Connection of the sensors/limit switches

Touch probe sensor

If a different touch probe source than the one of the current drive is to be used (e.g. a Fast-I/O or any other digital signal), the corresponding touch probe event has to be provided via the ExtTP input ExtTP Touch probe configuration .

Travel range limit switches (hardware limit positions)

The travel range limit switches are provided centrally to the axis data via the two inputs xLimitSwitchPos and xLimitSwitchNeg of the FB L_MC1P_HWLimitSwitchInterface .

  • The two inputs respond to the TRUE status and are to be connected to the corresponding digital inputs to which the limit switches are connected.
  • During a homing mode with limit switch evaluation, monitoring of the corresponding limit switch is deactivated.
  • An active limit switch evaluation in the drive (e.g. Servo Drives 9400 HighLine) is not taken into consideration and can therefore not be combined with a homing mode with limit switch evaluation.
Reference switch

The reference switch is connected to the HomeAbsSwitch input.
