Good day all.
It has been a while since I last posted here, and now I have come for some advice.
I recently acquired a Deckel FP3NC in mechanically excellent condition. Had some electronic issues like non-functional screen etc., but mostly it is sorted now. I'm unfortunately forced to run this off a RPC. The one issue I can see is on spindle startup. I'm sure (after reading previous posts) that the in-rush current is to high, which causes a voltage drop and the control resets.
I have this idea to fit a "soft starter" between the motor contactor and the motor. Just to clarify, not a VFD, but a rather a device on which you can adjust the "ramp up" time of a 3 phase motor. It works by chopping the sine wave with thyristors and gradually switches to full supply voltage over the specified time.
I would like to know if anyone has tried this? And also if there is any motor feedback, like current, speed, etc. being fed back into the control that might conflict with my idea?
See attached the youtube video on the device explanation.
Thanks for lending me your ears (or eyes for reading)!
