Hello,

To best of my knowledge, it is difficult (not possible) to adopt Fanuc motor to Siemens drive due to below limitations.

1.  Fanuc servo motor are designed to work with Fanuc servo drives & its infeed module works on 3 phase 220 V AC supply. Siemens 611 drive's infeed module work on 3 phase 400 V AC supply. Due to this difference in drives technology (DC bus voltage & inverter drive technology difference) , speed regulation of Fanuc motor with Siemens drives will not be much precise.

2. Fanuc servo motor has pulse coder Ai1000 which is not compatible with Siemens 611 drive.

Hope this helps.

 Thank you for your reply PISCEAN but i fear i havent explained myself fully, what im trying to do is replace the fanuc motor with a siemens motor with similar caracteristics.

OK. Sorry my understanding mistake.

So yes, you can replace Fanuc motor (refer attached motor data sheet) with Siemens equivalent motor, but need to modify mounting brackets & check the mounting feasibility. Also check what type of encoder does your system needs i.e. incremental or absolute & check Siemens infeed capacity.

Equivalent Siemens motor is 1FT6082-1AF71-1xG1 where x = A for sin/cos 1Vp incremental encoder or x=E for EnDAT absolute encoder 2048 S/R.

Tech spec of Siemens motor are -

Mo - 13 Nm, Nn - 3000 RPM, P - 3.2 Kw, In - 18 Amp, SH = 80 without brake since original Fanuc motor is without brake. Power cable 6FX8002-5CA02-1xx0 xx - length of cable.

Siemens LT module which you specified 6sn1123-1ab00-0ca2 is compatible for this motor but check its cooling as it is for external cooling.  

 You did not provide :

1--What kind of CNC or PLC controller you use for the machine 

2--What kind of Siemens control card you want to or already have to control the Siemens motor

Unless #1, and #2 information in detail, no good idea for you can be made

Im trying to figue out if its an incremental or absolute encoder

 

Fanuc motor number is A06B-0243-B101.  

Here 1 stands for alpha iI 1000 pulse encoder i.e. incremental encoder. Please refer attached sheet for more details.
