Features:
- Indicates a nominal motor power rating of 4.0 kW (5.3 Horsepower)
- Specifies a 3-phase AC input voltage range of 380V to 480V, running on a 47 to 63 Hz line frequency
- It features an integrated Class A power input emitter filter to mitigate high-frequency electromagnetic interference (EMI)
The NORDAC SK 700E frequency inverter is designed for the power range between 1.5 kW and 160 kW. The system works with sensorless current vector regulation (ISD). The typical overload capacity is 150% for 60 s or 200% for 3.5 s. As standard, the devices are equipped with a brake chopper and line filter (for limit curve A according to EN 55011, up to 22 kW). The combination of a powerful control module and comprehensive protection and monitoring systems for the controller and the motor ensure great system reliability.
The open, modular concept of the NORDAC series enables the use of SK 700E inverters in a wide range of applications. Via internal modules for I/O and field bus connection, and by means of external plug-in technology units, the units can be individually configured and extended according to requirements. In combination with an incremental and/or absolute encoder, high-precision process applications can also be achieved. If necessary, the inverter can even handle positioning tasks, which can be performed without PLC control.
The SK700E-401-340-A NORD AC Frequency Converter Drive may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

In order to implement simple but precise positioning control with a frequency inverter, the SK 700E provides the optional extension POSICON. Due to the simple principle of this positioning, the corresponding applications can be implemented by anyone. With this, there is no need for servosolutions if the dynamics and precision of the asynchronous motor are sufficient. A relative (e.g. pulse operation, rotating platform) or absolute regulation of position (finite axis, linear movement axes) can be carried out. The module contains one input each for an incremental encoder (TTL) and an absolute encoder (SSI interface). The switching of movement and positioning signals is carried out optionally by means of binary (terminals) via the bus system.
As well as the display of all information parameters, the oscilloscope function can be a useful diagnosis instrument. Up to 4 selectable values (e.g. current, frequency) can be recorded as a line graph over a
period of up to 2 hours. Automatic scaling can be selected and enables simple handling for rapid results. With this, the various applications, e.g. brake drives can be quickly and simply optimised by anyone.
