ARTDrive V2 series - Instruction Manual
STARTUP / Drv & Mot config / BU olvd
The function protects braking resistor by monitoring current in the resistor according to
I2t characteristic. When the protection becomes active,
it is possible to generate an alarm condition. According to the different cases it is
possible to use the device internal IGBT (Internal-External).
