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.
