7.5.8.8 Homing mode 8 and 9
Purpose
•
Homing in all positioning modes (C1210 = 0, 1, 2).
•
Use of touch probe if the index pulse does not appear at the same place in a reproducible
form due to the mechanical constellation. The index signal can also be mechanically shifted
after a motor exchange.
•
The touch probe must be situated in direction of movement. The TP must not be assigned
before starting homing.
Directly travel to TP signal
Mode 8: Traversing direction to the positive end of the travel range limit switch
Set C1213 = 8.

Fig. 7-26 Move to TP signal
The following settings are necessary:
•
Select terminal for TP initiator via C1214.
– C1214 = 1 ≙ Te r m i n a l X5 / E1 .
– C1214 = 2 ≙ Te r m i n a l X5 / E2 .
– C1214 = 3 ≙ Te r m i n a l X5 / E3 .
– C1214 = 4 ≙ Terminal X5/E4 (this setting is recommended by LENZE).
•
Select signal of the TP input via C1215/x.
– C1215/x = 0 ≙ LOW-HIGH edge.
– C1215/x = 1 ≙ HIGH-LOW edge
Function procedure
•
Move to the TP signal with homing speed (C1242) towards positive end of travel range limit
switch.
•
The first TP signal determines the reference point.
Modus 9: Traversing direction to negative end of travel range limit switch
Set C1213 = 9.
Function procedure
•
As ”Traversing direction to positive end of travel range limit switch”, but the drive moves
towards the negative end of travel range limit switch.
