1.9 User Area Read/Write Method
Inverter parameters Pr.506 to Pr.515 can be used as user parameters.
Since this parameter area and the devices used with the PLC function, D110 to D119,
Since this parameter area and the devices used with the PLC function, D110 to D119,
are accessible to each other, the values set in Pr.506 to Pr.515 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.

User parameter read/write method
User parameter (Pr.506 to Pr.515) and device (D110 to D119) data can be read/written
freely. Data transfer between Pr.506 to Pr.515 and D110 to D119 is executed
automatically.
1) User parameter write processing
freely. Data transfer between Pr.506 to Pr.515 and D110 to D119 is executed
automatically.
1) User parameter write processing
When values are written to Pr.506 to Pr.515 using the FR-PU04 or computer link
communication, they are written to the parameter storing RAM area and EEPROM
area, and further to D110 to D119 simultaneously.
2) User parameter read processing
When values are written to D110 to D119 from the PLC function side, they are
written to the parameter storing RAM area (Pr.506 to Pr.515) and read using the FR-
PU04/FR-PU07 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 values stored in the EEPROM are
transferred to the RAM area and D110 to D119.

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.
