How to put the 7i77 encoder in mode 1?

Hello everyone, I'm already on the client's machine, I'm trying to apply part of what worked in the lab test with 7i96s and
I'm trying to do the same client configuration on the 7i77 that was done in the lab on the 7i96s. But on the 7i96s I have to put:

setp hm2_7i96s.0.encoder.00.counter-mode 1

setp hm2_7i96s.0.encoder.00.filter 0

setp hm2_7i96s.0.encoder.00.scale -1

and will read the frequency applied to ENCA+ and ENCA- of THCAD2.

However, the 7i77 does not accept this configuration. What is the procedure to make the 7i77 change the encoder to mode 1?

 

Does not show hm2_7i96s.0.encoder.00.velocity

 

How to configure the 7i77 encoder to accept frequency?

 

Thank you, I did this and it worked, thank you very much
