4. MODBUS REGISTERS
4.4 Point Table Setting (Address: 2801h to 281Fh)
Point table data can be read and written.
4.4.1 List of registers
Point table data can be read and written from/to the following registers. For details of point tables, refer to
"MELSERVO-JE-_A Servo Amplifier Instruction Manual (Positioning Mode)".
Address
Point Table No.1
2801h to
to No.31 (Point
281Fh
table No.1 to
No.31)
Note 1. This item is enabled only at reading. At reading, "07h" is returned.
2. M code will be available in the future.
4.4.2 Directions for use
Read point table data using the function code "03h" (Read Holding Registers). At this time, "07h" is returned
to Number of entries. Write point table data using the function code "10h" (Preset Multiple Registers). Set
"00h" or "07h" for Number of entries. Reading and writing of the point table data are executed by each point
table number. Thus, changing only position data of the particular point table number cannot be performed. In
that case, overwrite all the setting data values of the particular point table number with new data.
Data cannot be continuously read and written from/to these registers. Set values for each point table
number.
Even though setting values are changed with these registers, the set values are deleted at power-off if no
setting for holding values is configured. To hold setting values even after power-off, configure the setting to
save the values in EEP-ROM using Store Parameters (Register: 1010h) after the setting values are
changed.
4.5 Writing Command to EEP-ROM (Address: 1010h)
Parameter and point table setting values can be saved in EEP-ROM.
