Point!
If the inverter drives the light
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.
The inverter processes 5 tasks at
the same time, which allows you
to realize 5 times faster EzSQ
processing in maximum.
WOP, the optional LCD
Operator, provides several user
friendliness;
− Multi data monitoring
− Parameter configuration as
monitoring data
− Parameter / Program copy
− Multi-language display
Approx. 6 times faster
communication in comparison
with the former model are
supported. In addition, some
communication commands are
newly supported.
You can initialize easily only by
setting the parameter and no
special procedure is required
Protection function expands to
not only input side but output
side, which provides more
reliable protection against the
phase loss.
