User Area Read/Write Method

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, 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.

Device	Inverter		Initial	Setting	Minimum Setting
	Parameter	Name				Data Access
No.	No.		Value	Range	Unit
D110 to	506 to 515	User	0	0 to	1	Always
D119		parameters		65535		enabled
	Inverter parameters			PLC function devices
	Pr.506 to Pr.515				D110 to D119

POINT

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.

1.9.1User 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

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.
