Status
t1
-The AC drive waits for the RUN signal.
-----
Inhabit
t2
-The AC drive receives the Forward RUN command.
-----
RUN
-The IGBT becomes active.
-----
-DC Injection Braking 1/Pre-excitation is enabled if F6-06 > 0.
F6-05
(if F6-00 = 0, it is "DC Injection Braking 1";
if F6-00 = 2, it is "Pre-excitation")
F6-06
t3
-DC Injection Braking 1/Pre-excitation is disabled.
-----
RUN
-The startup frequency becomes active if F6-04 > 0.
F6-03
F6-04
t4

RUN
-The motor ramps down to zero frequency.
F0-18
-S-curve active
F6-08
F6-09
t7
-The frequency output command reaches the DC Injection Braking 2
frequency threshold.
F6-11
RUN (if F6-12 = 0)
Inhabit (if F6-12 > 0)
-The IGBT shall become inactive if DC Injection Braking 2 delay time
is not zero.
F6-12
-After the delay time set in F6-12, the IGBT becomes active again
-----
