Dual MPG / hand wheels on retrofit lathe

Hi

Happy new year everybody :D

I am considering replacing the Anilam 4200T control on my current lathe. I have already done this for a knee mill so have a pretty good idea of what needs doing.

The one thing, I can't see in the instructions or documentation is how to configure the currently installed MPGs to enable manual control of the axes.

I saw the link pointing to some nice machines with this installed and the Centroid literature points to it being "standard", I just can't see the bit that say's how.

I'm hoping it's as simple as hooking up the MPGs to one of the spare encoder slots on the Allin1 and some software config.

Please can somebody point me in the right direction.

Thanks

Paul

Our controls support the use of Dual Handwheels, allowing you manual control of your axis while still keeping track of your position in the software. I have attached a simple wiring hook-up below. Do not think of the dual handwheel as an MPG since the MPG typically has an axis selector switch and a dual handwheel has designated encoder for a particular axis. You do not need to make any connections to the MPG connector on the MPU11/ALLIN1DC. The encoders will be connected directly to an encoder input on the MPU11/ALLIN1DC. There are parameters that will need to be set, P348 thru P356, in which you tell which encoder input the handwheels are connected to and characteristics of the handwheel encoder. The MPG logic in the PLC program will need to be as follows

; MPG 1 Enable
IF MPGLED THEN (SV_MPG_1_ENABLED), (SV_MPG_2_ENABLED)

; Select axis to move
IF true THEN SV_MPG_1_AXIS_SELECT = 2
IF true THEN SV_MPG_2_AXIS_SELECT = 1

You will also need to customize the PLC program if you have a joystick. The joystick would be used to jog an axis. The joystick is tied to certain inputs and the PLC program will look at that input and jog the particular axis when that input is set.

Perfect.

Thanks very much.
