The tool post encoder is a key accessory for CNC lathes. It can feed back the working position of the lathe tool post to the CNC system to realize automatic switching of the lathe tool. Tool holder encoders are widely used in CNC machine tool holder equipment. Encoders will inevitably fail during use. Tool holder encoder manufacturers analyze common faults for us and prevent us from encountering faults.
1. Encoder fault: it refers to the fault of the encoder's own components, which causes it to fail to generate and output the correct waveform. In this case, you need to replace the encoder or repair its internal components.
2. Encoder connection cable failure: This type of failure has a high probability of occurrence and is often encountered during maintenance, and should be a priority factor. Usually the encoder cable is open, short-circuited or poorly contacted. At this time, the cable or connector needs to be replaced. Special attention should also be paid to whether the cable is not tightly fixed, causing loosening and causing open welding or disconnection. At this time, the cable needs to be clamped.
3. Encoder +5V power supply drop: refers to the +5V power supply is too low, usually not lower than 4.75V, the cause of the too low is the power supply failure or the power transmission cable resistance is too large and the loss is caused, then the power supply needs to be repaired Or replace the cable.
4. Absolute encoder battery voltage drops: This type of fault usually has a clear alarm. At this time, the battery needs to be replaced. If the memory of the reference point position is lost, the operation of returning to the reference point must be performed.
5. The shielding wire of the encoder cable is not connected or falling off: This will introduce interference signals, make the waveform unstable, and affect the accuracy of communication. It is necessary to ensure the reliable welding and grounding of the shielding wire.
6. Loose encoder installation: This kind of failure will affect the accuracy of position control, resulting in excessive position deviation during stop and movement, and even an overload alarm of the servo system will be generated as soon as the machine is turned on. Please pay special attention.
7. Grating pollution This will reduce the signal output amplitude, so the grease must be gently wiped off with absorbent cotton dipped in absolute alcohol.

Introduce the difference between Canopen bus and Canopen absolute encoder
Controller area network is one of the most widely used open field buses in the world. As a remote network communication control method with advanced technology, high reliability, complete functions and reasonable cost, CAN bus has been widely used in various automation control systems.
For example, the encoders inside printers and magnetic card machines have a simple structure, and many shells are not available. There is almost no need to talk about temperature, dustproof, waterproof, electromagnetic compatibility, and the price is extremely cheap.
What problems should be paid attention to when using CANopen absolute encoder
What problems should be paid attention to when using CANopen absolute encoder? CANopen absolute encoder is a device that converts changes in mechanical angle physical quantities into electrical signals.
How to use industrial Ethernet encoder to accurately measure speed
How to use industrial Ethernet encoder to accurately measure speed? In the use of encoders, angle or linear distance measurement is an important aspect, it can also be used for speed or linear velocity measurement. When the industrial Ethernet encoder rotates faster, the pulse frequency increases at the same rate.
Briefly describe the installation process of the servo encoder
Servo encoder is a kind of sensor installed on the servo motor, used to measure the magnetic pole position and the rotation angle and speed of the servo motor.
Understand where the servo encoder coupling should be changed in use
When choosing an encoder coupling, customers will consider its performance, service life, reliability, and whether there is noise. But there are still some unsatisfactory places in use, so where should the servo encoder coupling be changed in use?
