Functions
Electronic Thermal Function
•This function electronically protects the motor from overheating.
* To switch to the 2nd control, allocate 08 (SET) to the multi-function input and then turn it on.
• Causes an overload trip (E06) to protect the motor from overheating by setting according to the
motor rated current.
• Provides the most appropriate protection characteristics, taking into account the decline of the
motor cooling capability at a low speed.
• To set a value over the rated current of the motor, be careful of any temperature rise of the motor.
Electronic Thermal Level (Motor Protection Level)
(Example) 3G3MX-A2007
Rated current: 5.0 A
Setting range: 1.0 to 6.0 A
• The following figure shows the time limit characteristics with the electronic thermal level (b012) set
to 5.0 A.
Electronic Thermal Characteristics
•Frequency characteristics are multiplied by the b012/212 set value shown above.
• The lower the output frequency is, the lower the cooling capability of the standard motor's self-
cooling fan.
