Dynamic Breaking Resistor Setting Details
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:
•
T_acc: Acceleration time to set frequency
•
T_steady: Constant speed operation time at set frequency
•
T_dec: Deceleration time to a frequency lower than constant speed
operation or the stop time from constant speed operation frequency
•
T_stop: Stop time until operation resumes
Do not set the braking resistor to exceed the resistor’s power rating. If overloaded; it can
overheat and cause a fire. When using a resistor with a heat sensor, the sensor output can be
used as an external trip signal for the inverter’s multi-function input.
