5. HOW TO USE THE PROGRAM
5 - 14
1) Program example 1
When using the absolute value travel command under the absolute value command method
Command Description
SPN (500) Servo motor speed 500 [r/min] a)
STA (200) Acceleration time constant 200 [ms] b)
STB (300) Deceleration time constant 300 [ms] c)
MOV (500) Absolute value travel command 500 [×10
STM
μm] d)
SPN (1000) Servo motor speed 1000 [r/min] e)
MOVA (1000) Absolute value continuous travel command 1000 [×10
STM
μm] f)
MOVA (0) Absolute value continuous travel command 0 [×10
STM
μm] g)
STOP Program stop

d) Absolute value
travel command
(500 × 10
STM
μm)
e) Servo motor
speed
(1000 r/min)
c) Deceleration time

f) Absolute value
continuous travel
command
(1000 × 10
STM
μm)
b) Acceleration time constant
(200 ms)
e) Servo motor
speed
(1000 r/min)
g) Absolute value continuous

(0 × 10
STM
μm)
Reverse rotation
0 r/min
Forward rotation
2) Program example 2 (Incorrect usage)
For continuous operations, the acceleration time constant and the deceleration time constant
cannot be changed for each different speed. Therefore, even if the "STA", "STB", and "STD"
commands are written at a speed change, the commands are invalid.
