The NORDAC trio SK 300E is a combination of geared motor and highly functional frequency inverter which enables process-oriented, decentralized system configurations to be implemented very conveniently. Designed to ensure maximum ease of handling and operation the inverter is user-friendly in every respect. The inverter is provided with what can be described as an "electronic type plate" which the motor will read and permanently store with the effect that the inverter data are not lost to the motor even if the inverter is removed. As the inverter can be upgraded with a number of modules within the scope of a well thought-out concept, appropriate control components are available to establish the optimal configuration for any process to be controlled.

After many years of experience with motor-mounted frequency inverters, with the release of the SK 200E NORD has now introduced a new series of devices which enable a wide range of decentralised drive technology solutions. These robust, reliable and economic systems are suitable for extensive plant, e.g. conveyors, and were specially optimised for price-sensitive market segments. Similar to the SK 500E Panel Mount family, an application-oriented performance level is available which offers the same high quality functionality. Expected features of decentralised components such as robust design, integration of plug connectors, rapid replacement and decentralised modules for communication and I/O signals ensure reliable integration of distributed drive units at the field level.
Scope of supply - SK 200E:
1~ 115 V 0.25 – 0.75 kW
1~ 230 V 0.25 – 1.1 kW

The frequency inverter programs ECO-line, OPTI-line and PROFI-line consistently follow the same principle in the range of 0.2 to 90 kW as the Watt Drive modular drive systems.
These frequency inverters distinguish themselves through their excellent control features, compact size, ease of use and very good communication skills.
The differences in the three programs are mainly found in the control features and the related dynamics, starting torque and scope of application.
The L types are controlled by V/f characteristics and the V types are vector-controlled frequency inverters, while the P series is outstanding in its decentralized intelligence, for example for positioning.
With this program extension, Watt Drive is able to offer a complete range of modular drive control units and the most cost-effective drive solution for any requirement, from simple control and drive tasks to the control of top dynamic processes and positioning.

The KBDA Adjustable Frequency Drives are variable speed controls housed in a rugged NEMA-4X / IP-65 washdown and watertight die-cast aluminum enclosure. They are designed to operate 208 – 230 and 400/460 Volt 50 & 60 Hz 3-phase AC induction motors from subfractional thru 5 HP. The sine wave coded Pulse Width Modulated (PWM) output provides high motor efficiency and low noise. Adjustable Linear Acceleration and Deceleration make the drive suitable for soft-start applications.
Due to its user-friendly design, the KBDA is easy to install and operate. Setting the drive to specific applications is accomplished using the Multi-Function Keypad, which provides easy operation and programming of the drive. To facilitate programming, all similar functions are presented in common groups. For more advanced programming, PC based Drive-Link™ software is available.
The 4-Digit LED Display provides readout of drive operating parameters and programming functions and displays Output Frequency, Motor RPM, Output Current, Output Voltage, Bus Voltage, Function Codes and Values, Fault Codes, and Custom Units. In addition to operating the drive, the Multi-Function Keypad is used to change drive operating parameters, reprogram functions, and change the display output. The LEDs provide indication of the drive’s status and operating mode (Hz, PGM, LCL/REM, STOP, FWD, REV, OL, JOG/REM).
