Therefore, the distance = revolution numbers X circumference = 175 X 2 π r
It also means that the motor will stop to the original position after 175 circles.
Example 2:
Assume that motor speed is 1.5Hz, the delay time at 10Hz is 10 sec (Pr.01.21=10) and the
deceleration time from 60Hz to 0Hz is 40 seconds.
The delay time at 1.5Hz is 1.5 sec and the deceleration from 1.5Hz to 0Hz is 1 sec.
The rotation speed n = 120 X 1.5 /4 (rpm/min) = 1.5/2 rpm/sec = 0.75 rpm/sec
The revolution numbers = (1.5/2X (1.5+2.5))/2 = 1.5 (revolutions)

Therefore, the distance = revolution numbers X circumference = 1.5 X 2 π r
It also means that the motor will stop after running 1.5 circles.
