Homing | Parameter setting
9.5.1.4 Homing to end stop
By selecting the homing modes 14 & 15, homing to end stop can be executed as follows:
1. The drive travels with reduced torque in positive direction (mode 14) or negative
direction (mode 15).
2. When the drives hits an end stop so that the torque limit set in C02649 is exceeded for
the period of time defined in C02650 , the reference is set.
– When a reference offset is set, it is traversed by this offset with correct sign.
9.5.1.5 Connection of reference switch
For the homing modes with reference switch, the control input HM_bHomingMark of the
system block LS_Homing must be connected to the digital input which is connected to the
reference switch.
9.5.1.6 Touch probe interface configuration
The touch probe channel to be used for homing with touch probe detection is selected in
the »Engineer« on the Application parameter tab in the overview  dialog level. All basic
functions  Homing  TP interface.
r The setting carried out in this parameterisation dialog directly affects the setting of
C02651 ("Ref. touch probe configuration") and vice versa.
r For a direct setting of C02651 (e.g. with keypad) the following table lists the decimal
values for all possible configurations.
r Example: For selecting the touch probe channel "DIGIN 8" and response to only one
positive edge, it is required to set the decimal value "16384" in C02651 .
