Dynamic Breaking Resistor Setting Details
Set braking resistor configuration (%ED: Duty cycle). 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 has
expired. An example of braking resistor set up is as follows:
% =
_
_ + _ + _ + _
× 100%
[Example 1]
% =
_
_ + _1 + _ + _2
× 100%
