Dynamic Breaking Resistor Setting Details
Code Description
PRT-66 DB
Warn %ED
Set the braking resistor configuration (%ED: Enable Duty). The braking
resistor configuration sets the rate at which the braking resistor operates
for one operation cycle. The maximum time for continuous braking is 15
sec and the braking resistor signal is not output from the inverter after the
15 sec period elapses. An example of braking resistor set up is as follows:
[Example 1]
%𝐸𝐷 =
𝑇_𝑑𝑒𝑐
𝑇_𝑎𝑐𝑐 + 𝑇_𝑠𝑡𝑒𝑎𝑑𝑦 + 𝑇_𝑑𝑒𝑐 + 𝑇_𝑠𝑡𝑜𝑝
× 100%
[Example 2]
%𝐸𝐷 =
𝑇_𝑑𝑒𝑐
𝑇_𝑑𝑒𝑐 + 𝑇_𝑠𝑡𝑒𝑎𝑑𝑦1 + 𝑇_𝑎𝑐𝑐 + 𝑇_𝑠𝑡𝑒𝑎𝑑𝑦2
× 100%
