Braking time to b2-13.

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 without regenerative operation. When
the run command is removed, the drive will baseblock (turn off its output) for the minimum
