To set the number of items, represent it as a 4-digit hexadecimal number first, set the leftmost
bit to 1, then convert the hexadecimal code into ASCII code. For example, when the number of
items is 720, represent it as hexadecimal number 02D0 Hex first, set the leftmost bit to 1 to
obtain hexadecimal number 82D0 Hex, then set ASCII code “82D0” (38 32 44 30 Hex).

Note 1. The parameter area code is divided into the following three types.
4000: Parameters in byte (8 bits) units
8000: Parameters in word (16 bits) units
C000: Parameters in long word (32 bits) units
Set the parameter area code as ASCII code “4000,” “8000,” or “C000.”
Note 2. Set the beginning address as 4-digit ASCII code. For example, to write an origin compensa-
tion value to address 8000, set “8000.”
Note 3. In “No. of items,” set the number of items in the unit specified for the parameter area code. For
example, resolution/compensation settings are parameters in byte units, so the number of
items is 1. Origin compensation values are parameters in word units, so the number of items is
1. Cam programs for cams 1 to 8 of bank 1 are parameters in byte units, so the number of
items is 720.
To set the number of items, represent it as a 4-digit hexadecimal number first, set the leftmost
bit to 1, then convert the hexadecimal code into ASCII code. For example, when the number of
items is 720, represent it as hexadecimal number 02D0 Hex first, set the leftmost bit to 1 to
obtain hexadecimal number 82D0 Hex, then set ASCII code “82D0” (38 32 44 30 Hex).
Note 4. In “Data,” set all data as ASCII code.
Example 1: Writing 200 as an origin compensation value
Parameter area code: “8000”; Beginning address: “0002”; No. of items: “8001”; Data: “0200”
Example 2: Clearing cam programs
Parameter area code: “4000”; Beginning address: “0100”; No. of items: “8001”; Data: “20”
