User area read/write method
1.12 User area read/write method
Inverter parameters Pr.506 to Pr.515, Pr.826 to Pr.865 can be used as user parameters.
Since this parameter area and the devices used with the PLC function, D110 to D159,
are accessible to each other, the values set in Pr.506 to Pr.515, Pr.826 to Pr.865 can be
used in a sequence program. The result of operation performed in the sequence
program can also be monitored using Pr.506 to Pr.515, Pr.826 to Pr.865 .
1.12.1 User parameter read/write method
User parameter (Pr.506 to Pr.515, Pr.826 to Pr.865) and device (D110 to D159) data can
be read/written freely. Data transfer between Pr.506 to Pr.515, Pr.826 to Pr.865 and D110
to D159 is executed automatically.
1) User parameter write processing and device write processing
When values are written to Pr.506 to Pr.515, Pr.826 to Pr.865 using the FR-PU04/FR-
PU07(-01) or computer link communication, they are written to the parameter
storing RAM area and EEPROM area, and further to D110 to D159 simultaneously.
2) User parameter read processing and device write processing.
When values are written to D110 to D159 from the PLC function side, they are
written to the parameter storing RAM area (Pr.506 to Pr.515, Pr.826 to Pr.865) and
read using the FR-PU04/FR-PU07(-01) or communication(RS-485 or
communication option). (Since data are not written to the EEPROM, making power-
on reset returns the data to the original values.)
3) Processing performed at inverter reset or power restoration
When the inverter is reset, the Pr.506 to Pr.515, Pr.826 to Pr.865 values stored in the
EEPROM are transferred to the RAM area and D110 to D159.

Example of using the user parameter area
When the timing is to be changed for machine adjustment using D110 that
stores the timer setting, setting
Pr. 506 without modifying the program enters
the set data into D110, enabling adjustment.
