Closed loop Step Servo Drive Driver 2HSS86H + 4.5N.M Motor + Encoder

[Boyan Silyavski]

They are nice but the price+customs+PSU= the price of a good second hand servo. And they are steppers with their good and bad. I was in doubt for 2 weeks and at the end i bought AC servo motors +drives. Which i suppose for the same money will bring the machine to another level.

What i mean is though they seem nice, it seems better to me to go with normal steppers or go to servos.

Yes I agree.!!. . . . .It will take it to Another level of head ache.!

Normal steppers don't even come close to these even with good drives and servo's offer nothing more other than speed and torque unless used with control that can close the loop correctly, infact they offer less if the loop isn't closed because they can only fault if a following error occurs not correct for positional loss.
If these drives/motors are sized correctly for the machine then they match servos for accurecy and absolutley blow them away for ease of use. No messing around with scopes and PID settings etc, just plug-in setup a few simple parameters and forget.

Servo's are great but they can also be a complete night mare and for DIY machine they can be more trouble than there worth with very little gain worth the trouble or cost.!!
