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

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]
