Coast to Stop: b1-03 = 1
When the run command is removed, the drive will shut off its output and the motor will coast (uncontrolled deceleration). The motor will coast to a stop
at the rate determined by the load inertia.

Note: 1. After entering a stop command, the drive will not accept another run command until the time set to L2-03 (Minimum Baseblock Time) passes.
2. Do not enter another run command until the motor comes to a complete stop. If a run command must be entered before the motor has fully stopped, use DC Injection or
Speed Search functions to slow the motor or catch the motor before restarting. For details refer to V1000 Technical Manual.

DC Injection Braking to Stop: b1-03 = 2
DC Injection Braking stops a coasting motor without regenerative operation. When the run command is removed, the drive will baseblock (turn off its
output) for the minimum baseblock time (L2-03). Once the minimum baseblock time has expired, the drive will inject DC current into the motor windings
to lock the motor shaft. The stopping time will be reduced as compared to coast to stop. The level of DC Injection current is set by parameter b2-02 (default
= 50%). The time for DC Injection Braking is determined by the value set to b2-04 and by the output frequency at the time the run command is removed.
Note: DC Injection braking cannot be selected as a stopping method in PM Open Loop Vector Control.
