Stopping Methods
6-
11
The operation after stopping depends on the setting of b1-05 when flux vector control is selected (A1-02 = 3).

Coast to Stop
If the stop command is input (i.e., the run command is turned OFF) when b1-03 is set to 1, the Inverter output
voltage is interrupted. The motor coasts to a stop at the deceleration rate that counterbalances damage to the
machine and inertia including the load.
