Allowed inertia ratio application condition
A regenerative resistor that users connect to the outside according to
the load is called the external regenerative resistor. The rated power of
the regenerative resistor consumes the regenerative energy produced
from the load system. If the produced energy is small enough, users
can set up the external regenerative resistor and increase the rated
power of the regenerative resistor, so that the regenerative energy
produced from the load system can be consumed.
There are two ways to increase the allowed power of the regenerative
resistor. The first is connecting the internal regenerative resistor and
the external resistor in parallel, and the second is mounting an extra
external regenerative resistor after removing the internal regenerative
resistor.

ATTENTION
In case of increasing the rated power of regenerative resistor,
set the minimum resistor value according to capacity. (15
Ω
to
25
Ω
)
ATTENTION
The temperature of a resistance for the regenerative resistor
can rise over 200° C under the rated load condition. Because
without an extra cooling fan, the temperature of the
regenerative resistor can go up excessively, please use 20%
or less of the rated power of the regenerative resistor.
