5.2 b: Application

b1-07: LOCAL/REMOTE Run Selection
The drive has three separate control sources that can be switched using digital inputs (H1- = 1 (LOCAL/REMOTE
Selection) or 2 (External reference 1/2)) or the LO/RE key on the digital operator.

• LOCAL: Digital operator. The digital operator is used to set 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 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
When the Run command source is different in the old and 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 switch over occurs, the drive
will not start or will stop operation if it was running before. The Run command has to be cycled at the new source in
order to start the drive again.
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 running before.
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 command 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 Mode). If required by the application, set b1-08 to allow the drive to run while in the Programming Mode.
No.
b1-08
Setting 0: Disabled
A Run command is not accepted while the digital operator is in the Programming Mode.
Setting 1: Enabled
A Run command is accepted in any digital operator mode.
Setting 2: Prohibit programming during run
It is not possible to enter the Programming Mode as long as the drive output is active. The Programming Mode cannot be
displayed during Run.

b1-14: Phase Order Selection
Sets the phase order for drive output terminals U/T1, V/T2, and W/T3.
Switching motor phases will reverse the direction of the motor.
No.
b1-14
Setting 0: Standard phase order
Setting 1: Switched phase order
