• For these motors, check the rated motor current and select an appropriate inverter based on the rat-
ed current of the inverter.
•
Do not set the base frequency to lower than the motor rated frequency. Doing so may cause over-
load or motor burnout.
• Do not select a motor incoming voltage higher than the motor rated voltage. Doing so may cause an
overload or motor burnout.

Motor Electronic Thermal Function
The motor electronic thermal function prevents the motor from overloading and burning. In addition,
M1 has a braking resistor electronic thermal function. (Refer to 6-12-2 Braking Resistor Electronic
Thermal Function
on page
6-67.)
• The motor electronic thermal function calculates the electronic thermal calculated value for motor
protection based on the output current of the inverter. The status of the electronic thermal function
can be checked by the monitor of electronic thermal overload protection for motor
(3003Hex-3CHex). When 100% is reached in the percentage display, motor overload (alarm codes:
17, 18) is detected.
• The motor electronic thermal function sets Motor Electronic Thermal Level (3004Hex-0CHex/
3009Hex-08Hex), Motor Electronic Thermal Characteristic Selection (3004Hex-0BHex/
3009Hex-07Hex) and Motor Electronic Thermal Time Constant (3004Hex-0DHex/3009Hex-09Hex).
• When Motor Electronic Thermal Overload Protection Data Retention (3008Hex-5AHex) is set to 1,
the electronic thermal cumulative value and thermal cumulative value of the overload early warning
are saved in the EEPROM when an insufficient voltage state has occurred, and, when the power is
next turned ON, EEPROM saved values are used as the defaults for cumulative values.
