B2-04 Braking point 330.0V ～ 800.0V
360.0V
690.0V
☆
< 1> is the value of the 380V class inverter, and the value is 360.0V at the 200V class;
This value is the voltage point at which the braking resistor turns on. When there is a braking
resistor and the bus voltage is greater than B2-04, the inverter will release excess braking
energy through the braking resistor to prevent overvoltage of the inverter.

350.0V
☆
< 1> is the value of 380V class inverter, and the value is 200.0V in 200V class;
This value is the judgment point of the inverter undervoltage fault. When the inverter bus vol-
tage is lower than this value and it is running, it will output Err12 undervoltage fault. At the
same time, the reset mode of the undervoltage fault can be selected through P9-17.

B2-06 Random PWM depth setting 0 ～ 6 0
☆
This function is only valid for VF. Random PWM can soften the monotonous harsh motor so-
und and reduce external electromagnetic interference. If the random PWM depth is different,
the effect will not work, and 0 means invalid.
