AxisData Machine parameters
• For accepting the machine parameters of the drive/motor, connect this input
with the output DI_AxisData of the SB LS_DriveInterface.
• The machine parameters of a master drive can be displayed with the
FB L_SdSetAxisData . In this case, the FB output AxisData must be connected to
this input. ( 510)
