Hello everybody!
We constructed our own SCARA robot for internal company purposes. As for mechanics, everything is ready. However, we still have not decided how are we going to control the unit.
The specifications are:
axis X - 200 W, 0.64 Nm servo with brake, absolute encoder
axis Y - 100 W, 0.32 Nm servo with brake, absolute encoder
Servo drives(it can be 2-axis one or two separate ones)
- Because it's a robot, there must be interpolation between the two axes. PLC or PC-based control over the two servo drives + some additional I/O.
I asked for quotes from different well-known brands such as Beckhoff and Mitsubishi, but the price for control compared to the expenses for building the mechanics is several times higher. The problem derives from the amount of redundant features of the equipment. For example, we were offered a Motion Controller capable of controlling up to 16 axes and at the same time we need just two and so on.
What we are looking for is a low-cost solution for controlling the unit. Because I do not have experience with some brands, that's why I am asking if anyone could suggest a brand manufacturer. It can be a manufacturer from anywhere in the world, well-known or not so popular.
Thank you in advance!
