4-3
The internal speed is set in the program in Fig. 4-2.
If you execute a similar program at 80% external speed, the following results
occur.

Actual speed = external speed x internal speed
Actual speed = 80% x 50%
Actual speed = 40%
Actual acceleration = external acceleration x internal
acceleration
Actual acceleration = 64% x 25%
Actual acceleration = 16%
Actual deceleration = external deceleration x internal
deceleration
Actual deceleration = 64% x 25%
Actual deceleration = 16%
