4.4 Setting Acceleration and Deceleration
The product of external acceleration and internal acceleration determines
actual acceleration and deceleration.
For example, if the following conditions are set,
external deceleration: 70%
internal deceleration: 30%
the expression below is obtained.
Actual deceleration = maximum deceleration × 0.7 × 0.3
The actual deceleration is 21% of the maximum deceleration.
The commands to set acceleration and deceleration are listed in Table 4-1.
Table 4-1 Setting Commands of Acceleration and Deceleration
Command Function
SPEED Internal speed setting
ACCEL Internal acceleration setting
DECEL Internal deceleration setting
JSPEED Internal axis speed setting
JACCEL Internal axis acceleration setting
JDECEL Internal axis deceleration setting
4.5 Example of Setting Speed and
Acceleration
The program shown in Fig. 4-1 does not set any internal speed.
If you execute this type of program at 80% external speed, the following results
occur.
PROGRAM PRO1
TAKEARM
MOVE P, P1
END
Actual speed = external speed x internal speed
Actual speed = 80% x 100%
Actual speed = 80%
Actual acceleration = external acceleration x internal
acceleration
Actual acceleration = 64% x 100%
Actual acceleration = 64%
Actual deceleration = external deceleration x internal
deceleration
Actual deceleration = 64% x 100%
Actual deceleration = 64%
