DC Injection Braking: b2
User constants for injection braking are shown in the following table.
b1-07
Operation selection
after switching to
remote mode
Used to set the operation mode
by switching to the Remote
mode using the Local/Remote
Key.
0: Run signals that are input
during mode switching are
disregarded. (Input Run
signals after switching the
mode.)
1: Run signals become
effective immediately after
switching to the Remote
mode.

b2-01
Zero-speed level (DC
injection braking
starting frequency)
Used to set the frequency
which starts DC injection brak-
ing in 1% units when decelera-
tion to stop is selected.
When b2-01 is less than E1-09,
E1-09 becomes the DC injec-
tion braking starting frequency.
* The factory setting will change
when the control method is
changed.

DC injection braking
time at start
Used to set the time to perform
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 performed.
