Normal Parameters Area
This area is used to map the External Device’s user constant parameters. The register number is defined by adding
the Pn number and the offset value. The normal parameters area offset value is 0000H.
For details on the Pn number and register mapping, please refer to the manual of the External Device.
Temporary Parameters Area
This area is used to map the External Device’s user constant parameters. The register number is defined by adding
the Pn number and the offset value. The temporary parameters area offset value is 1000H.
For details on the Pn number and register mapping, please refer to the manual of the External Device.
Since writing to Temporary Parameters Area is run in volatile memory (such as RAM), values are cleared when
the External Device is turned OFF.
If there is an operation, such as servo tuning, that requires an extreme number of write operations to memory,
running the operation in the Temporary Parameters Area generates the following advantages.
•
You can increase the life of non-volatile memory.
•
You can reduce processing time.
Operation
Description
Read
Reads volatile memory such as RAM for values. Unable to read values from non-volatile
memory such as EEPROM.
Write
Writes values to volatile memory such as RAM, and non-volatile memory such as EEPROM.
• You cannot run consecutive reads from, or consecutive writes to, different register groups.
Example: When consecutively reading from or writing to 07FFH to 0800H, the message "Data
Consistency Error (33H)" or "Access Denied Error (31H)" is displayed.
• If you specify a nonexistent register number, the message "Access Denied Error (31H)," is
displayed.
Operation
Description
Read
Reads volatile memory such as RAM for values.
Write
Writes values to volatile memory such as RAM.
• You cannot run consecutive reads from, or consecutive writes to, different register groups.
Example: When consecutively reading from or writing to 17FFH to 1800H, the message "Data
Consistency Error (33H)" or "Access Denied Error (31H)" is displayed.
• If you specify a nonexistent register number, the message "Access Denied Error (31H)," is
displayed.
