Re: Any experience or software for Control Techniques FNC4? Wha do I replace it with?
The Gecko and Leadshine drivers only accept feedback from encoders so unless you feed the encoder that is fitted to the ballscrew directly into the driver or fit them to the motor, then is will not work.
However, getting them tuned and working well is another matter and personally if i were to change them i would put ~AC servo motors on it.
Also Single ended output form an encoder is not ideal and differential is much better.

These Encoders are Incremental and Differential but it would be no big deal to use a line driver to convert single ended to Differential if needed.
The Encoders would have to go to the Drives in any case because the IP-S or IP-M don't have encoder inputs. Only the IP-A takes Encoder feedback.
Chaz the Tacho's are not used if using Step & Dir drives as they run in position mode and only needed for Analog drives for velocity feedback when used in Velocity mode.

Jazz, I believe they are standard DC motors. They are not steppers.

It seems, you can use the encoders (eventually you must add a small resistor from Encoder to the input clamps of the Driver), but you must enter the right amount in the configuration pages. With the 2000PPR you can make 8000 steps per turn of your spindle. If you have a 4mm spindle, then you can have a maximal resolution of 0,0005mm.

Yes I know I've got all the Details of the machine. They are actually Swiss made Maxon DC Motors. I refered to Step & Dir signals that New Modern DC drives would use not Steppers drives.

Ah OK, that explains it then.
