■11. Connecting FREQROL-A800, F800 series
Configure the inverter communication settings by one of the following three methods.
To automatically reconfigure the GOT side communication settings to the inverter side communication settings in
batches and to perform the automatic connection, refer to the following.
➠
(2) Communication settings of inverter (Automatic connection)
To automatically reconfigure the GOT side default communication settings to the inverter side communication settings
in batches, refer to the following.
➠
(3) Automatic setting with Pr.999
To manually reconfigure the GOT side communication settings to the inverter communication settings, refer to the
following.
➠
(4) Communication settings of inverter (Manual setting)
Be sure to perform the inverter reset after updating each parameter.
(1) Communication port and corresponding parameters
GOT connection destination
PU connector
RS-485 terminal
(2) Communication settings of inverter (Automatic connection)
When [Automatic Negotiation] is set to [Yes] in the GOT communication settings, the inverter parameters are
reconfigured to the GOT communication settings.
Set the station number settings (Pr.117 and Pr.331) and the protocol selection (Pr.549) in advance.
To use the PLC function, set the PLC function operation selection (Pr.414) in advance.
Before performing the automatic connection, connect all the GOTs and the inverters.
After the automatic connection is performed, if a station is added or changed, or the communication settings are not
reconfigured normally, change the settings with the automatic batch parameter setting (Pr.999) separately.
If the inverter power turns off while the automatic connection is executed, execute the automatic connection on the
GOT again.
If the automatic connection fails, a communication timeout error occurs.
If the automatic connection succeeds, the GOT normally starts communicating with each station.
The following shows the parameters to be reconfigured by the automatic connection.
PU communication speed/RS-485 communication speed
PU communication stop bit length/RS-485 communication stop bit length
PU communication parity check/RS-485 communication parity check
Number of PU communication retries/RS-485 communication retry count
PU communication check time interval/RS-485 communication check time interval
PU communication waiting time setting/RS-485 communication waiting time setting
PU communication CR/LF selection/RS-485 communication CR/LF selection
(3) Automatic setting with Pr.999
Setting Pr.999 as shown below automatically configures the communication settings to the default communication
settings of the GOT side collectively.
