Testing Leadshine closed loop stepper system.

[Lee Roberts]

Thanks for taking the time to do this review/video Dean; I have a couple of questions for you...

1. What would make the fault signal handy for reporting back to Mach? my initial thoughts are you could use it to stop mach and also the spindle?, is there anything else it could be used for/to do? How would we use it to control a bunch of relays for things like the spindle, coolant and so on?

2. What/why would there be a massive mechanical advantage from this system when coupled to a lead screw?

Cheers,
Lee

The alarm signal can sink or source 20Ma current @ 24v so it could be used for either with the correct relay.

2. What/why would there be a massive mechanical advantage from this system when coupled to a lead screw?

There's no advantage from this particular system compared to standard system other than the digital drives being better at handling the current than analogue.

But when I said mechanical advantage I referring to the amplified forces of the rotational torque to linear force that the pitch of the ball-screw gives and therefore a mechanical advantage and the fact I wouldn't have been able to hold the Ball-nut like I did the pulley on the motor shaft if connected to ball-screw or any other linear motion translator with a ratio.!!
