Full-range automatic torque boost
●
Delivers outsanding starting torque (150%/3Hz) for its
class, for smooth machinery start-up.
Full range of protective functions
●
High-speed current-limiting function minimizes over-
current trips (above 250% of rated current) for enhanced
tripless operation (restart after momentary power loss,
stall prevention function, fault retry, etc.)
●
Inrush current suppression circuit buit-in.
Diverse operating methods and functions 
●
Multi-step speed operation (up to nine steps),
UP/DOWN operation and jog operation.
●
Full range of functions, including slip compensation,
overtorque detection and high-speed search.
Just wire it up and run!
●
Frequency volume setting knob located on the control
panel (operator) as a standard feature. Immediate
operation after you supply power. 
●
If remote operation is required, the optional operator
and cable can be mounted on your control panel.
Simple installation and wiring
●
The main circuit terminals are arranged in upper and
lower rows, so you can wire it up just like a contactor.
●
Main and control circuit terminals are screw-type, for
simple wiring and improved reliability.
●
One-touch mounting/detaching with DIN rail attach-
ments.
Wide range of input/output
●
Multi-function I/O terminals, 0-10V, 4-20mA or 0-20mA
inputs, as well as analog monitors are available.
●
Application freedom is increased since multi-function
inputs can be set to PNP or NPN.
●
One-touch mounting and/
or detaching. The life of the
cooling fan is extended by a
cooling fan ON/OFF control.

Even for a single given machine, the required motor torque will
vary with the load conditions. The full-range automatic torque
boost function automatically adjusts V (voltage) in V/f as
required. The VS mini J7 can adjust V for the required torque
during acceleration as well as during constant-speed operation.
The inverter calculates the required torque automatically.
Supprot for RS-232C and RS-485/422 (MEMOBUS protocol)
available as options.
Simple maintenance
