load application (e.g. fan pump
application), you can choose
the one size smaller capacity
inverter than the motor capacity,
which allows you to reduce the
total cost of your system.

improved user
friendliness.
The inverter processes 5 tasks at
the same time, which allows you
to realize 5 times faster EzSQ
processing in maximum.

(initialization selection),
press some keys.
In addition to the
conventional method,
executing initialization
by a parameter is
possible.
(Select b084 and
