cn1 sur velocity amplifier  a06-6045-h001,h002 pin out, voltage et comment activer les pin nécessaire en low , high ou sinking ou sourced
le pin out du FUJI ELECTRIC DSR COMPACT FSD-11 SN-Z for cn1 and cn2    +10v + foward and reverse

et la derniere question changer mon index pulse coder pour un encoder abs je devrait acheter une carte ssi pour interfacer avec mon encoder,  c pour une tourrette hydraulique  6 position avec un index pour le milieu de la course, ou l'autre option envisager est de prendre une carte arduino  pour convertir mon signal en output et réserver 7 input pour le positionnement de tourret, ou d'utiliser une table binaire pour sauver des input, j'aimerai de quoi de simple et d'économique vos recommandation svp j'ai voulu mettre des swith individuellle mais manque un peut de place, si je trouve pas mes information je me tournerait surment sur des drive et moteur dyn4 de DMM , surment avec une carte 7i76+ 7i92 + usb mpg,  je me demande si je vais en closed loop sur la mesa ou directement dans la drive, j'avais pensé a acorn mais j'aime bien l'idée  de mesa et de linux, mais ethercat  sa seras quand les drive seront moins dispendieuse, 
Merci a tous réponder en anglais en francais ou tout autre, thanks a lot and good day

The (*) usually means the common or complement or active low.

that's is what i found on drive 6047 but not sure its the same of 6045-h001?!

The CN1 connectors have these signals:

PRDY: CNC sends contact closure between CN1 pin 1 and CN1 pin 14
ENBL: CNC sends contact closure between CN1 pin 2 and CN1 pin 15
OVL: Servo sends contact closure betwen CN1 pin 3 and CN1 pin 16
VRDY: Servo sends contact closure between CN1 pin 4 and CN1 pin 17
Tach signal - analog input to servo between CN1 pin 6 and CN1 pin 19
VCMD signal - analog input to servo between CN1 pin 7 and CN1 pin 20

All other pins are unused.

The contact closure OVL from the servo to the CNC is from the motor overload sensor (the current sensor on the motor armature current that has the little red reset button).

The contact closure VRDY is from a small set of contacts on the side of the big MCC contactor.
Pins 19 and 20 are both tied to ground on the board, so the the tach signal on pin 6 and the Velocity command signal on pin 7 are both measured relative to the same ground reference. The check pins CH3 and CH4 are both grounded also, so you should see continuity between pins 19 & 20 and CH3 and CH4

Pins 14 and 15 are both tied to +24vdc on the board, so when the relay contacts on the CNC close for the signals PRDY and ENBL, the +24v from the servo board is put on pins 1 and 2, respectively. This +24v is from the little power supply on the X axis servo board, which also appears at CH15. The Z servo board usually does no have a power supply, since it shares power with the X board through a ribbon cable.

  thats it dsr fsd all tag identification it's there  inside the mr20 connectornow OS. its 0v but osg??  and i think dsr it s  -10v to 10v   or 0 to 10 v  , i will press m4 and m3 this week can to confirm that, i will play with wiring  too    thankx Tomlol i will check for changing the resolution ..Pat 

fot velocity amplifier These Fanuc drives do accept analog inputs. The small motors (00,0,5) use a 3.5v per 1000 RPM command signal, and the larger motors (10,20,30) use a 7v per 1000 rpm signal. The inputs can go to 10v without losing linearity. The gain is adjustable on the board, so you could use a +/- 10v analog signal if you need to.

The biggest problem with trying to use the Fanuc drives in a retrofit is that the tach signals are usually generated by the CNC using the pulse coder feedback. The pulses are put through a "frequency to velocity" converter so that an analog tach signal is generated for the servo drives, and the need for a real tach generator is eliminated. The tach signals are always 6v per 1000 rpm of the motor. There are some Fanuc motors out there that have tachs in them, and the pulse coders are separately coupled to the ballscrews. Most of the time, however, there are no tachs in the motors and the pulse coder is mounted inside the back cover of the motor. This works fine if your motor is directly coupled to the ballscrew. A few machines have motors with tachs driving the ballscrew with a Gilmer belt, and the pulse coder is directly coupled to the screw.

If you have motors with tachs and separate pulse coders, you should be able to use the servos, motors and pulse coders in almost any kind of retrofit. If the pulse coders are inside the motors, you would need to make some kind of F/V circuit to generate the tach signals, or mount a separate tach generator that's driven at the same speed as the motor.

The CN1 connectors on the Fanuc servo boards have an analog VCMD (velocity command) signal and also a TSA/TSB signal for the tach input. There are also some relay closure signals from the CNC that pull in the servo contactor (PRDY) and enable the firing circuit (ENBL), and there is a contact closure on the servo to confirm that the drive is ready (VRDY).

The sequence is pretty simple. The CNC boots up and closes a contact to send the PRDY (Power ready) signal to the servo. The servo pulls in the big MCC contactor and sends back a contact closure signal to confirm that the velocity unit is ready (VRDY), then the CNC closes the enable signal (ENBL) and you're off and running. The VCMD velocity command analog signal should be clamped to 0v until the servo is enabled, and your tach signal should be live before the ENBL signal is sent. A tach that's missing or backwards polarity will cause a motor to runaway (fast!). A missing phase will cause the motor to run rough and have little power.

Maybe one of the other forum members has cooked up a little F/V converter for generating tach signals for these servos. How about it guys?

what a pine do you talk, cn2 it's tacho with temperature sensor,, i have 7192/ 7i77d (siniking), the spindle drive have 0 to +10v need pin to reverse i will dig this wk-end For Cn-1 pin 18 its os, i think it's a word, i will check my electrical diagram but not all info in there. and the manual i pick it with a lathe it s 6t model b not a, the turret it's hydraulic ,its is old pulse coder 6 position with index in midle stoke of each position , i will check for new, abz (360,600 or other , need to index(homing) want wake it up and generate a pulse in middle on tool position and split 360 in 6 for 60 degree to check parity (slow down the turret and whent hit the synthetique pulse, stop in place and clamp) do you have suggest for adapteur brand 6mm encoder shaft to 10mm on the machine ?! tkx Tom

i think 400 it's 0v

437,512 and 546 it's for run , forward and reverse , 3 magentic contactor (run give the power, and after f or r its activing not 2 in same time ,

i will confirm that
