Homing with TouchProbe (TP) or zero−pulse (MP)
The reference point is at the next TouchProbe signal, or zero−pulse plus the reference point offset.
·
Mode 8 ( byHomingMode = 8):
– Move to the home position in CW rotation.
– Home position offset dnRefOffset is entered as positive.
·
Mode 9 ( byHomingMode = 9):
– Move to the home position in CCW rotation.
– Enter the reference point offset dnRefOffset or zero−pulse as a negative value.
Take care that the TP has been parameterized in the system block!
Example: Mode 8 with a 9300 Servo PLC through MCTRL_MotorControl

In Parameter Manager: byHomingMode = 8
·
C0911=0, homing to zero−pulse or
C0911=1, homing to TouchProbe (terminal X5/E4).
·
With C0911=1, C0912 can be used to select whether a rising or falling edge will trigger a
TouchProbe.
(C0912 = 0: rising edge; C0912 = 1: falling edge)
·
With C0910 a delay can be set for a TP/MP.
