YASKAWA GA700 Technical Manual page 599

The drive performs Zero Speed Control again for the time set in b2-04 when the Stop command is entered (or
when the Run command is switched OFF).

b1-06: Digital Input Reading
No.
Name
(Hex.)
b1-06 Digital Input Reading
(0158)
0 : Input status is read once
Reads the state of the terminal once. Any changes to the state of the terminals are read immediately.
The drive can respond more quickly to changes in the sequence, but there may be problems due to noise.
1 : Input status is read twice
Reads the state of the terminal twice. Any changes to the state of the terminals are read twice to make sure the
reading is the same.
The drive is less responsive compared to reading the sequence once, but this prevents problems caused by noise.
■
b1-07: LOCAL/REMOTE Run Selection
No.
Name
(Hex.)
b1-07 LOCAL/REMOTE
Run Selection
(0186)
This parameter interlocks the drive, preventing accidents that might otherwise occur from the motor suddenly
rotating when switching the source of the Run command.
Press on the keypad or set H1-xx = 1, 2 [MFDI Function Select = LOCAL/REMOTE Selection, External
reference 1/2 Selection] and turn the terminal ON/OFF to switch the RUN command source.
0 : Cycle existing RUN command
The drive will not operate the motor even if a Run command is already enabled when switching between Run
command sources.
If the drive is already operating the motor, then shut the Run command OFF to stop the motor. Re-enter the Run
command to begin operation again.
1 : Accept existing RUN command
The drive will begin operating the motor if a Run command is already enabled when switching between Run
command sources.
The drive will continue operating the motor if it is already doing so.
WARNING! Sudden Movement Hazard. When using a 3-Wire sequence, set the drive to 3-Wire sequence and set b1-17 = 0
[Run Command at Power Up = Disregard Existing RUN Command] before wiring the control terminals so the drive will not
accept a Run command at power up. The motor may rotate in reverse when the drive is powered up if the drive is wired for a 3-
wire sequence but set up for a 2-wire sequence (default) and b1-17 = 1 [Accept Existing RUN Command]. Failure to comply
could cause death or serious injury from moving equipment.

Selects if the drive should read the sequence input (FWD/REV, multi-
function input) command once or twice to prevent problems from noise.
V/f CL-V/f OLV CLV AOLV
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 to which the source is being switched. In this case, use parameter
b1-07 to determine how the Run command is treated.
