Lathe Retrofit Handwheels | | I have a Hankook Protec 5N CNC centre lathe and the Fagor 800T system that ran it developed faults that were not, in my opinion, worth pursuing.
So we are converting it to a Kanalog/Kflop system with Mach3 on a PC.
We are making good progress with the conversion.
We have figured the wiring for the Yaskawa Servopacks and have the cross slide (X axis) and the carriage/saddle (Z axis) traveling okay, although the servos still need some tuning, but we are impatient to get on.
Setting up the limit switches and the homing switches is the next step and should be quite straightforward, now that we have traced all the wiring.
The Hankook Protec 5N is basically a standard centre lathe which has been transformed to CNC by the addition of servo drives for the longitudinal and cross feeds.
There is no longer any manual control of those feeds. It is all electronic with handwheel pulse generators/encoders taking the place of manual handwheels.
The question is how do we connect the two pulse generators/encoders for manually controlling feeds?
Do we connect to the Aux#0 and Aux#1 on the Kflop?
How do we "disable" the handwheels when Mach3 is in control and running a programme? (We don't want someone deciding that it may be nice to turn that interesting looking handle while the lathe is cutting a g-coded part.)
Any other suggestions on how to configure the machine would also be appreciated.
