Nord Drivesystems frequency inverter SK 180E series - Compact & Decentralized AC Vector Drives.

NORD, the drive technology specialist, has been developing and producing distributed control AC vector drives for more than 10 years. In 2009, we introduced the very popular SK 200E AC vector drive series, which was designed to mount directly in place of the motor terminal box to create a combined, fully integrated unit for use in the field. The SK 200E line is a distributed control companion to our successful SK 500E series cabinet mount drive. Together, our products offer a continuous range of performance along with optional features to simplify the drive selection process in order to serve a wide variety of applications. Although the original SK 200E series served the full range of drive applications from simple speed control in stand alone units to complex multi drive systems controlled via field bus networks or requiring position control, our customers have encouraged us to expand our product offering even further. NORD now offers a new product that fills the gaps between simple motor starters and complex AC drives. Many applications do not utilize the immense scope of functionality found in modern frequency inverters. This is why NORD has developed the SK 180E. This product focuses on the essential functionality that is necessary for pumps and conveyor technology. The SK180E is extremely energy efficient, cost effective and offers both significant savings as well as outstanding performance.

NORD CON.

NORD CON is the free operating software for controlling, programming and diagnosis of all NORD AC vector drives.
SK180E Interface Connection.
Connecting a SK180E to a PC/laptop is the most effective way to control your AC Vector drive. Connection is accomplished via the RS232 diagnostic interface on top of the AC Drive. The cable does not come standard with the unit but is available. We can provide a 10 foot sub D to RJ12 connector cable but needs to be ordered seperately. (Part Number 278 910 240).
Control.
The AC vector drive can be manually operated by means of a software window with all of the operating elements of a Controlbox. An enable signal with specification of setpoint values can be given. The parameter settings can be adjusted and read. Parameters (information and error messages) can be viewed. Users therefore have a supporting aid for each commissioning.
Programming. 
With a convenient overview, users can view and adjust each available parameter. By means of a print option complete parameter lists or lists of the changed values can be created. The finished data sets can be saved on the PC/laptop and archived for future use.
Diagnosis.
The NORD CON oscilloscope function is a simple but very useful instrument for the optimal adjustment of drive systems. By means of line graphs, all drive characteristics (current, torque, etc.) can be recorded and analysed. With these results, application-relevant settings can be fine-tuned to enable optimum operation. This is useful, e.g. for regulating the brake control or for lifting gear functions.

Nord Drivesystem vfd SK 180E series external customer units.

Variable Mounting.
For the distributed control SK 180E AC vector drives, optional technology units are available. These units may be mounted directly on the device or separately on the machine frame or plant component. Communication systems both with & without connection facilities for sensors, actuators and control modules are available for most current applications.
Tunneling of Parameter Data Via the System BUS.
The bus Technology units of the SK 180E provide economical and user-friendly configuration of the drive systems in the field. With the system bus, up to 4 AC vector drives and the bus technology unit can be linked via the system bus, which is integrated as standard. Therefore the connection to the host bus system is made at a single point. However, all data sets can be accessed by tunneling of the parameter data. Both the technology units and the data sets of each of the connected SK 180E devices can be accessed via the RS 232 interface.
