Rotation stop mode
Cut-off looks unclear when the rotation stops suddenly due to the constraint of maximum detection
time corresponding to the minimum input rotation speed. For this reason, 0 rpm display can be
forcibly set with "the cycle of the rotation speed last detected × a certain multiple".
≪
Setting value
≫
OFF (invalid)
After detection is waited for the duration of the maximum detection time
corresponding to the minimum input rotation speed, the display becomes 0 rpm.
2, 4, 8 [times] (valid)
If pulse is not detected from the cycle of the rotation speed last detected to the cycle
of the set multiple, the display becomes 0 rpm forcibly.
How to set
Example) When stopped suddenly with the setting of "4 times"
Example) When decelerated suddenly with the setting of "4 times"
