<Sequence program>
1) A program to start the positioning data No.81, No.82.
(Same program as the one in Section 6.11.6.)
2) The following programs are needed to use the external command signal (CHG) for
the speed
•
position switching.
• Write "2" to the 'external command signal function selection' of detailed
parameter 2 (1-axis buffer memory address 62).
• Write "1" to the 'external command valid' (1-axis buffer memory address 1505).
• Write "1" to the 'speed position switching enable flag' (1-axis buffer memory
address 1528).
