NOTE
• Do not perform the following operation while the FA transparent function is valid and FR Configurator2 is in online mode.
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 or GX Works2
• When using FA transparent communication, communication error (timeout) may occur when FR Configurator2 starts
communication during timeout occurrence in a GOT (when a GOT is monitoring the inverter which is not connected). In that
case, set the timeout time value more than the following. (Refer to
.)
Timeout value of GOT [s] × (Retry count of GOT + 1)
If the value above is more than 30 [s], make adjustment to "Timeout value" [s] and "Retry count" of GOT to make the value
above become less than 30 [s].
GOT2000 series automatic recognition
• When a GOT2000 model is connected, the parameters required for the GOT connection are automatically changed by
setting the automatic recognition in the GOT2000 model.
• Set the station number (
Pr.117
or
Pr.331
) of the inverter before the automatic recognition is performed.
• Connect all the stations of inverters with GOT before the automatic recognition is performed. The inverter newly added
after automatic recognition will not be recognized automatically. (When an inverter is added, perform the initial setting in
Pr.999 Automatic parameter setting
or set the automatic recognition on the GOT side again.)
NOTE
• If the automatic recognition cannot be performed, initial setting in
Pr.999
is required.
• For connecting a GOT2000 model to the RS-485 terminal block on the inverter, set
Pr.549 Protocol selection
= "0 (initial
value) or 1".
• For connection to a device other than the GOT2000 series, initial setting in
Pr.999
is required.
• For details, refer to the GOT2000 Series Connection Manual (Mitsubishi Product).
Related parameters for connection through GOT
Set communication-related parameters automatically as follows. For connection through GOT, set
Pr.123 PU communication
waiting time setting
= "0",
Pr.337 RS-485 communication waiting time setting
= "0". For connection to the PU connector,
set
Pr.999 Automatic parameter setting
= "12". For connection to the RS-485 terminals, set
Pr.999
for Ethernet-related parameters.
List of related parameters
Availability, initial values, and setting ranges of parameters differ depending on the inverter. For details, refer to the Instruction
Manual of the relevant model.
