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.

Pr.53
Zero point return acceleration time selection
Set which of "acceleration time 0 to 3" to use for the acceleration time during zero
point return.
0 : Use the value set in "
Pr.8 Acceleration time 0".
1 : Use the value set in "
Pr.26 Acceleration time 1".
2 : Use the value set in "
Pr.27 Acceleration time 2".
3 : Use the value set in "
Pr.28 Acceleration time 3".
Pr.54
Zero point return deceleration time selection
Set which of deceleration time 0 to 3" to use for the deceleration time during zero
point return.
0 : Use the value set in "
Pr.9 Deceleration time 0".
1 : Use the value set in "
Pr.29 Deceleration time 1".
2 : Use the value set in "
Pr.30 Deceleration time 2".
3 : Use the value set in "
Pr.31 Deceleration time 3".
