4) Type of fabric for sewing is set with the function setting number P088.
P088 0: Transparent fabric
1: Translucent fabric
2: Standard fabric
When the transparent fabric is selected, the sensitivity of the sensors is increased to be able to detect the
fabric with a higher transmission. On the other hand, short threads or cloth chips may be detected mis-
takenly.
Function setting No. P085: In the case the transparent fabric is selected, the value set with this function
setting number will be used as a correction value for the material-detection threshold of the sensors.
P085 Setting range: 0 - 800
When the translucent fabric is selected, the sensitivity of the sensors becomes medium to be able to de-
tect the translucent fabric.
Function setting No. P086: In the case the translucent fabric is selected, the value set with this function
setting number will be used as a correction value for the material-detection threshold of the sensors.
P086 Setting range: 0 - 800
When the standard fabric is selected, the sensitivity of the sensors is decreased to detect the fabric with
a lower transmission. Likelihood of false detection of short threads or cloth chips is reduced.
Function setting No. P087: In the case the standard fabric is selected, the value set with this function set-
ting number will be used as a correction value for the material-detection threshold of the sensors.
P087 Setting range: 0 - 800
The final thresholds of the sensors are obtained by reducing the correction values for the material-detec-
tion thresholds set with the function setting numbers P085 to P087 from the material-detection thresholds
set with the function setting numbers P079 to P081. If the values detected by the sensors are smaller
than the final thresholds, the sensors will confirm the presence of a fabric.
