Switch-on and switch-off positions depend on the travel direction:
S P x - S T A T x
Definition of a switch-on and switch-off position according to the travel direction
Mode 2: Centre point with switching range
C1645 = set 1 (SP1)
C1655 = set 1 (SP2)
SPx-STATx
Centre point with switching range
•
INx-1 determines the centre point.
•
INx-2 determines the switching range around the centre point.

Hysteresis

This function is available only for the FB SP2.
Purpose
Avoids indefined switching of the output signals (in standstill the drive is located exactly on a
switching point).
Function
•
The hysteresis is entered via C1658.
– The setting is effective for SP2-STAT1 ... SP2-STAT8.
