KEYENCE GV Series - Manual (Page 8)

8 GV-IM-E
„ 1. Response speed setting
The response speed is the time from when the sensor head starts detection
until the value at the detection position is established as a comparator value.
* "20" for GV-H1000 (L) only.
„ 2. Output mode setting
Sets the control output mode for each control output.
N.O. (normal open) and N.C. (normal close) operate in the following
manner.
„ 3. Operation mode selection
Sets the operation mode.
„ 4. Clamp function setting
Set the operations when distance detection cannot be performed (such as
when the detection object does not enter the detection range, or when there is
insufficient light intensity).
„ 5. (6.) Delay timer setting
Individual delay timers can be set for channels 1 and 2.
„ 7. Hysteresis setting
Sets the hysteresis for judgment with control outputs 1 and 2.
The hysteresis setting range and default value are as follows when "Usr" is
selected.
„ 8. External input function setting
Sets the function assigned to the external input (pink line).
The minimum external input time is 20 ms.
z External shift input
When external input is input, the current value is shifted by the value set for shift
target value.
(For information about the shift target value, see "9. Shift target value setting".)
z Bank switching input
When keylock is set for the amplifier, the bank switches with input to the external
input.
(For more information about bank switching, see "Bank switching".)
When edge hold mode (A-1 mode) is set, switching banks with the external
input resets the current value to 0.
z Timing input
Comparator output is only output over control output 1 when external input is
on.
The timing input indicator on the sensor amplifier lights up.
Control output 2 continues to output comparator output, regardless of
whether timing input is on or off.

Setting item Description Default value
on
Outputs the comparator output with the
detection value obtained immediately before
the distance was judged to be not detectable.
The current value display and LED bar
display are also saved for the immediately
preceding value.
If distance detection can be performed, then
the hold is released.
oFF
When the distance detection cannot be
performed and "---" is displayed, the
comparator output operates in the same way
as if a detection object appears at the
farthest point of the detection range.
