* Confirmed -part number ending in 3 for SIN/COS.

Just to throw a spanner in the works on sin/cos compatibility I have two gen4's that came direct from test vehicles used at Ashwoods Electric Motors in the UK that were fitted with heinzmann pms120's and Ashwoods own ELMO-S112, both motors are fitted with sin/cos encoders. The part number of the gen4's I have is 634A8320.

Doc, Methods says part number and you say serial number, is that what you ment to say?

Given that it is a hardware difference I wonder if it is not the hardware version number available from DVT that would be the most logical place to identify sin/cos compatibility. Anyway I intend to trace the sin/cos input pins on a compatible model and compare the circuitry compared to non compatible board to see if it is just unpopulated parts or totally different circuitry.
