If the saw has a plug on the end of its cord then you can run a drop down with a single dedicated circuit receptacle. If it is meant to be hard wired {no male plug at the saw, just wires or a box on the saw for wires to run to} then you will need to have a fixed post {can be metal, can also just be a 4×4} at the location and a service disconnect box for code. Single phase 240, which is really just two 120 volt lines on different phases, could be either way depending on how the saw is configured from the factory. Three phase power will require a hard wire and a disconnect box at the machine.
You can add a plug to the saw, but if it didn’t come that way from the factory I wouldn’t recommend it. Will it work? Yes. Is it safe? Maybe. Is it code? No. Better to not take chances with power, especially 240 volt. If the saw has a plug and you run a drop down just be sure to use proper strain reliefs at the junction box in the ceiling and the receptacle box on the end.
