1, encoder shaft rotation change, encoder installation, the corresponding rotary shaft zero, the general increment and lap absolute value will use this method, while the sleeve-type encoder also use this method. Shortcomings, zero is not easy to find, low accuracy. 2, with the above method is equivalent, but the encoder shell rotation change, which is […]

For automation systems that use servo drives or variable frequency drives (VFDs), many customers do not understand the performance of their encoders. Some customers think that if they provide best-in-class encoders, the accuracy of the system will certainly be high. Sounds plausible? Yes, but there are other factors to consider. Encoder-based systems have three common […]

Input / output lag time, also known as system response time, refers to the time interval between the time when the input signal of the PLC changes and the time when it controls the change of the external output signal. It is composed of input circuit filter time, output circuit lag Time and scan work […]

Understand the shaft at the same time, you can know how he is processing and processing should pay attention to what the problem, these are in the process must be considered, the following Xingfeng yuan to tell you some of the reducer motor shaft processing Note: 1) In order to ensure the machining accuracy of […]

The encoder and the transmission shaft are both elastically connected to cushion vibration and concentricity deviation, but the concept of a shaft-type connection is different from that of a shaft-type connection. In principle, the amount of shaft-type connection elasticity is small (hard) , While the amount of shaft-type elastic connection can be hit. Sleeve type […]

When updating the operating system, Siemens PLC should always be updated with the latest version available for the relevant order number. Previous versions of the operating system were available as backups to allow the user to revert to the original version, although so far no such necessity has been found. The latest version of the […]
