RB1, RB2, RB3: Braking Resistor
Note: The internal braking resistor causes a derating of the
continuous DC bus power. See page 4-12.
By connecting an external braking resistor the derating of the continuous
DC bus power can be prevented.
Note: When an external braking resistor is used, the drive has to be
informed of this fact by means of the DriveTop commissioning
software (call in DriveTop by menu item "Drive Functions ->
Drive controller")
An external braking resistor is available as an accessory.
Data for the internal braking resistor: see chapter 4.4 "Electrical Data"
