Guide to brake assembly

The following table is the guidance data, where a user can select the resistance and the power according to the actual conditions (The resistance must not be less than the recommended value in the table, but the power can be increased.).

The brake resistor is selected according to the power generated by the motor in the actual applications, related to the system inertia, the deceleration time, the energy of potential load, depending on the customer requirements.

The larger system inertia is, the shorter deceleration time is needed; the more frequent brake is applied, the larger power of the brake resistor is selected and the resistance is smaller.

Selection of resistance

During the brake, the recycling energy from the motor is almost consumed on the brake resistor.
According to the formula: U*U/ P= Pb
■ U in the formula – – – brake voltage
(depending on the system, generally take 700V for 380VAC system)
■ pb— brake power

Power selection for brake resistor

In theory, the power for the brake resistor is consistent with the brake power. However, derating is considered as 70%.
According to the formula: 0.7*Pr=Pb*D
■ Pr– resistance power
■ D— brake frequency (The recycling process shares the ratio of the whole work.)
Elevator — -20%~30%
unwind and wind —20%~30%
centrifuge —50%~60%
Sudden brake load –5%
generally take 10%

  1. The brake assemblies are used to consume some potential or energy fed from the load with larger inertia to the frequency inverter, which can avoid inverter trip owing to high voltage. They can be applied for the load with larger inertia and frequent brake or quick parking.

  2. The brake assemblies belong to peripherals. The brake unit is built in the inverter (0.75-18.5). If the brake function over 22kW is required, please order the inverter with the brake.
  3. Don’t directly connect the discharge resistor to the P or N terminal. If the inverter terminal is P or N, the discharge block must be additionally installed. If the brake assembly over 93KW is connected to the P or N terminal, please remind us before ordering.
