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.
