Fanuc DC servo + 7i77

the drives are receiving a feedback signal based on encoder, these are the relevant settings:
OUTPUT_SCALE = 2857.0
OUTPUT_MIN_LIMIT = -2857.0
OUTPUT_MAX_LIMIT = 2857.0
FEEDBACK_SCALE = 3333.0
FEEDBACK_MIN_LIMIT = -3333.0
FEEDBACK_MAX_LIMIT = 3333.0
net x-output => hm2_5i25.0.7i77.0.1.analogout0
net x-vel-fb <= hm2_5i25.0.encoder.00.velocity => hm2_5i25.0.7i77.0.1.analogout1
velocity control is 6v/1000rpm the feedback should be 7v/1000rpm according to docs.

simple way to generate techo signal
mesa 5i20 + 7i33
setp hm2_5i20.0.pwmgen.04.output-type 1
setp hm2_5i20.0.pwmgen.04.scale 25
setp hm2_5i20.pwmgen.04.enable true
net x-vel-fb => hm2_5i20.0.pwmgen.04.value

Good Day,
Thanks for your reply.
The line ,
setp hm2_5i20.0.pwmgen.04.scale 25.
What reference did you use to arrive at the scale number 25?
Also did you increase the servo update rate?

i am using 24vdc small motor mount 100ppr encoder
with amc 12a8 servo amp.
working perfect with scale 25

Good day ,
Thanks for your reply,
I intend to use the pulse coder of the fanuc dc servo drives for tacho reference .
As I have only just started the refit on the Matsuura mill it will be some time before
the axis will be activated .
