How To Select Encoder?

In the industrial field, any motion control process needs to be provided with reliable feedback by sensors. The fanuc encoder is part of the machine that provides feedback. When the fanuc servo motor encoder is running, it can receive the motion signal and convert it into an electrical signal, which can be read by some motion control system. Then, the motion control system can use various parameters on the signal controller, such as speed, direction and position. The precise performance function can be generated between the machine and the controller through the encoder signal.

Selection Requirements

When choosing an encoder, you need to consider some basic problems. First, you need to determine the application control specification. Encoder has a wide range of applications, from very simple machines to complex machines. Some machines only need simple position control or speed control, so the accuracy required is low. Some complex machines may require more advanced feedback. Therefore, when selecting an encoder, it is important to understand its specific purpose.

Another thing to consider is the properties of the fanuc motor encoder. Usually, this involves the number of rectangular pulses of the motor. The number of pulses is transmitted by two channels, and the phase shift of these two channels is one fourth of the pulse length. In this way, the rotation direction of the motor can be detected using four different states of each pulse. These four pulses represent the actual resolution. The fanuc spindle encoder can detect motion, which means you need to determine whether your application needs a simple encoder or a complex encoder that can detect extremely accurate position or speed.

Other factors also affect the resolution. Mechanical layout is a potential factor affecting encoder resolution. In addition, the physical fundamentals of optics, magnetism and inductance can also play a role in the resolution of the fanuc pulse coder.

Environmental factors also need to be considered when selecting encoder. If the fanuc new original encoder is exposed to dust, corrosive chemicals and a large amount of moisture, it is necessary to consider adding shielding to the encoder. As the incremental encoder is an electronic device, it is easily affected by temperature, impact, vibration and other factors.

Type Of Encoder

The types of motion that each encoder can monitor are also different. There are usually three kinds: linear motion, rotary motion and angle.

The linear encoder can be used to monitor the motion of linear objects and encode their positions. The sensor can convert the coded position into analog signal or digital signal. The signal can then be decoded by the motion control system.

For rotating objects, a rotary encoder can be used. The rotary encoder can provide feedback on the motion of the rotating object or device and convert the angular position of the moving shaft into an analog signal or a digital signal. The control system can determine the position or speed of the shaft through this signal.

Angle encoder is similar to rotary encoder, but it can provide better accuracy. It can measure the angular position of the rotating shaft. The rotator is equipped with a grating that works with the photoelectric sensor of the stator. Since the optical technology depends on the tightly constrained rotation of the rotor relative to the stator, the angle encoder can keep the two parts of the bearing concentric.
