3. Others (which should be set if necessary)
The table below shows parameters to be considered when using various system configuration and inverters.
For the method of use, refer to the respective inverter manual.
Parameter No.
Pr37
Pr146
Pr342
*1. This inverter communication function cannot read or write Pr37.
Set Pr37 to "0" when setting or monitoring the frequency in the PLC.
If any value other than "0" is set to Pr37 and the instruction code HFF is set to "01", the frequency may
not be set or monitored normally (in the 400 V class).
(In the 200 V and 100 V classes, the frequency may not be set or monitored normally if any value
other than "0" is set to Pr37 without regard to the setting of the instruction code HFF.)
*2. When changing the frequency from the PLC, set "1" or "9999".
