15. INVERTER CONNECTION
15.5 FREQROL Series Inverter Side Settings
15.5.9 Connecting FREQROL-F700PJ 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
(2) Communication settings of inverter
Set the following parameters using the PU (parameter unit). Set Pr.160 (User group read selection) to 0 [The
simple mode and extended parameters can be displayed] 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.
*1 Setting items are parameter names described in the manual of FREQROL-F700 series.
*2 Settings on the GOT can be changed.
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)
HINTHINTHINT
Automatic setting with Pr.999
If Pr.999 is set as the following, the communication settings other than [PU communication station number] and
[Communication EEPROM write selection] can be automatically set in a batch to the default communication
settings of the GOT side.
*1 When monitoring the value of Pr.999, 9999 is always monitored.
