· Coast to Stop (B1-03 = “1”)
Upon removal of the FWD (REV) run command, the motor starts to coast. After a stop command is
given, a run command is accepted and operation will start after the minimum baseblock time (L2-03)
elapses. If there is a possibility that a run command might be entered before the motor has come to a
stop, the speed search function (B3) or Coast to Stop with Timer 1 (B1-03 = “3”) should be employed.
· DC Injection Braking to 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 is
the time set in B2-04 multiplied by 10 (see Figure 3 above). This stopping method is disabled during
flux vector control. Braking duty cycle should allow excess motor heat to dissipate.
