Setting value, setting range
Value set with peripheral
device
The setting value range differs depending on the " Pr.11
Stepping motor mode selection" or " Pr.1 Unit setting".
Here, the value within the [Table 1] range is set.
1 to 300 (%)
0 : Zero point return speed
0 to 65535 (ms)
Pr.55 Zero point shift amount
Set the amount to shift (move) from the position stopped at with machine zero
point return.
* The zero point shift function is used to compensate the zero point position
stopped at with machine zero point return.
If there is a physical limit to the zero point position, due to the relation of the near-
point dog installation position, use this function to compensate the zero point to an
optimum position.
