NSK New Driver Unit for Megatorque Motor? PS/PN Series
12 Dec,2019
NSK Ltd. (NSK; Headquarters: Tokyo, Japan; President & CEO: Toshihiro Uchiyama) has released a refreshed driver unit for Megatorque Motor PS/PN Series. The new driver will be exhibited at NSK's booth at International Robot Exhibition 2019 from December 18-21.
Previous model:
EDC Driver
New model:
EDD Driver
The EDD model maintains broad interchangeability and functional compatibility with EDC driver units. The popular EDC model, first released in 2007, was rapidly adopted by semiconductor and electronics manufacturers for its highly reliable and accurate performance. The EDD model is an update refreshing the internal electronics to secure supply chain stability of essential components and improve safety and ease of use.
Model Selection Moving Forward
The EDD model driver unit succeeds the EDC model for standard configurations.
EDC Driver
Available to support CC-Link and MECHATROLINK-Ⅲ functionality.
EDD Driver
(New model)
For all other configurations.
*We recommend the EDD model unless using CC-Link or MECHATROLINK-Ⅲ.
Overview
1. Interchangeability with EDC Model
Same external dimensions (same attachment dimensions).
Supports current positioning command systems and input/output signals.
2. Improved Safety
Updated connector design to prevent improper insertion. Also includes a locking mechanism to help prevent accidental detachment (unplugging). EDD models accordingly use a new cable set.
3. Improved Usability
Updated and unified power supply to a single phase 100-240 [VAC] unit. (Previously was two models: single phase 200-230 [VAC] and 100-115 [VAC].)
Analog control input is now standard on EDD model. Can control speed and torque.
Pulse train position command maximum input frequency increased to 2 MHz (previously 1 MHz) enabling even quicker high-accuracy positioning during high speed operation.
Added USB connector to link with a computer installed with “EDD Megaterm” software. The new EDD software supports high speed oscilloscopes and FFT, and has been updated overall to make it easier to control, edit, and tune settings. Note: The English version of EDD Megaterm is expected to launch in April 2020.
