■ b1-06: Digital Input Reading
No.
(Hex.)
Name Description
Default
(Range)
b1-06
(0185)
Digital Input Reading
Sets the number of times that the drive reads the sequence input command to prevent malfunction
because of electrical interference.
1
(0, 1)
0 : Single Scan
The drive reads the terminal status one time. The drive immediately reads all changes to the terminal status.
This setting lets the drive quickly respond to changes in the sequence, but noise can cause malfunction.
1 : Double Scan
The drive reads all changes to the terminal status two times to make sure that the reading is the same.
The drive responds slower than when it reads the sequence one time, but this setting prevents malfunction because
of electrical interference.
■ b1-07: LOCAL/REMOTE Run Selection
No.
(Hex.)
Name Description
Default
(Range)
b1-07
(0186)
LOCAL/REMOTE Run
Selection
Sets drive response to an existing Run command when the drive receives a second Run command
from a different location.
0
(0, 1)
This parameter interlocks the drive to help prevent accidents that can occur if the motor starts to rotate because the
Run command source changed.
To switch the RUN command source, push on the keypad or set H1-xx = 1, 2 [MFDI Function Selection =
LOCAL/REMOTE Selection, External Reference 1/2 Selection] and activate/deactivate the terminal.
0 : Disregard Existing RUN Command
If a Run command is enabled when you switch between Run command sources, the drive will not operate the
motor.
When the drive is operating the motor, turn OFF the Run command to stop the motor. Enter the Run command
again to start operation.
1 : Accept Existing RUN Command
If a Run command is enabled when you switch between Run command sources, the drive will start to operate the
motor or continue to operate the motor.
WARNING! Sudden Movement Hazard. When you use a 3-Wire sequence, set A1-03 = 3330 [Initialize Parameters = 3-Wire
Initialization] and make sure that b1-17 = 0 [Run Command at Power Up = Disregard Existing RUN Command] (default). If you
do not correctly set the drive parameters for 3-Wire operation before you energize the drive, the motor can suddenly rotate
when you energize the drive.
■ b1-08: Run Command Select in PRG Mode
No.
(Hex.)
Name Description
Default
(Range)
b1-08
(0187)
Run Command Select in
PRG Mode
Sets the conditions for the drive to accept a Run command entered from an external source when
using the keypad to set parameters.
0
(0 - 2)
As a safety precaution, when the drive is in Programming Mode, it will not respond to a Run command.
This parameter helps prevent accidents that can occur if the motor starts to rotate because the drive received a Run
command from an external source while the user is programming the drive. You can also set the drive to not show
the Programming Mode when a Run command is active.
