11.8 Braking Resistors (DB) and Braking Units
11-18
[ 3 ] Overview of braking unit
To improve the braking ability of inverters with the following capacity, use in combination with a braking
resistor.
Inverter capacity
200V series: FRN0346G2S-2G or higher
400V series: FRN0216G2□-4G or higher
200V series FRN0288G2S-2G or lower/400V series FRN0180G2□-4G or lower inverters are equipped with a built-
in brake transistor, and therefore do not need a braking unit.
