This note is about an absolute encoder from TR, model number: ZH65M-175-00003.This is an encoder with Profibus-DP communication signal, and I spent a lot of time not finding a manual for it. In the end, I could only spell out a parameter data through fragmented information. This product should be discontinued.
The customer is very anxious, has been in the major websites query for three days, still can not find the supplier. Finally decided to entrust us to do non-standard customized replacement, but the customer did not have any information, only a set of models. I finally queried its real parameters through the combination of Google+Bing+Yandex.
Parameter introduction of ZH65M-175-00003
Profibus-DP communication signal, resolution 4096*4096, blind hole type flange. The difficulty is in this flange size, without the manual, it is impossible to determine the size of the shaft hole. Ask the customer also no original can be measured, finally found this size on the Internet: 14mm.
With these basic parameters, we can customize the new encoder based on them.
Introduction to Customized Alternatives
For Profibus encoders, we have a complete solution. For the parameters listed before, we can make a one-to-one replacement product. We are using 58mm aluminum alloy housing to achieve this, and the above picture is the actual picture.
Every time I come across a Profibus encoder, I feel like there's nothing to write about. Resolution, mounting dimensions, that's all the data. Since Profibus encoders are one of our main products, they are so familiar that there is no room for clarification. For the replacement of the ZH65M-175-00003, it is enough that the parameters are exactly the same. Of course, there is still a little difference, namely the outer diameter. The outer diameter of the original encoder is 65mm, our encoder is 58mm, but this data does not affect the application of the product.
caveat
A cliché that needs to be clarified here is the application of encoder GSD files. As a Profibus encoder, the GSD file is a necessity. This point should be made clear, because some traders do not understand this, think to buy back to install can be used. In fact, it is not, it needs to be used through the PLC configuration.
Therefore, the first step is to make sure that the technician can control the encoder through the PLC. This is important. Be sure to confirm this in order to save unnecessary trouble.
