‘Intelligent’ inverter can handle drive-related tasks without an external controller

Nord Drivesystems has extended its SK 500E range of control cabinet inverters to include the IEC 61131 compliant SK 540E.

The new 'intelligent' inverter is designed to support a wider range of drives than its sister models and is said to be able to control synchronous motors without an external PLC. The module integrates a high performance microprocessor for high speed cutting processes in turning and milling, and provides the safety function Safe Torque Off. A sensorless current vector control and brake chopper have been integrated for regenerative operation.
