Name Description
Used to set the frequency
which starts DC injection
braking in units of Hz when
deceleration to stop is
selected.
When b2-01 is less than E1-
09, E1-09 is used to set the
starting frequency for the
DC injection braking.
In flux vector control, b2-01
is used to set the starting fre-
quency for the zero-speed
control.
Sets the DC injection brak-
ing current as a percentage
of the Inverter rated current.
The DC injection braking
current in flux control is
affected by any change to the
setting of E2-03.
Used to set the time to per-
form DC injection braking at
start in units of 1 second.
Used to stop coasting motor
and restart it. When the set
value is 0, DC injection
braking at start is not per-
formed.
Used to set the time to per-
form DC injection braking at
stop (zero-speed control in
flux vector control) in units
of 1 second.
Used to prevent coasting
after the Stop Command is
input. When the set value is
0.00, DC injection braking at
stop is not performed.
Sets the magnetic flux com-
pensation as a percentage of
the no-load current.
