AKD2G Servo Drive

AKD2G features include dual-axis, expandable I/O (without increasing the size), removable memory, dual-channel STO, and the first drive-resident graphic display in the industry. The AKD2G is optimized for single-connector AKM2G and AKM (with or without brake) reducing wiring with single hybrid cable technology. AKD2G also offers an option for secondary feedback to support legacy feedbacks.
