F500L series

Communication settings
Make the communication settings of the inverter.
Be sure to perform the inverter reset after updating
each parameter.
(1) Communication port and corresponding parameters
GOT connection destination Parameters corresponding to inverter
PU connector
FR-A5NR (Option unit) Pr.79, Pr.331 to Pr.337, Pr.340 to Pr.342
(2) Communication settings of inverter
Set the following parameters using the PU (parameter
unit). Set Pr.160 (user group read selection) to 0 [All
parameters can be accessed for reading and writing.]
before making the parameter settings.
Do not change these parameters, even though they
can be monitored from the GOT. If they are changed,
communication with the GOT is disabled.

When changing the settings on the GOT, be sure to change
the parameters on the inverter to correspond with the GOT
settings.
