(1) Direct positioning operation to target position 1.
Input a pulse quantity of 8000 [pulse], a pulse frequency of
2400 [pulse/s], acceleration of 0.01 [s],
↓
Travels to target position 1
↓
When the travel is completed, "INP" output is ON.
↓
(3) BUSY output is OFF
↓
Travel to target position 1 is completed
↓
(4) Target position 2 is commanded
Pulse; 4800, Pulse frequency: 8000 [pulse/sec])
Acceleration time 0.05[s], deceleration time 0.05[s] This
pulse is input to “NP-”
↓
Travels to target position 2
↓
(5) When the travel is completed, "INP" output is ON.
↓
(6) "BUSY" output is OFF
↓
Travel to target position 2 is completed.
9. Operation (example)
9.1 Positioning operation
Calculation example of the travel amount (pulse) and travel speed (pulse frequency) when the electronic
gear ratio is 1/1 (Recommended value) which are set with basic parameter "Undefined No. 11" "Undefined
No.12".
■ Setting example of pulse signal
Actuator lead: 10[mm/rotation], electronic gear (denominator): 1, electronic gear (numerator): 1
2 pulse mode (Pulse input for each direction)
Target position1: Travel amount 100mm Travel speed 30mm/s
Acceleration 3000mm/s
2
Deceleration 3000mm/s
2
Target position2: Travel amount 60mm Travel speed 100mm/s
Acceleration 2000mm/s
2
Deceleration 2000mm/s

■ Calculation example
Travel amount (Pulse amount[Pulse])
= Encoder resolution [Pulse/ rotation] x electronic gear [1/1] / Actuator lead[mm/ rotation] x travel amount
[mm]
Travel speed (pulse frequency [pulse/sec])
= (Encoder resolution [Pulse/ rotation] x electronic gear [1/1] / Actuator lead[mm/ rotation]) x travel speed
[mm/s]
Acceleration / deceleration time [s]
= Travel speed[mm/s] / Deceleration or acceleration speed [mm/s

]
<Calculation example of target position 1>
Travel amount: 800 x 1 / 10 x 100 = 8000[pulse]
Travel speed: 800 x 1 / 10 x 30 = 2400 [pulse/sec]
Acceleration / deceleration time: 30 / 3000 = 0.01 [s]
