Bit 1: POS_ERR
Bit 0: POS_ACK
Actual value
(linear axis: 0 to 16 777 215; rotary axis: 0 to end of rotary axis - 1)
Meaning
Defines the distance from the destination at
which the drive is slowed down from creep feed
to 0.
If the switch-off difference ≥ the switchover
difference, there is no switchover point. There is
no slowdown from rapid feed to creep feed.
Defines the distance from the destination at
which the drive is slowed down from rapid feed
to creep feed.
