Encoder manufacturers to teach you how to determine the encoder failure?
Encoder is converting signals or data preparation, available in the form of communication, signal transmission and storage of equipment.
What role does the encoder?
Contact output, using brush a brush contact conductive area or insulation area to represent the state of the code is 1 'or' 0 ';
Acceptance of non-contact sensor is photosensitive components or magnetic sensor, using photosensitive element to pervious to light and opaque to represent the state of the code is 1 or 0, through 1 'and' 0 'binary encoding physical signal will be collected by converted into machine code can read the electrical signals to communications, transmission and storage.
Encoder function: used for speed, position, test feedback.
For example: : the main shaft encoder feedback spindle speed, mainly in the processing thread is used.
Motor encoder: is a feedback unit, used to check how many performed motor pulse, so as to achieve the function of the accurate positioning.
About the encoder failure problems, in addition to the encoder itself, may also is what problem?
Around the encoder is a fine element, this first because the encoder causes more serious trouble, for example: if a large motor, electric welding machine has been starting form, isn't it the same pipeline transmission and power line, etc.
It's also important to choose what kind of output opposites that trouble, usually output with reverse signals of trouble is better, and A + to A - namely
8, whose character is combined with the power wire, rather than 5 thread (
A total of zero)
With the reverse signal in the cable transmission is symmetrical, troubled small, also can add in equipment under discrimination.
Is the encoder (
Electronic hand wheel)
There are good and bad, the encoder, electronic chips, internal circuit, signal output difference is very big, or else how to type a 1000 - line increment encoder can differ from 300 yuan to 3000 yuan so big?
Discriminant problem is for the encoder itself the most short way is to sweep method.
Mainly from the sweep,
Move out, closed, blocking)
Source of trouble;
Discrimination is for mechanical void cumulative error;
Discrimination is to control the system and the interface circuit of encoder mismatch (
The encoder fault selection)
Three aspects to confirm.
Shanghai electronic products is 27 years old, encoder manufacturers, specializing in the production of various kinds of rotary encoder, electronic research and development production of magnetoelectric encoder performance not easily affected by dust and condensation;
Its simple and compact structure, non-contact, long life, high and low temperature resistance, resistance to vibration, fast response speed and lower cost, looking for looking for electronic encoder manufacturers.
