Allen-Bradley 1756-M16SE Sercos Servo Module

The 1756-M16SE supports integration of up to Sixteen (16) servo drives and supports SERCOS data rate of 4Mbps and 8Mbps. SERCOS cycle time varies depending on the data rate used specifically, 0.5 ms for 2 drives; 1 ms for 4 drives; and 2 ms for 8 drives @ 4 Mbps data rate and 0.5 ms for 4 drives; 1 ms for 8 drives and 2 ms for 16 drives @ 8Mbps data rate. This interface module supports drive control modes such as Position, Velocity and Torque.
