Not sure if Arduino is the way to go for long term reliability. They are great for hobby use but not really up to the task as a dedicated long term soloution. Just something to consider...
Au contraire, there is no reason to discount them on those grounds. They are extremely versatile, easy to program with lots of useful programs that can be modified in vast online libraries and they can be interfaced easily to mains voltages and high current with off the shelf modules.
I’m a big fan of raspberry pi/arduino stuff (I have a few myself), but I wouldn’t contemplate using one for something like this where it’s going in someone else’s house(s)Au contraire, there is no reason to discount them on those grounds.

The programming software is free. (This is a big deal, GX Developer for siemans costs in the region of £500)
I've spent the best part of the last 2 years building an embedded control system for a cable handling winch with a beaglebone black and a custom interface card. It's hard work rolling stuff from scratch, we could have saved a lot of effort going with a plc system...

The winch is a self contained package running from 230-1phase - it has embedded control electronics serving up a web control panel over wired ethernet. BBB is perfect for this application as it has 2x realtime cores in the silicon which handle the realtime motor control, and it also has a full web application stack (because it runs debian) so It can serve up the web control panel.What did you use to power the winch? What power supply do you require/expect?
We are using an AC servo (lichuan brand, think leadshine but cheaper), 750w so quite a bit smaller than yours... We run it in a mixture of step/direction and torque mode (0-10v)All sounds interesting, what's the motor and motor control? are you commutating the motor electronically? Does it operate in torque control or speed control?
I've done a few winches and tensioners, typically around 50 - 250 kW. We've just done the design work for a pair of 300 kW winches that will be synchronised.
Just to clarify a bit more, GX developer is not for Siemens kit.
The Logo software is 50 quid.
Okay, TIA Step7 Basic is 300 quid but that's a lot of software for the money.
