25.5 FREQROL Series Inverter Side Settings

For details of the inverter, refer to the manual of each
series.
25.5.1 Connecting to FREQROL-
S500, S500E, or F500J 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
Parameters corresponding to inverter
destination
RS-485 port Pr.79, n1 to n7, n10 to n12
(2) Communication settings of inverter
Set the following parameters using the PU (parameter
unit). Set Pr.30 (Extended function selection) to 1 [With
display] 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.
*3 Inverter default values (No need to change)
*4 When being monitored from the GOT, the parameter n1
through n7 correspond with Pr.331 through Pr.337, and the
parameter n10 through n12 correspond with Pr.340 through
Pr.342.
Numbers in brackets show the parameter number when the
parameter unit is in use.
