AKD®2G Servo Drives

AKD®2G features include dual-axis, expandable I/O (without increasing the size), removable memory, dual-channel STO, and the first drive-resident, colour graphic display in the industry. The AKD®2G is optimised for single-connector AKM2G and AKM motors (with or without a brake) reducing wiring with single hybrid cable technology. AKD®2G also offers an option for secondary feedback to support legacy feedback options.
