How do two optical encoders synchronize the angle control

Photoelectric encoder is a commonly used angle measurement device, which can be used for angle control of robots, motors and other equipment. When it is necessary to control the angular synchronization of two devices, the following methods can be employed:

1.Synchronous signal: The synchronization signal of the two photoelectric encoders is connected together, and the angle synchronization control of the two devices is realized through the synchronization signal. This method is simple and easy, but it needs to ensure the accuracy and stability of the synchronization signal of the two optical encoders.

2.PID control: The output signal of the two photoelectric encoders is used as the input of the PID controller, and the angle synchronous control of the two devices is realized through the controller.

This method can adjust the parameters according to the actual situation, which can achieve more accurate angle synchronization control.

3.Encoder interlocking: The output signals of the two photoelectric encoders are connected together, and the angle synchronization control of the two devices is realized through the encoder interlocking.

This method can achieve more accurate angle synchronization control, but it needs to ensure the accuracy and stability of the output signal of the two optical encoders.

In short, for the angle synchronous control of the two photoelectric encoders, it is necessary to select the appropriate method according to the actual situation, and adjust the corresponding parameters and calibrate the accuracy to achieve a more accurate control effect.

This can be achieved with absolute encoders.

Summary. Hello, on the question you said. Does the optical encoder need to adjust the angle, yes? When the encoder outputs a pulse, the count of the pulses is the position, and the phase relationship of several pulses is the direction of rotation.

Hello, on the question you said. The optical encoder needs to be angled which bridge limb, it is needed. The encoder sensitizes the slow pulse, the count of the pulses is the position, and the phase relationship of several pulses is the direction of rotation.

Hello, you can check what my little sister just sent you.

Since I am not a professional electrician, please ask the name of the above driving appliance.

Hello,**Little sister here is not very clear, we have two pieces of equipment are produced by one manufacturer, and both have the same kind of failure: tensile servo motor alarm.

Hello, have you rebooted a bit.

Rebooting is useless. Hello, you want to restart the device, not that motor.

The incremental optical encoder is installed on the motor, and the speed and position of the motor are fed back to the servo drive or PLC, and then controlled by the PLC.

Incremental optical encoders are characterized by the fact that each output pulse signal generated corresponds to an incremental displacement, but this is not possible.

The output pulse distinguishes the increment at which position. It is capable of generating a pulsed signal equivalent to the displacement increment, which acts.

It is a method of sensing the discretization or incrementalization of a continuous displacement and the change in displacement (velocity) relative to a certain .

The relative position increment of the reference points cannot directly detect the absolute position information of the axis. In general, incremental optoelectronic compilation.

The coder outputs two pulse signals A and B with an electric angle of 90° different from each other (the so-called two sets of quadrature output signals), so that the square can be squared.

The direction of rotation can be determined on the spot. At the same time, there is a z-phase marker (indication) pulse signal that is used as a reference mark for each rotation of the disc.

For a week, only one flag signal is issued. Flag pulses are often used to indicate the position of the machine or to zero the accumulation.

1-1. The disc is engraved with radial translucent gaps of equal pitch, representing an incremental circumference between two adjacent translucent slits.

Time limit; The detection grating is engraved with two sets of light transmission gaps A and B corresponding to the code disc to pass or block the light source and photoelectric detection.

Light between devices. Their pitches are equal to those on the disc, and the two sets of translucent gaps are staggered by 1 4 pitches, such that.

The signal output by the photoelectric detection device is 90° different in phase. The encoder is detected when the disc rotates with the axis to be measured.

Without moving, the light shines through the transmission gap on the code disc and the detection grating to the photoelectric detection device, and the photoelectric detection device is output.

Two sets of electrical signals with a phase difference of 90° electrical angle similar to a sine wave, the electrical signal is processed by the signal of the conversion circuit, and it is possible.

The advantages of incremental optical encoders are: the principle structure is simple and easy to implement; The average life of the machinery is long, which can reach tens of thousands.

hours or more; High resolution; The anti-interference ability is strong, the signal transmission distance is long, and the reliability is high. The downside is that it can't.

The absolute position of the rotating shaft is read out directly.
