machines and to
have continuous/
reliable operation

Functions
The AC motor drive can be
restarted/reset automatically up to 10
times after a fault occurs.
Functions
AC motor drive can use DC brake for
emergency stop when quick stop is
needed without brake resistor. When
used often, take motor cooling into
consideration.
Functions
The over-torque detection level can be
set. Once OC stall, OV stall and over-
torque occurs, the output frequency
will be adjusted automatically. It is
suitable for machines like fans and
pumps that require continuous
operation.
Functions
When user cannot provide
upper/lower limit, gain or bias from
external signal, it can be set
individually in AC motor drive.
Functions
The AC motor drive cannot run at
constant speed in the skip frequency
range. Three skip frequency ranges
can be set.
