Example 2: Speed command 2 is specified with the following format.
G31 X100 F200 F100 (mm)
General input 1
X-axis speed
200
0
The speed control of the X axis is performed and the X axis moves at 200 mm/s
until general input 1 is turned ON. The speed of the X axis will decelerate to the
speed specified by speed command 2 (i.e., 100 mm/s) and the X axis will move
for 100 mm for positioning from the position where general input 1 was turned
ON.
There is no difference in acceleration/deceleration time between the G31 and
G00 functions. The acceleration/deceleration time usually set automatically is
proportional to the ratio of the speed command to the maximum feed rate. Refer
to the following Operation Examples.
Refer to the following for the relationship between interrupt inching axes and
general inputs.
Axis
X
Y
The feed rate operation depends on whether the origin is defined or not.
With defined origin:
With undefined origin:
Note The previous G01, G02, and G03 function will operate in stop mode instead of
pass mode if this function is executed.
An error will result if the G31 function is executed if the value of speed command
2 is the same as or larger than that of speed command 1. Make sure that the
value of the speed command 1 is larger than of speed command 2.
The value of a speed command must be the same as or less than the maximum
feed rate. If the value is larger than the maximum feed rate, the axis will move at
maximum feed rate and the override will be ignored.
The following positioning curves are obtained according to the speed and move-
ment of the axis if a general input is turned ON.
Without Speed Command 2
1. A general input is turned ON while the axis is moving at constant speed, but
the deceleration time is extremely short because the speed is high and the
movement is small.

The soft limit is valid and the current position is always
refreshed.
The soft limit is invalid and the current position will be
set to 0 when the operation starts or a general input is
turned ON.
