126Brake circuit commissioningFor Standard Application Program:• Switch off the overvoltage control of the drive (parameter 20.05).• Frame size R6: Check the setting of parameter 21.09. If stop by coasting isrequired, select OFF2 STOP.For the use of the brake resistor overload protection (parameters 27.02...27.05),consult an ABB representative.WARNING! If the drive is equipped with a brake chopper but the chopper is notenabled by parameter setting, the brake resistor must be disconnected because theprotection against resistor overheating is then not in use.WARNING! Parameter 95.07 LCU DC REF (V) must be set to the minimum value(default) with brake resistors. Otherwise energy from the supply network can flow tothe brake resistor causing overheating of the resistor and damage to the equipment.For settings of other application programs, see the appropriate firmware manual.Resistor braking
127External +24 V power supply for the RMIO boardsvia terminal X34What this chapter containsParameter settingsThis chapter describes how to connect an external +24 V power supply for the RMIOboards of the motor-side and line-side converters via terminal X34. For currentconsumption of the RMIO board, see chapter Motor control and I/O board (RMIO).Note: For the motor-side converter RMIO board, external power is easier to supplyvia terminal X23, see chapter Motor control and I/O board (RMIO).In Standard Application Program, set parameter 16.09 CTRL BOARD SUPPLY toEXTERNAL 24V if the RMIO board is powered from an external supply.External +24 V power supply for the RMIO boards via terminal X34
