Providing the same external dimensions and supporting the existing positioning command systems, input/output signals and internal channels, the new EDD supersedes the EDC as NSK’s first choice for standard configurations.

Among the key benefits of the EDD drive unit is even higher levels of safety. For instance, an updated connector design prevents incorrect insertion. A further safety enhancement is the introduction of a locking mechanism to help avert accidental detachment (unplugging) from the EDD drive, which accordingly features a new cable set.

Ease of use also gets a boost. By way of example, the single-phase power supply is now a unified 100-240 VAC unit (previously two models: 200-230 and 100-115 VAC). Furthermore, analogue input has become standard on the EDD drive unit to control speed and torque, while the maximum input frequency of the pulse train position increases to 2 MHz (previously 1 MHz), enabling even quicker positioning during high-speed operation compared with the EDC 100 VAC model.

Another usability enhancement sees the introduction of a USB connector to link with ‘EDD Megaterm’ software via a computer. The new EDD software supports high-speed oscilloscopes and their FFT (Fast Fourier Transform) functions. Moreover, the software makes it easier to set, edit and tune the EDD.
