b1-07: LOCAL/REMOTE Run Selection
The drive has three separate control sources that can be switched using digital inputs (H1-oo = 1 (LOCAL/REMOTE
Selection) or 2 (External reference 1/2)) or the LO/RE key on the digital operator.
Refer to Setting 1: LOCAL/REMOTE
,
Refer to Setting 2: External Reference 1/2 Selection on page 206
(LOCAL/REMOTE) Key Function Selection on page 268
for details.
• LOCAL: Digital operator. The digital operator sets the frequency reference and Run command.
• REMOTE: External reference 1. The frequency reference and Run command source are set by b1-01 and b1-02.
• REMOTE: External reference 2. The frequency reference and Run command source are set by b1-15 and b1-16.
When switching from LOCAL to REMOTE, or between External reference 1 and External reference 2, the Run command
may already be present at the location at which the source is being switched. In this case, use parameter b1-07 to determine
how the Run command is treated.
No.

Setting 0: Run command must be cycled
When the Run command source differs between the old source and the new source (e.g., the old source was the terminals and
the new source is serial communication), and the Run command is active at the new source as the switchover occurs, the drive
will not start or the drive will stop operation if it was previously running. The Run command must be cycled at the new source
to restart the drive.
Setting 1: Accept Run command at the new source
When the Run command is active at the new source, the drive starts or continues operation if it was previously running.
WARNING!
Sudden Movement Hazard. The drive may start unexpectedly if switching control sources when b1-07 = 1. Clear all personnel
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 command input when the digital operator is being used
to adjust parameters in Programming Mode (Verify Menu, Setup Mode, Parameter Settings Mode, and Auto-Tuning Mode).
If required by the application, set b1-08 to allow the drive to run while in Programming Mode.
No.
