8.4.1.1 Possibilities for the position selection
The following options are available for the selection of different positions:
1. Changeover of profiles
2. Changing the profile position via parameter data (SDO)
3. Changing the profile position via process data (PDO)
• The profile position is defined in [increments] or in the application unit [units].
Possibility 1: Changeover of profiles
A total of 15 profiles is available in the 8400 TopLine.
• A profile describes a motion task that can be converted into a rotary motion by the Motion
Control Kernel in the "Positioning" operating mode.
• A detailed explanation of all profile parameters can be found in the subchapter " Profile entry ".
( 637) of the description of the "Positioning" basic drive function.
• The selection of the profile to be executed can either be executed as a data word via the input
wPosProfileNo or binary coded via the inputs bPosProfileNo_1 ... bPosProfileNo_4.
• The chosen profile is started via the process input bPosExecute of the FB L_MckCtrlInterface or
the control bit "PosExecute" in the MCK control word .

Note!
Setting the machine parameters is a basic prerequisite for the operating modes
" Homing ", " Manual jog " and " Positioning ".
The more precisely the machine parameters are set, the better the results of positioning!
