 75% 100%, 50%, 25%, and several. Mainly is to reduce the motor stopped noise, be quiet after the motor has stopped, and energy saving. Usually the above function, if the stepper motor drives, motor stop automatically after attenuation function of rated current, it could really set the motor stopped, how many seconds delay (s) into the attenuation function automatically. Stepper motor, is actually a generator, spinning process will produce inductive electromotive force, when applied voltage disappears will sub there will be a braking effect on both ends of the motor winding, not short sub is inertia. This is reflected in high speed characteristics (no braking high-speed connection) or low speed properties (vibration).

Q:Remote control step motor to solve the problem

First of all, to use keil to microcontroller programming, stepper motor after their chosen model, connected to the drive, the connection to see drive specifications, major difficult in programming, define your own p0, p1, p2 or other mouth as pulse and direction control. The step motor is an open loop controlling element which converts the electrical pulse signal into angular displacement or line displacement. In the case of the overload, motor speed, stop position depends only on the pulse signal frequency and pulse number, and not affected by load change, when the stepper driver receives a pulse signal, it is driving a stepper motor according to set the direction of a fixed Angle, known as the "step Angle", its rotation is based on the Angle of the fixed step by step. It can control the amount of angular displacement by controlling the number of pulses, so as to achieve accurate positioning. At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency to achieve the goal of speed adjustment.
