Functions Related to Protection,
Warning, and Various Output Signals
This section describes the protective functions such as warning signals.
To enable the free-electronic thermal function, set the 1st/2nd Electronic Thermal Characteristics
Selection (b013/b213) to 02 (Free setting).
The free-electronic thermal function allows you to set the reduction factor for electronic thermal characteristic
according to your application.
As shown in the reduction factor graph below, set the three points that determine the electronic thermal
characteristics using the associated parameters.
When b016, b018, and b020 are set to the same rated current value, the reduction factor is x1.0.
However, the basic reduction factor shown below is effective independently of the free-electronic ther-
mal function settings.
The final reduction factor is equivalent to the reduction factor set for the free-electronic thermal function
multiplied by the basic reduction factor.
This final reduction factor is then applied to the current value set in the 1st/2nd Electronic Thermal
Level (b012/b212) to derive the reference value (100%) of basic characteristics for the electronic ther-
mal function.
