(2) A proper acceleration is determined under the condition
that the acceleration change must be about the same as
the setting so that parameter changes do not cause
considerable shock to the machine, that is:

=
The acceleration change time is regarded to be the sum of
the acceleration change time of bell-shaped
acceleration/deceleration and the time constant of
acceleration/deceleration after interpolation, and the
acceleration A' for the acceleration/deceleration before
interpolation is determined as follows:

A: Acceleration for the acceleration/deceleration before
interpolation
Tc : Time constant of acceleration/deceleration after
interpolation
Acceleration/deceleration is performed using T2' and A',
determined as described above.

# 3 BCG The bell-shaped acceleration/deceleration time constant change function in
AI Contour control mode or AI Nano contour control mode is:
0: Disabled.
1: Enabled.
In AI High Precision Contour control mode or AI Nano High Precision
Contour control mode, parameter BCG (No.19501#6) should be set.
