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 Drive 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.
Run command
Output frequency
After the stop command is input, run commands are ignored until the Minimum Baseblock Time (L2-03) has
elapsed.
