siemens 6SC6101 question

good morning, I have the following question. I have 4 Siemens 1FT5 servomotors and servo controller 6SC6101 controller 4 axis, but I notice that in the original machine configuration of the encoder cable go directly to the servo controller at siemens 6SC6101 and not to numerical control, in this case I can not use my 7i77 to control servomotors such?

Any idea if it is possible to adjust my servocontroller with mesanet 7i77?


thanks.

Looks like the motors do not have normal encoders but rather some kind absolute encoder just used for commutation. My guess is that these were used with external encoders for controller feedback so you would probably have to add encoders for feedback.

Peter, thanks for your response. has the same encoder to use with my first machine which you helped me a lot,

Has this encoder in servomotors:

you think you only connect the encoder to the 7i77 and done?

Not compatible with 7i77?

I appreciate your attention.

That encoder should be compatible but the drive manual I could find used a different encoder type that only goes to the drive. Do you have the exact drive manual?

if I have manual servo. how to define if it is compatible with my 7i77?

is that the question is rather silly but I really do not know how to define if it is possible to retrofit this servodrives

thanks.

The 6SC6101 I looked up is a analog velocity mode servo which is compatible with the 7I77 but would need an additional encoder

thanks.. Peter. solved.
