It is a little confusing the way you have drawn the circuit as you stated which would be AC but then you mention 70vdc ie DC. As John has indicated it is not good to switch DC with a relay.

That's more down to my diagram skills sorry! The drives take a.c. or d.c. but the Toroidal psu is rectified and is 70vdc so it looks as though it will be better to use the solenoid to power a contactor on the 240v side.
These drives dont have stall detection as far as I'm aware, maybe you're thinking of the Leadshine ones?
