5.2 b: Application
The operation wait time t is determined by the output frequency when the Run command is removed and by the active
deceleration time.
n b1-04: Reverse Operation Selection
For some applications, reverse motor rotation is not appropriate and may even cause problems (e.g., air handling units,
pumps, etc.). Setting parameter b1-04 to 1 instructs the drive to ignore any Reverse run commands.
No.
b1-04
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.
n 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
Reference 1/2 Selection on page 177
236):
• 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.
b1-07
Setting 0: Run Command Must Be Cycled
If the Run command is issued differently in the old and new control source (e.g. old - terminals, new - serial
communications) and it is active at the new source when switching takes place, the drive will either not start or it will stop
if it was running before. The Run command has to be cycled to start from the new control source.
Setting 1: Continue Running
If the Run command is active at the new control source, the drive starts or continues running. There is no need to cycle
the Run command.
WARNING! The drive may start unexpectedly if switching control sources when b1-07 = 1. Clear all personnel away from rotating
machinery and electrical connections prior to switching control sources. Failure to comply may cause death or serious injury.
n b1-08: Run Command Selection while in Programming Mode
As a safety precaution, the drive will not normally respond to a Run input when the digital operator is being used to adjust
parameters in the Programming Mode (Verify Menu, Setup Mode, Parameter Settings Mode, and Auto-Tuning). If required
by the application b1-08 can be used to changed this functionality.
No.
