(3) Write “0” (OFF) to [START]. (This is to generate a rising edge in the next start.)
Query: 01 10 0000 0002 04 00000000 F3AF (13 bytes)
Response: 01 10 0000 0002 41C8 (8 bytes)
(4) Write immediate value data setting 2, which is for the next operation, as immediate value data.
The immediate value data operation follows the immediate value data read at the start (rising
edge of [START]). After operation is started, you can write the following setting as immediate
value data.
Setting 2: Immediate value position = -100000 units.
Immediate value speed = 200.00 r/min
Query: 01 10 5101 0004 08 FFFE7960 00004E20 667A (17 bytes)
Response: 01 10 5101 0004 80F6 (8 bytes)
(5) Read [INP] and check that immediate value data operation 1 is finished.
If [INP] is turned off, immediate value data operation 1 is in progress. (5) is repeated until [INP]
is turned on.

If “1
”, [INP] is turned on.
Because immediate value data operation 1 is finished, the
process proceeds to step (6).
(6) Write “1” (ON) at [START] to start positioning operation. (Immediate value data operation 2
based on immediate value data setting 2 starts.)
Query: 01 10 0000 0002 04 00000001 326F (13 bytes)
Response: 01 10 0000 0002 41C8 (8 bytes)
(7) Write “0” (OFF) at [START]. (This is to generate a rising edge at the next start.)
Query: 01 10 0000 0002 04 00000000 F3AF (13 bytes)
Response: 01 10 0000 0002 41C8 (8 bytes)
(8) Read [INP] and check that immediate value data operation 2 is finished.
If [INP] is OFF, immediate value data operation 1 is in progress. Repeat step (8) until [INP] is
turned on.

If “1
”, [INP] is turned on.
Immediate value data operation 1 is finished.
