Where wiring Tachogenerator on Argon Servo Drive

I am retrofit a Chiron FZ16 with Mesa 5i25 and 7i77 and now I have to replace the Siemens simoreg 6RB2025 ( It`s out of order now )
with the Argon Servo Drive .
The axis Motors are Siemens 1HU3058 with Encoder and Tachogenerator .

I have the Encoder wiried to the 7i77 card , but need I the Tachogenerator for Argon Servo Drive ?

It`s a lot of info in the Granite Devices wiki and eusurplus wiki but no about Tachogenerator .

Sorry for my english ....

Says that Tachogenerator is "planned"

The Argon drive has an internal velocity feedback loop using the encoders, so you may not need the tachogenerator.
I would suggest leaving the tachos mounted, they are doing no harm, but configure the machine to not use them initially.

You can use the encoder connected to the mesa AND to the argon
