At P1, 90(Nm) can be used for the
acceleration/deceleration, so set the
ratio 7717 (mm/sec
2
) to 4124
(mm/sec
2
).

At P5, 69(Nm) can be used for the
acceleration/deceleration, so set the
ratio 5916 (mm/sec

).
1.4345 = 5916/4124
With the above parameter settings, the acceleration pattern will be shown as the following
figure. The acceleration is 7716 (mm/sec
2
) in case speed is up to 32000 (mm/min) and
acceleration is calculated according to the following figure in case speed is from 32000
(mm/min) up to 48000 (mm/min).

NOTE
The values in the model

i
speed-torque
characteristic diagram are just typical ones. The
values will change depending on the digital servo
software, parameters, input voltage, and other
factors.
The optimum acceleration will, therefore, change
due to the characteristics of the machine.
