Note: 1. The brake resistor capacity listed in the above table is based on the condition that the regenerative brake
duty is 10% (that is, in case braking lasts for 5 seconds, another 45 seconds must be provided for heat
dissipation). The brake resistor wattage can be reduced according to the user
’
s application (quantity of
heat) and the regenerative brake duty. But the resistance must be larger than the value list in the above
table (otherwise damage of the inverter thus be resulted in).
2. In case frequent start and stop operations are required, a larger regenerative brake duty should be set,
meanwhile, a larger brake resistor should be employed correspondingly. If there is any problem about
selection of brake resistors, please feel free to contact us.
