Case distinction

Prerequisite: The "420: Touchprobe positioning – absolute target position" application mode is activated.

Case 1: Touchprobe not activated (TP PO 0:0)

If the "Start" signal (PO 1:7) is canceled during travel to the target, the drive is stopped and continues to travel to the setpoint position (PO 7, PO 8) when this signal is set again.

Case 2: Touchprobe activated (TP PO 1:0), no trigger detected (TP PI 1:2)

If the "Start" signal (PO 1:7) is canceled during travel to the target, the drive is stopped and continues to travel to the setpoint position (PO 7, PO 8) when this signal is set again. When the setpoint position is reached, the feedback "No trigger detected" (TP PI 1:2) is set.

Case 3: Touchprobe activated (TP PO 1:0), trigger active (TP PI 1:1)

If the "Start" signal (PO 1:7) is canceled during travel to the target, the drive is stopped and continues to travel to the setpoint position (PO 7, PO 8) when this signal is set again. When the trigger has occurred, the new target position results from the actual position at the trigger time (recorded value) and the specified relative position (TP PO 3, PO 4). The value of the relative position (TP PO 3, PO 4) is added if the direction of travel is positive and subtracted if the direction of travel is negative. The acknowledgment "Trigger active" (TP PI 1:1) is set.
