5.142 L_SdSwitchPoint - position switch points
This FB serves to implement up to 8 simple position switch points (cams). When the current drive
position is inside a range defined via parameters, the output assigned to this "switching area" is set
to TRUE.
• The output setting does not depend on whether the switching range is approached by the posi-
tive or negative side.
• In the modulo measuring system (rotary table) the switching ranges can also be defined beyond
the 0° position (e.g. switching on at 350° and off at 10° in CW rotation).

Input for accepting the current position
• Connect this input with the position signal to be accepted. Depending on the ap-
plication, this can be a setpoint or an actual position.
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)
