OUTLINE

Connection and Parameter Setting

1.4.5 Connection through GOT (FA transparent function)

Using FA transparent function of GOT1000 series, connecting inverter to FR Configurator is available through GOT.

FA transparent function enables reading, writing and monitoring of programmable controller of Mitsubishi Electric Corporation

through GOT, while connecting Mitsubishi programmable controller and PC.

Serial port or USB is used for connecting between FR Configurator and GOT. RS-422 is used for connecting between GOT

and inverter.

[Example of RS-485 terminal connection]

[Example of PU connector connection (FR-E700(SC))]

GOT RS-422 communication unit (GT15-RS4-9S) is required. When using USB for connecting with GOT, use dedicated cable

GT09-C30USB-5P or GT09-C20USB-5P.

The number of connectable inverters depends on the GOT. Refer to GOT1000 series connection manual for details of RS-422

connection and compatible version of GOT.

Note

Do not perform the following operation during FA transparent function is valid and FR Configurator is ONLINE.

• Online operation (project download, etc.) from GT Designer/GT Designer2 to GOT

• Online operation to programmable controller CPU by using FA transparent function of GX Developer

When using FA transparent communication, communication error (Time Out) may occur when FR Configurator starts

communication during Time Out occurrence in GOT (when GOT is monitoring the inverter which is not connected). In

that case, set the Time Out value more than the following. (Refer to page 49)

Time Out value of GOT[s] x (Retry count of GOT + 1) x 3 x 1000[ms] (500ms increments)

If the value above is more than 30[s], make adjustment to "Time Out value"[s] and "Retry count" of GOT to make the

value above become less than 30[s]. Refer to page 49 for communication setting.
