STC-1000

Hi. Could the STC-1000 temperature controller that I use to monitor my VFD spindle temperatue be somehow connected to the 'door output' on the MASSO. If so how could this be done.
Regards JV

I think the problem might be with that is the STC-1000 I use is 230 vac input and output.

JV,

Explain how you are using the ST-1000?

It has two sets of NO contacts, at least one can be used to switch DC ground.

Regards.

I've not got this setup yet but this is what I was going to do when all the items arrive.

The STC-1000 as 240 volt ac input. I have two 240 volt warning lights, one red and one green. I would connect one to the heating relay and one to the cooling relay. this would I assume switch one of the lights on depending on the temperature setup.

JV,

Only install the Red warning lamp and use the other NO to signal MASSO. Set the temp trigger point the same for both circuits. The Red lamp is connected to the O/C NO contact and MASSO input is connected to the closed NO contact. That way when the trigger temp is reached Red lamp comes on and MASSO shuts down.

Now the best input to use is the coolant flow input as that stops movement and turns off VFD.

I installed a flow switch in the coolant return line, so if for some reason coolant stopped coming back to the reservoir, MASSO shuts down. I haven't had a job yet, that ran long enough to overheat the spindle or even for that matter to get warm enough to worry about.

Regards,

Arie.

Thanks for the information, I will do as you advise. The reason I want to do this is because the water cooling failed due to a blockage in the system. Thankfully I noticed before the spindle got to hot.
