Is the spindle encoder differential?
If so, is the 7I77 set for differential inputs?
Hi MR.PCW
Yes, My spindle Encoder is Differential.

---- If so, is the 7I77 set for differential inputs?   
Hmmm, I not sure , How to recheck ?

Ahh  I just got you meaning set jumper.
Now I use Differential Done by default Board.

Asis,
 
 

Amp spindle Old model Sanyo Denki on brother TC-228 I not have document for check type of signal encoder.
But on board I see  26LS32  I think it's sent signal type differential.

My spindle type encoder differential signal , I can use function  "hm2_7i96s.0 encoder.05.quad-error-enable true"  right ?
Today I try.......
Change jumper on 7i77 Encoder 05 to quadrature position jump,

In hall I put use setp......... quad-error-enable true,
I test run step-up speed
M3 s200,
s500 ,
s1000
s2000
s3000
before s3000 all run good no show error .

When M3 s3000 it's show  "hm2_7i96s.0: Encoder 5 : quadrature count error"
any for me check next step ?

 
 

OK I would first verify the you have valid differential signals at the 7I77
You can do this by measuring the differential voltage with a voltmeter

You measure _between_ A and /A  and _between_ B and /B
and verify that you have > 2V absolute in each state.
(you need to wiggle the spindle around to get each state)
One state should be >+2V and the other < -2V
(absolute value always greater than 2V)

Hi Mr. PCW
I check done , result show below in picture
Asis,

 

Hi,
new update,
Yesterday I try install  EMI Filter on Servo Drive X,Y,Z 
result is same , after run gcode about 2 mins "M19 r0"  will wrong position.

 

I'd recommend using shielded cables and proper grounding.

Have any idea for orientation with 7i77 ?
I Ever use spindle motor mitsubishi Meldas it's have orientation mode internal .
When sent signal output to trick spindle amplifier orientation, it's will spin up (in second) and decrease speed down with lock position for orientation before toolchange .

I think if can reset index or position encoder before orient will work with 7i77 too , for clear all error signal before orient (I try a lot time if spindle run lower 3000 rpm will orient correct all time, but in real when working I use spindle 6500 rpm+ and will wrong position encoder maybe from noise)

Can for reset index or encoder position before M19 ?

Try this:
Machine powered and enabled
Spindle off
watch the spindle encoder count in hal show
make a line on the spindle to have a 0 reference point where the encoder shows 0
turn spindle by hand 10 times
see the encoder count, it is 10 times bigger?

Check the spindle encoder scaling, if you have a 1024 PPR encoder, probably scale should be 4096.
In this case after 10 turns you should see 40960
If not, there are two possibilities, scaling is wrong or encoder is faulty/miss wired/not counting properly/does not have quadrature outputs/voltage to low/ outputs not able to swing high enough to register/

There is no need for more that one of those for the whole machine if they are rated for more current than the machine can use.
Those are "line filters" so will not help with EMI created inside the machine, they do prevent interference going into or out of the machine through mains power lines.
For you case, ferrite beads or doughnuts on motor wires near the drives should help.
But as noted above by Aciera, shielded cables and proper grounding is essential.
