Frequency Reference Upper and Lower Limit
Settings (n30 and n31)
Set the upper and lower frequency reference limits in percent-
age based on the maximum frequency as 100%.

Note:
If n31 is set to a value less than the minimum output fre-
quency (FMIN) (n14), the Inverter will have no output
when a frequency reference less than the minimum out-
put frequency input is ON.
Rated Motor Current Setting (n32)
Set the rated motor current as the reference value for motor
overload detection (OL1).
Note:
1. Setting 0.0 disables the motor overload detection (OL1) func-
tion.
2. The rated motor current value is factory-set for each Inverter
according to the maximum applicable motor capacity.

Motor Protection Characteristic Selection (n33)
Set the motor overload detection (OL1) for the electronic thermal
characteristics of the motor.
Value
Description
0
Protection characteristics for general-purpose induction motors
1
Protection characteristics for Inverter-dedicated motors
2
No protection
Note:
When connecting multiple motors to one Inverter, set 2
(equivalent to n32 = 0.0). In addition, take overload pre-
vention measures by mounting a thermal relay in each
motor, for example.
Motor Protective Time Setting (n34)
Set the electronic thermal characteristics of the motor to be con-
nected in 1-minute increments.

Motor Protective Time
Setting
Note:
1. The default setting does not need any changes in normal op-
eration.
2. To set the parameter according to the characteristics of the
motor, confirm the thermal time constant with the motor
manufacturer and set the parameter with some margin. In
other words, set the value a little shorter than the thermal time
constant.
3. To detect motor overloading more quickly, reduce the set val-
ue, provided that it does not cause any application problems.
Cooling Fan Operation Function Selection (n35)
This parameter is used to operate the cooling fan of the Inverter
while the Inverter is turned on or only while the Inverter is in op-
eration.
Value
Description
0
The fan rotates only while the RUN command is input and for 1
minute after the Inverter stops operating.
The fan rotates while the Inverter is turned ON.
1
Note:
1. This parameter is available only if the Inverter incorporates a
cooling fan.
2. If the operation frequency of the Inverter is low, the life of the
fan can be prolonged by setting the parameter to 0.
