EM730/EM730E series inverters have a fixed-length counting function, as shown in Fig.
7-40. The length counting function is performed by entering the length information from the
digital input terminal in the pulse form and then setting the related function code. The final
length count information can be outputted by the digital output terminal for other purposes (e.g.
DI/VX input as the stop command). Users can also view the real-time length count via F18.34.
The length resolution can be set by F16.13. In case of any change in the length resolution,
F16.01 will change accordingly. For example, if F16.13 is set to 0:1m, the setting range of
F16.01 is 1-65535m.

Principle of fixed-length counting: The length detection sensor converts the length
information into pulse information. The DI terminal collects the number
N
of input pulses.
