3. Functional description
In this section, functions added by the installation of this F10M option unit, on top of the standard inverter functions, are described.
3.1 F10M communication function
Through the communication network, drive and stop control and concentrated monitoring control of operation status can be carried out by the programmable controller and industrial computer.
3.1.1 Connection of transmission cable z SL1, SL2, SG
Transmission path is constructed by the shielded twisted pair cables as shown in the figure below.
Be sure to connect SL1, SL2 and SG mutually to another station. Note that wrong connection will not bring the correct transmission.
z SHD
Connect a shield of twisted pair cable to the transmission terminal SHD of each station and set up a class 3 or equivalent grounding work in an arbitrary station.
z Terminal
Set terminal resistors at both sides of the system for the sake of impedance matching. Connect terminal resistor (120Ω-1/2W) between the terminal block SL1 and SL2.
(As for the master station (MS), terminal resistor can be combined by connecting L1 and TERM.)
