Interrupt inching is used to perform speed control until an external signal is input
and to perform positioning control for inching with the external signal.
Interrupt inching can be performed either at constant speed or two speeds.
In the following example, the X axis is moved 100 mm at 200 mm/s.
General input 1
X-axis speed
In the following example, the X axis is moved 100 mm while the speed of the X
axis is decelerated to 100 mm/s from 200 mm/s.

Note 1. Interrupt inching can move a single axis only.
2. An external signal for interrupt inching is input to general inputs 1 and 2 of
the MC Unit.
General input 1
General input 2
In positioning actions, operating speed is accelerated gradually at the beginning
and decelerated gradually toward the end to achieve smooth movement. For the
MC Unit, either a trapezoidal curve or an S curve can be used as the accelera-
tion/deceleration curve for the starting/stopping operations for each axis.
The acceleration time and deceleration time can be set separately.
Note Refer to the MC Support Software Operation Manual to set the acceleration/de-
celeration curve and acceleration/deceleration times.
