TE8: Cycle-independent path-synchronous switching signal output
16.2 Functional description
Example:
The following block positions function as switching positions:
• Position X30 for G0-edge change from N10 to N20
• Position X100 for G0-edge change from N30 to N40
Freely programmable velocity threshold value as switching criterion
A freely programmable velocity threshold value is used to define the setpoint velocity
programmed in the part program block at and above which the switching signal is activated/
deactivated.
• If the setpoint velocity programmed in the part program block is above the programmed
threshold, the switching signal is switched off.
• If the setpoint velocity is at or below the threshold value, the switching signal is switched
on.
The edge change marks the programmed end of block position of the previous block as the
switching position.
Example:
The following block positions function as switching positions:
