Touch Sensor Status Fast Output - Kemppi A7 350 Integration Manual

3.12 Touch sensor status fast output

This welding system is equipped with an instantly
responding touch-sensing feature for locating the work-
piece in teaching of the welding robot.
In normal operation, the status of the touch sensor is
passed to the robot via a fieldbus connection. However,
fieldbus bus latency affects the efficiency of operation. To
avoid delays, the hardware-based fast output can be used
for better response. For connection of fast status output,
the robot must have at least one hardware input available.
Connect the fast output to the touch sensor fast status
output connector on the rear of the robot interface unit by
using a custom cable. Connect the other end of the cable
to the hardware input of the robot controller.

The fast output requires an external 18–36 V power
supply.
The output is galvanically isolated from other
hardware and is short-circuit-protected. The maximum
continuous switching current is 100 mA @ +24 V.
