M-EDC-PS3090AB502-A - EDC Driver Unit - NSK

The NSK Megatorque Motor’s reliability effectively demonstrates NSK’s full manufacturing and design capabilities.
The Megatorque Motor boosts productivity and achieves high performance in full compliance with the latest safety standards.

With advanced features, including high torque, high resolution, maximum rotational speed of 10 [s–1] (PS Series), high rigidity and compactness, the Megatorque Motor complies with CE mark (PS/PN Series), UL standards (PS/ PN Series), and the EU RoHS directive. These innovative direct-drive motors are extremely accurate, light-weight, and boost the productivity of various devices.

The Megatorque Motor’s absolute position sensor is capable of a high resolution of 2 621 440 [count/revolution] and repeatability of ±2 [arc-sec]. It requires no homing operations and facilitates the development of highly accurate devices.

A new servo algorithm shortens settling time to less than one- fth of conventional NSK motors. Shortened positioning time boosts the productivity of various devices.

The optimal magnetic eld design gives it more than twice as much force density as conventional NSK motors. A maximum of 50% increase in motor torque increases productivity during high acceleration/deceleration drives.

NSK’s advanced design technology has produced two unique motor series: the low pro le PN Series (height of PN2: 35 [mm]) and the light and compact PS Series (outer diameter of PS1: φ100 [mm]).

The product lineup includes the PN Series with brake and the Z Series with High Environmental Resistance (dust-tight, watertight).

Interchangeable Motors and Driver Units can be randomly matched. Increased positioning accuracy of 90 [arc-sec] and interchangeability improve ease of use.

The EDC Driver Unit’s positioning controller function is provided as a standard feature. In addition, an electronic gear function is built in for setting the pulse train position command. The EDC Megaterm software is used to collect, edit, and monitor data.

Compliance with international safety standards (UL Standards, CE mark) assures worldwide applicability (PS/PN Series). The Megatorque Motor is environment friendly and complies with the EU RoHS Directive.

M-EDC-PS3090AB502 :

• Adopts new servo algorithm (achieves settling time of 1 [ms])
The EDC Driver Unit adopts an original disturbance observer and preview-based feed-forward control, which signi cantly reduces the positioning time, especially the settling time (approaching time).
• Positioning controller function
Positioning operation can be controlled without complicated communication or upper controller.
• Compact Driver Unit
Combined with special electric components and advanced integration technology, the Driver Unit body is 65% smaller than conventional NSK units.
• Variety of control I/Os
Control input/output required for positioning is available, including an encoder output, servo control and program control; no additional sensor is required to monitor the status.
