Safe torque off model

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 Cat.3 and IEC60204-1 Stop Category 0. The 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 both connectivity and I/O option cards when using kits created for the safe torque off model. Although compact, the E700 is highly versatile and is suitable for both OEMs and end users who have constant or variable torque loads.

Motor-friendly soft PWM (pulse width modulation) switching, selfdiagnostic mode, advanced flux vector control, and a flux optimisation mode that, the company says, is designed to save even more energy than a fixed variable torque V/Hz curve are standard features.
