Note:
●Please only use the resistors and recommended values.
●The power and resistance recommended in above table is calculated by 100% of braking
torque and 10% of using frequency, under the circumstance that the load is satisfied and the
system is reliable, the resistor power and resistance can be increased or reduced properly; If
increasing of braking torque is needed or when using frequency is too high, power of braking
resistors and resistance should be changed properly, or consult our company.
●Take into consideration the safety of the environment when installing the braking resistors.
