Encoder replacement & calibration on OSET TXP‑24 – anyone DIY’d this?

[John-Sammut]

I need to replace the encoder on a TXP‑24 due to false high temperature alarm.  

When replacing the encoder, one needs to calibrate it to the motor (Function 24) according to this youtube video by Oset:

Oset do not sell this tool to end users unfortunately. This is a blocker for users located in remote places.

Has anyone managed to DIY this step?

If you can determine who manufactured the controller, perhaps they would sell you the tool?

If the encoder is Hall-effect, there are a limited number of positions at which the rotor can "cog".  I would not recommend it, but trial and error is a possibility.

If the encoder is sin-cos, then there may be 256 to 4096 possible positions (depending on the resolution of the A/D converter).  Obviously not amenable to a trial and error solution. 

 

If you have not already removed the encoder, it may be possible to replace just the temperature sensor (thermistor).  In which case you would need a known good thermistor to measure its value or cannibalize a complete new encoder to get a thermistor.
