CF-4700A/CF-4700 Frequently Asked Questions
Question number FAQ-0313
I want to determine the vibration values for upward and downward movement using rotational tracking analysis (the measurement conditions and rotational speed range are the same for upward and downward movement, but the shape of the vibration is different for each).
Measurement conditions, schedule conditions, and judgment conditions are set in advance and saved in the panel condition memory. When the power is turned on, it is set to start with those conditions.
Switching between Shape 1 (for upward movement detection) and Shape 2 (for downward movement detection) is done using the 4LEVELCOMP function.
You can switch between four levels using DI 1 and 2. This time, we only need two levels, so we'll switch using only DI.
When both DI1 and DI2 are OFF, it will be Shape 1; when DI1 is ON and DI2 is OFF, it will be Shape 2.
DI1 and DI2 will remain in the ON or OFF state. The ON state for the other terminals will be a pulse of approximately 100 ms.
This is an example of command registration for DI3 and later versions.
