Dynamic braking transistor modules in variable frequency drives use screw terminals for connecting external brake resistors to the DC bus for dissipating regenerative energy during rapid motor deceleration.
| Pin | Name | Function | Type |
|---|---|---|---|
| P | DC Positive | DC bus positive to braking IGBT | PWR |
| B | Brake | External brake resistor connection | PWR |
| N | DC Negative | DC bus negative | GND |
