Enter external Brake Resistor resistance in ohms.
For software protection of the connected brake resistor, enter the rated power and resistance of the resistor into the relevant parameters. The drive will then monitor the brake resistor to ensure that it does not operate outside of its designed limits. Where an external thermal protection device is fitted, and software protection is not required. Setting parameter P3-05 to zero will disable the software protection feature.
This parameter is used when a brake resistor thermal switch is wired back to a digital input set for External trip and tells the drive that the drive should trip on a brake resistor feedback fault (Ot-br) rather than an external trip.
This parameter defines the drive’s reaction when the Brake resistor overload function has been triggered (Ot-br)
Setting | Function | Reaction Details |
|---|---|---|
0 | Stop then Trip | Drive stops normally then trips |
1 | Trip Immediately | Immediate trip, apply motor brake |
2 | Warning Only | Warning only, no trip. |
