SWI Trak 1745P - Allin1DC Retrofit

Limit Switches:

This machine doesn't have them. We have been discussing adding them this morning (location, type, etc.)

What would you recommend? Am I correct in assuming that they are needed for homing on this conversion, unlike the mill we just completed? (Leadshine EL7).

I'm using proximity sensors like these for the gearbox position inputs:

That is what we are looking at using for the axis limits as well, if possible, in order to simplify the parts list, but I'm open to suggestions.

In looking at the spindle brake, are there strong reasons to get the optional braking resistor for the Freq drive, rather than re-using the mechanical brake that this machine is currently fitted with?

We are using an automation direct GS30.

I was planning to just re-use the braking circuit, including the timer, but maybe this is unnecessary with the new controller?

What would you advise?

I would reuse the electromagnetic brake built into the machine. A braking resistor in a vfd will slow you down but will not stop the motor.

Just my $.02

Ok, will the Allin1DC eliminate the need for the brake timer? Should I just get rid of that?
