Minimum spacing

Note
Extension of the data transmission time if distance values are undershot
If the distance values specified in the tables are undershot, it is possible that the inductive
fields will be affected. In this case, the data transmission time can increase unpredictably or
a command is aborted with an error.
For this reason, please observe the values in the tables.
