Note If a single Inverter is con-
nected to more than one
motor, set the parameter to 2

eter is also disabled by set-
ting n036 for rated motor to

Used to set the electric thermal
characteristics of the motor to be
connected in 1-minute increments.
Note The default setting does not
require any changes in nor-
mal operation.
Note To set the parameter accord-
ing to the characteristics of
the motor, check with the
motor manufacturer the ther-
mal time constant and set
the parameter with some
margin. In other words, set
the value slightly shorter
than the thermal time con-
stant.
Note To detect motor overloading
quicker, reduce the set
value, provided that it does
not cause any application
problems.
