Description
The system reports that the gun compensation is ready for operation:
• MGDM connected,
• gun number valid
• Parameters for gun compensation valid
• No monitoring Gun compensation has responded
• The system reports in which actual position it is.
• Zero position is closed with gun, without force, with undressed tips and new
shafts, (if "compensation in robot" is parameterized).
• Indicates the sheet thickness of the Weld job selected via the point selection.
(resolution 0.01 mm)
• If an error or a message is present at the PRC7000, the highest priority error
number is output here directly (without mapping).
• Status "0" means no message (no error).
• The geometry wear of the gun, related to the determined reference value for
the geometry test (servo gun parameter Gun stroke for geoemtry test) is
output.
• The value can be positive or negative and is output in two's complement.
• (Resolution 0,01 mm)
• Special, electrode-specific information can be called up via inputs and outputs
of the welding control system using a visualization unit, and electrode
maintenance routines can be triggered.
• An electrode selection is made via the "Electrode number Visu" input.
• The following information associated with the electrode selection is output via
these status outputs (Visu):
"Tip dress request (Visu)"
–
"Prewarning electrode (Visu)"
–
"End of stepper (Visu)".
–
"Start tip dress request (Visu)"
–
"Prewarning stepper dresser blade wear (Visu)"
–
"End of stepper dresser blade wear (Visu)"
–
"Prewarning of gun life (Visu)"
–
"End of gun life (Visu)".
–
• As soon as the outputs have been updated by the control, the electrode
selection is mirrored to the outputs 160-167 "Echo electrode number Visu".
• The status outputs always follow the electrode selection.
• If the status of this electrode changes when the electrode number is statically
• electrode (e.g. due to a welding process), the outputs are updated.
• Nothing changes at the "Echo electrode number Visu" outputs.
• "Timer Ready (Visu)" outputs the mirrored output "Timer Ready".
• If setpoint and actual values belong to an error message, the percentage
deviation of the actual value from the setpoint is output via these outputs.
• For deviations greater than +/- 127%, +/- 127% is output.
• The data format is two's complement.
