Why don't you contact Renco and ask them for a suitable replacement??
Hi guys;
I use Renco encoder type RCH20D-2000/3-8-5/0-LD/VC-M6-S for the servo motor, however Renco stop producing this type of encoder, could help to suggest any replace type of eoncoder. The detail data please refer to attached file. In my case, the pin number 8 is a special signal ABS, which use for commutation.
Tks and with best regards

Why don't you contact Renco and ask them for a suitable replacement??
However i need to pay Renco 3000USD for retrofit, therefore i search for a new type or brand encoder.
Okay, well that clears up the confusion....since it's an LD (line driver)....you probably can't use the US Digital Encoders....unless you're willing to use a single-ended encoder....and the servo is a brushless servo??
It is AC brushless servo motor of Electro-Craft type H-4030. In generally, i could find encoder which have normal channel like A/B, Index, u, v, w, however the special signal ABS is not common.
what drive are you using to run these motors? Some of the drives that will work with this series don't need the "abs" track.
Hi Mr. Unterhaus;
Thank you for your e-mail. the driver is BRU200 of Electro-Craft, for my application, ABS track is must need. Do you have any information about ABS track?
Here is EPC's web page Rotary Encoders By Encoder Products Company
Thanks
Bill
contact ur local danaher controls dynapar encoder rep; he can get u a drop in exact replacement for this - it is a common enough encoder.
I missed also pointing out EPC (Encoder Products Corp) also has drop in replacements for this - Thanks for the reminder EPC Bill!
