Note:
Please select the power and the resistance value recommended by our
company.
The power and the resistance value that recommended above can be
calculated by 100% braking torque and 10% frequency of utilization.
The power and the resistance value can be appropriately reduced as
long as it meets the load demand and the system is reliable: The power
and the resistance value of the braking resistor should be appropriately
changed if the braking torque and frequency of utilization need to be
increased,or users can contact the company.
When installing a braking resistor
，
please consider the safety and the
inflammability of the surrounding environment.
The frequency of use of Braking:
UD= t1/ t2*100%
tl
：
the braking time in a working period;
t2
：
a working period;
If the braking efficiency is double, the power of the corresponding braking unit
and braking resistor also need to be double.
