[Pr.46] Home position return speed
Set the speed for home position return.
*1 The range of home position return speed when "[Pr.83] Speed control 10  multiplier setting for degree axis" is valid: 0.01 to
20000000.00 (degree/min)
*2 The range of home position return speed when "[Pr.83] Speed control 10  multiplier setting for degree axis" is valid: 1 to
2000000000 ( 10
-2
degree/min)
Set the "home position return speed" to less than "[Pr.8] Speed limit value". If the "speed limit value" is
exceeded, the error "Outside speed limit value range" (error code: 1A69H) will occur, and home position
return will not be executed. The "home position return speed" should be equal to or faster than the "[Pr.7] Bias
speed at start" and "[Pr.47] Creep speed".
[Pr.47] Creep speed
Set the creep speed after near-point dog ON (the low speed just before stopping after decelerating from the home position
return speed). The creep speed is set within the following range.
([Pr.46] Home position return speed)  ([Pr.47] Creep speed)  ([Pr.7] Bias speed at start)
*1 The range of home position return speed when "[Pr.83] Speed control 10  multiplier setting for degree axis" is valid: 0.01 to
20000000.00 (degree/min)
*2 The range of home position return speed when "[Pr.83] Speed control 10  multiplier setting for degree axis" is valid: 1 to
2000000000 ( 10

[Pr.48] Home position return retry
Set whether to carry out home position return retry.
Refer to the following for the operation of home position return retry.
