ROBOTIC INTERFACE

2.17 DUAL PROCEDURE SWITCH COM- MAND

This is an active low output from the robot con- troller used to activate the dual procedure switch. When the Power Wave is running a dual proce- dure overlay this output is used to switch between procedures. If the output is held high by the robot controller then procedure A is active, and if the output is held low then procedure B is active.

2.18 WIRE STICK DETECT

This is a resistance measuring input to the robot controller used to detect a wire stick. The intended use for this resistance check is to mea- sure the resistance between the output terminals of the weld equipment. This is not directly possi- ble with a Power Wave because the resistance between the output studs is always 40 Ohms or less. Additional circuits have been added to allow the wire stick detect to work properly although it is not directly measuring the resis- tance between the output studs. If a resistance of approximately 100 Ohms or less is found then a wire stick error is reported by the robot con- troller.

3.INTERFACE CIRCUIT DESCRIP- TIONS

CAUTION

All of the signals between the Power Wave and the robot controller were designed to operate in a shielded cable. No surge or high frequency protection has been added to the circuitry.
