As title says I can pick these up for the price of open loop steppers. A good buy?
I am just about ready to pull the trigger on these for the price. I have been reading about hybrid steppers vs servos (both closed loop) and it seems steppers can offer comparative performance, but would this be true of such drives as these? I'd have a little more faith going towards something such as leadshine brand.
Also, can you sort of use an 8.5nm closed loop servo in an application where you'd use a 12nm open loop servo? As you wouldn't need to worry about 'reserve torque'.
Any advice appreciated. Thank you.
