b) When two or more inverters are connected
Up to 10 inverters can be connected through RS-422.
- For connection between the GOT-F900 and the distributor, refer to a) on the previous page.
- For connection between the distributors, prepare connectors and cables while referring to section
13.8 later. Do not use the commercial straight connection type Ethernet 10BASE-T cable
(Category 3 or 5). (if this cable is used, inverters will have a short circuit because the pins number
2 and 8 are connected to power supply.)
- Sample products (connector, cable, and distributor) are introduced in Cable Diagram in this
chapter.
The A500 Series can be connected using the PU port or the option for computer link connection.
Though the port of the S500 Series is the RS-485 communication port, it is called "PU port" in this
manual.
c) Attaching a terminal resistor
Communication may be affected by reflection depending on the transmission speed and the
transmission distance. If communication is hindered by this reflection, provide a terminal resistor.
- When the PU port or the RS-485 port is used for connection
Attach a terminal resistor between the pin number 3 (RDA) and the pin number 6 (RDB).
Because the terminal resistor cannot be attached, use the distributor. Attach the terminal
resistor only to the inverter located farthest from the GOT-F900. (terminal resistor: 100
Ω
1/2W)
- When the FR-A5NR is used for connection
Attach a terminal resistor chip (included with the FR-A5NR) between the terminals RDB and
RDR of the last inverter.
