[Md.29] Speed-position switching control positioning amount
This area stores the movement amount for the position control to end after the control is switched to the position control with
the speed-position switching control. Multiplying the stored value by the following converted value enables the monitoring of
the converted value in each unit.
When [Da.2] Control method is the speed-position switching control (reverse run), a negative value is stored.

Buffer memory address
The following table shows the buffer memory address of this area.
[Md.30] External I/O signal
This area stores the on/off state of external I/O signals.
Values are stored in the bits corresponding to each external I/O signal. The following table shows the assignment of each
external I/O signal.
The update cycle of this area is 0.88ms.
■
Buffer memory address
The following table shows the buffer memory address of this area.
If 1: Pre-analysis mode is set for [Cd.43] Analysis mode setting and Positioning start signal [Y10, Y11, Y12,
Y13] is used as the start trigger, the external command signal (CHG) is disabled from when the positioning
data analysis starts until a pulse input starts by inputting the start trigger. Thus, the external command signal
([Md.30] External I/O signal: b4) is fixed to 0 during that time.
