Select the applicable stopping method for the application from these options:
0 : Ramp to Stop
When you enter the Stop command or turn OFF the Run command, the drive ramps the motor to stop.
The drive ramps the motor to stop as specified by the deceleration time. The default setting for the deceleration
time is
C1-02 [Deceleration Time 1] . The actual deceleration time changes as the load conditions change (for
example, mechanical loss and inertia).
1 : Coast to Stop
When you enter the Stop command or turn OFF the Run command, the drive turns OFF the output and coasts the
motor to stop.
Load conditions will have an effect on the deceleration rate as the motor coasts to stop (for example, mechanical
loss and inertia).

As a safety precaution, when the drive is in Programming Mode, it will not respond to a Up/Down command.
This parameter helps prevent accidents that can occur if the motor starts to rotate because the drive received a Up/
Down command from an external source while the user is programming the drive. You can also set the drive to
not show the Programming Mode when a Up/Down command is active.
