Change of Heat Emission Characteristics of Electronic Thermal
When you set Electronic thermal Subtraction function enable, 1st-motor [bC112] to 01 (Enabled) when
the current is below the electronic thermal level, the temperature integration data can be reduced
according to the heat emission from the motor.
Precautions for Correct Use
• The electronic thermal of the inverter works independently even when the electronic thermal
subtraction time is made shorter.
• Appropriate setting should be made for the motor that you use.
• In case of [bC112]=00, resetting cannot be made in 10 seconds after occurrence of an error.
• [bC112]=00 to be set to be equivalent to 3G3RX-V1 Series.

Ex.2) Constant period mode ([bC112]=00)
In the constant period mode, a motor overload error [E005] and a trip occurs when either of the dupli-
cated counters reaches 100%. In the constant period mode, the thermal subtraction data are cleared
every 10 minutes (fixed).
