Example for setting " Pr.52 Setting for the movement amount after near-point dog ON"
When " Pr.7 Speed limit value" is set to 200kpulse/s, " Pr.48 Zero point return speed" is set to 10kpulse/s, " Pr.49 Creep
speed" is set to 1kpulse/s and the deceleration time is set to 300ms, " Pr.52 Setting for the movement amount after near-point
dog ON" is calculated as shown below.
