[Md.30] External I/O signal
If 1: Pre-analysis mode is set for [Cd.43] Analysis mode setting and [Cd.184] Positioning start signal 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.
[Md.31] Status
This area stores the on/off state of various flags.

Description
This signal, which turns on during the speed control, is used to judge whether the operation is performed under the speed
control or position control. This signal turns off at the power-on, in the position control, and during the JOG operation or
manual pulse generator operation. During the speed-position switching control or position-speed switching control, this
signal turns on only when the speed control is performed. When the speed control is switched to the position control by the
speed-position switching signal, this signal turns off. When the position control is switched to the speed control by the
position-speed switching signal, this signal turns on.
This signal is used to interlock the movement amount change function in the speed-position switching control. During the
speed-position switching control, this signal turns on when the speed control is switched to the position control. This signal
turns off when the next positioning data is processed, and during the JOG operation or manual pulse generator operation.
This signal turns on when the remaining distance is equal to or less than the command in-position width (set by a detailed
parameter). This signal remains off with the data for which the continuous path control (P11) is specified as the operation
pattern. The state of this signal is monitored every 0.88 ms. It is not monitored under the speed control or while the speed
control is in effect during the speed-position switching control or position-speed switching control. While operations are
performed with interpolation, this signal turns on only for the starting axis. (This signal turns off for all the axes at the start.)
