* To switch to the 2nd/3rd control, allocate 08 (SET)/17 (SET3) to the desired multi-function input and then turn it on.
*1. Set a percentage relative to the electronic thermal multiplication value. When the value reaches 100%, an
overload trip (E05) occurs.
Electronic Thermal Level (Motor Protection Level)
(Example) 3G3RX-A2150 (0.4 to 55 kW)
Rated current: 64 A
Setting range: 12.8 A (20%) to 64.0 A (100%)
• The graph on the right shows the time limit
characteristics with the electronic thermal level
(b012) set to 64 A.
(Example) 3G3RX-A4750 (75 to 132 kW)
Rated current: 149 A
Setting range: 29.8 A (20%) to 149 A (100%)
• The graph on the right shows the time limit
characteristics with the electronic thermal level
(b012) set to 149 A.
Electronic Thermal Characteristics
• The frequency characteristics are integrated with the above b012/b212/b312 set values.
• A general-purpose motor requires reduced load (current) because the lower the output frequency
is, the lower the cooling capability of its self-cooling fan.
• The reduced torque characteristics are designed to fit the heat radiation of a general-purpose
motor.
