Universal Positioning Unit

A mechanism developed through the pursuit of outstanding functionality and performance. Superior movement achieved with zero-backlash technology In FA equipment, motion control using servo systems is a crucial element which greatly affects equipment performance. Naturally, equipment specifications and performance are designed assuming that the expected motion is attained, but if there are factors such as backlash, insufficient rigidity or control instability in the motion control section, then output motion will deviate from input control commands, and it will be difficult to attain the...
