Rated motor
current
Used to set the rated motor current for mo-
tor overload detection (OL1) based on the
rated motor current.
Note
Motor overload detection (OL1) is
disabled by setting the parameter to
0.0.
Note
The rated motor current is default to
the standard rated current of the
maximum applicable motor.

Motor protec-
tion characteris-
tics
Used to set the motor overload detection
(OL1) for the electronic thermal character-
istics of the motor.
0: Protection characteristics for general-
purpose induction motors
1: Protection characteristics for inverter-
dedicated motors
2: No protection
Note
If a single Inverter is connected to
more than one motor, set the param-
eter to 2 for no protection. The pa-
rameter is also disabled by setting
n32 for rated motor to 0.0.

Motor protec-
tive time setting
Used to set the electric thermal character-
istics of the motor to be connected in
1-minute increments.
Note
The default setting does not require
any changes in normal operation.
Note
To set the parameter according to the
characteristics of the motor, check
with the motor manufacturer the ther-
mal time constant and set the param-
eter with some margin. In other
words, set the value slightly shorter
than the thermal time constant.
Note
To detect motor overloading quicker,
reduce the set value, provided that it
does not cause any application prob-
lems.

Cooling fan op-
eration function
Used to operate the Cooling Fan of the In-
verter while the Inverter is turned on or
only while the Inverter is in operation.
0: Rotates only while RUN command is
input and for 1 minute after Inverter
stops operating
1: Rotates while Inverter is turned on
Note
This parameter is available only if the
Inverter incorporates a Cooling Fan.
Note
If the operation frequency of the In-
verter is low, the life of the fan can be
prolonged by setting the parameter
to 0.
