· DC Injection Braking Stop (B1-03 = “2”)
Upon removal of the FWD (REV) run command, the motor brakes to stop, according to the DC injec-
tion braking time at stop set in B2-04. If this value is set to “0” (factory default), DC injection braking
is disabled, and the motor coasts to stop. When choosing this function, note that the actual stop time
from maximum frequency is the time set in B2-04 multiplied by 10 (see the figure above). This stop-
ping method is disabled during flux vector control.
· Coast to Stop with Timer 1 (B1-03 = “3”)
After a stop command is given, a run command is not accepted while the coast to stop timer C1-02
elapses (same as Decel Time 1). After the timer runs out, another run command must be given for the
inverter to begin acceleration. This stopping method is disabled during flux vector control.
