Inverter with safe torque off input

13 September 2011

The E700 series inverter from Mitsubishi Electric is now available with a safe torque off input, eliminating the need for a redundant contactor in installations seeking compliance with EN954-1 Cat3 and IEC60204-1 Stop Category 0.

The new safe torque off version is denoted by the characters ‘SC’ after the ampere rating in the model number.

The new model is 6mm deeper than the existing version across the power range, and is compatible with connectivity and I/O option cards when utilising kits created for the safe torque off model. Standard features of the unit include soft pulse width modulation (PWM) switching, a self diagnostic mode, advanced flux vector control, and a flux optimisation mode designed to save even more energy than a fixed variable torque V/Hz curve.
