Delta Electronics Network Card VFDB Series User Manual

NFB  
5. The AC Motor Drive and braking  
unit will be electrified at the same time  
while turning on the NFB (No-fuse  
breaker). For the operation/stop  
method of the motor, please refer to the  
user manual of the AC Motor Drives  
VFD Series. The braking unit will  
detect the inner DC voltage of the AC  
motor drive when it stops the motor by  
deceleration. The extra regeneration  
will be dissipated away rapidly by the  
braking resistor in the form of heat. It  
can ensure the stable deceleration  
characteristic.

Thank you for choosing DELTA’s braking module. VFDB braking units are applied to absorb the motor regeneration energy when the  
three-phase induction motor stops by deceleration. With VFDB braking unit, the regeneration energy will be dissipated in dedicated  
braking resistors. To prevent mechanical or human injury, please refer to this instruction sheet before wiring. VFDB braking units are  
suitable for DELTAAC Motor Drives VFD Series 230V/460V/575V. VFDB braking units need to be used in conjunction with BR series  
braking resistors to provide the optimum braking characteristics. VFDB braking units (2015, 2022, 4030, 4045 and 5055) are approved  
by Underwriters Laboratories, Inc. (UL) and Canadian Underwriters Laboratories (cUL). The content of this instruction sheet may be  
revised without prior notice. Please consult our distributors or download the most updated version at

The +(P), -(N) terminals of the AC motor drive (VFD Series), connected to the braking unit (VFDB), must be confirmed

When the braking unit performs braking, the wires connected to +(P), -(N), B1 and B2 would generate a powerful  
electromagnetic field for a moment due to high current passing through. These wires should be wired separately from  
other low voltage control circuits lest they make interference or mis-operation.

1. Regulation of power voltage: the power source of the braking unit is DC voltage from +(P), -(N) terminals of the AC motor drive. It is  
very important to set the power voltage of the braking unit based on the input power of the AC motor drive before operation. The setting  
has a great influence on the potential of the operation voltage for the braking unit. Please refer to the table below.

Operation Explanation: 1. For safety consideration, install an overload relay between the braking unit and the braking resistor. In  
conjunction with the magnetic contactor (MC) prior to the drive, it can perform complete protection against abnormality.  
2. The purpose of installing the thermal overload relay is to protect the braking resistor from damage due to frequent braking, or due to  
braking unit keeping operating resulted from unusual high input voltage. Under such circumstance, just turn off the power to prevent  
damaging the braking resistor.

4. The alarm output terminals (RC, RA, RB) of the braking unit will be activated when the temperature of the heat sink exceeds 95oC. It  
means that the temperature of the installation environment may exceed 50oC, or the braking %ED may exceed 10%ED. With this kind  
of alarm, please install a fan to force air-cooling or reduce the environment temperature. If the condition not due to the temperature,  
the control circuit or the temperature sensor may have been damaged. At this time, please send the braking unit back to the  
manufacturer or agency for repair.
