Internal DB TransistorProtection
Sets the protection function for the internal braking transistor.
1
(0, 1)
Disables braking transistor protection.
Use this setting, if enabling the braking transistor can cause an rF [Braking Resistor Fault] in these conditions:
With a regenerative converter, for example D1000.
With a regenerative unit, for example R1000.
When connecting braking resistor options to the drive, for example CDBR units.
Without an internal braking transistor.
Protects internal braking transistor when using a braking transistor or optional braking resistors.
These models have a built-in braking transistor:
2004 to 2138
4002 to 4168
