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 141 , Setting 2: External Reference 1/2 Selection on page 142
and o2-01: LO/RE (LOCAL/REMOTE) Key Function Selection on page 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.
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.
■
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.
