Setting 3: Coast to Stop with Timer
When the Run command is removed, the drive will turn off its output and the motor will coast to stop. If a Run command
is input before the operation wait time
t
expires, the drive will not rotate the motor and the Run command will need to be
cycled before operation can occur.
Figure 5.8
Figure 5.8 Coast to Stop with Timer
The operation wait time
t
is determined by the output frequency when the Run command is removed and by the active
deceleration time.

b1-04: Reverse Operation Selection
Setting parameter b1-04 to 1 instructs the drive to ignore any Reverse run commands.
Setting 0: Reverse Operation Enabled
Possible to operate the motor in both forward and reverse directions.
Setting 1: Reverse Operation Disabled
Drive disregards a Reverse run command or a negative frequency reference.
■
b1-07: LOCAL/REMOTE Run Selection
The drive has the following three separate control sources that can be switched using digital inputs or the LO/RE key on
the digital operator (for details
Refer to Setting 1: LOCAL/REMOTE Selection on page 160
External Reference 1/2 Selection on page 161
and
Refer to o2-01: LO/RE (LOCAL/REMOTE) Key Function
):
• LOCAL - The digital operator is used to set the reference and the Run command.
• REMOTE - Reference 1: The settings of b1-01 and b1-02 determine where the frequency reference and Run command
are input from.
• REMOTE - Reference 2: The settings of b1-15 and b1-16 determine where the frequency reference and Run command
are input from.
When switching from LOCAL to REMOTE, or between Reference 1 and Reference 2, the Run command may already be
present at the location the source was switched to. Parameter b1-07 can be used to determine how the Run command is
treated in this case.
No.
