Determining the address of the spindles (only for 840D sl)

The address of a spindle with Sensor Module SMI24 is defined during commissioning. It depends on the position of the spindle in the SINAMICS topology and on the identifiers used.

You can subsequently determine the address in SINUMERIK Operate.

Determining machine axes of type Spindle

  1. In SINUMERIK Operate, select operating area "Startup"

    The "Machine Configuration" list opens.

  2. Look for the rows whose machine axes are of type Spindle and note down their drive numbers and identifiers.

Check whether Sensor Module SMI24 is connected

  1. Press softkey "Masch. Data" and "Drive Parameters" to show the drive parameters.

  2. Press the "Select Drive" softkey and select the drive that you noted down.

  3. Press the "Search" softkey and enter "p4100" as the search form.

    If parameter "p4100" is found, this means that a SMI24 is connected to the drive that you selected.

  4. If parameter "p4100" is not found, check the parameter of the next spindle.

Determining the address of the SMI24

You can read off the position of the spindle in the SINAMICS topology on the title bar of the drive parameter. The information is displayed as follows:

<number of machine axis>:<name of machine axis>/<identifier of machine axis>

The <identifier of machine axis> comprises

<string>_<bus number>.<slave number>:<DO number>

  1. Note down the "Bus number" and "Slave number" of the spindle.

    In the following example, the "Bus number = 3" and the "Slave number = 3":

  2. In the "SINUMERIK presets" window of the Asset Manager, you require both of these values as well as the drive number from the "Machine Configuration" list.
