Used to set the time to perform DC
injection braking at start in units of
DC injection 1 second.
b2-03 braking time at Used to stop coasting motor and
start restart it. When the set value is 0,
DC injection braking at start is not
performed.
Used to set the time to perform DC
injection braking at stop in units of
DC injection 1 second.
b2-04 braking time at Used to prevent coasting after the
stop stop command is input. When the
set value is 0.00, DC injection brak-
