B&R 8AC122.60-6
Model Number: 8AC122.60-6
Product Introduction:
The B&R 8AC122.60-6 is a six-axis servo drive from the ACOPOS P3 product family. It integrates six independent servo channels in a single housing, enabling highly synchronized multi-axis motion control for complex machine kinematics. Each axis delivers the full performance of the ACOPOS P3 single-axis drive with SIL 3 / PL e safety.
