FANUC Alarm SVGN-203 — GunA, GunB contact speed is different

FANUC SVGN-203 (“GunA, GunB contact speed is different”): The contact speed used in this Pressure Schedule is different for Gun A and Gun B - but contact speed must match to achieve synchronized contact with the part. First check: Set the contact speed of the Pressure Schedule to the same value for both guns.

Description

The contact speed used in this Pressure Schedule is different for Gun A and Gun B - but contact speed must match to achieve synchronized contact with the part.

Remedy

Set the contact speed of the Pressure Schedule to the same value for both guns. This is done by adjusting the pressure calibration data which determines the contact speed. The Speed at a given Pressure must be the same for both guns. It is recommended to use matching Pressure and Speed values for each calibration point for both guns. Then, find the unique torque% required to achieve the pressure for each gun. OR, just set the contact speed for all points in the Pressure Calibration table for both guns to the same value.
