5. Example
Start speed 0 (pps)
Maximum value of speed data Nos. 1 to 15 20000 (pps)
Acceleration 100 (pps/1ms)
Deceleration 100 (pps/1ms)
∆υ
= 40000/100 = 400
∆V = 20000 x 2 = 40000
L = (∆V/R) = (40000/100) = 100

The time required between START command bit recognition and the begin-
ning of pulse output is 0.1 second or less.
Only about 10 ms is required to begin execution of positioning actions with
“single” completion codes.
The time required between CHANGE SPEED or STOP command bit recogni-
tion and the beginning of execution is at least 4 ms.
