I forget what version of the Fanuc Controllers this applies to, but
there were some controllers that had a compact flash slot on the front.
The compact flash slot was used to load and read out the PLC program
logic and the other controller settings. The programming was done
offline on a laptop and the logic was written to the compact flash
module, then the module was used to load the controllers memory.
It was awkward.
You needed a $$ license to run the software.
This was years ago, but the Fanuc tech guy was charging way over $200/hr
to make changes.

Can you say what servo amps you have? The oldest Fanuc had standard
analog velocity servos, but instead of a DC tachometer, they
synthesized the tach signal from the encoder. Some machines had the
tach in the motor but didn't use it, so it could be set up to use the
existing tach. This applies to the brush motor (yellow cap) series.
Later units had brushless motors (red cap) and the servo amps were
supplied 6 separate PWM signals, one for each transistor. That uses
up a lot of PWM outputs.
