1 Spot Welding Application Using a Motor Gun
1.11 Tip Dressing Instruction (SVDRESMOV Instruction)
1-109
TIP DRESS COND. Window
1. DRESS LENGTH
(CURRENT, TOLERANCE, SETTING(OUT#))
Current length for dressing operation is indicated.
Tolerance range for this operation: 0.00 to 9.99 mm
– Condition to ON the signal
Current value < Tolerance range
– Condition to OFF the signal
Current value
>= Tolerance range
2. DRESS TIME (CURRENT, TOLERANCE, SETTING(OUT#))
Current dressing time is indicated.
Tolerance range for this operation: 0.00 to 9.99 sec
– Condition to ON the signal
Current value
> Tolerance range
– Condition to OFF the signal
Current value
=< Tolerance range
3. STARTING TORQUE (CURRENT, TOLERANCE, SETTING
(OUT#))
An absolute data for servo dresser average torque, which is measured
between 100 msec and 300 msec after the rotation is started, is indi-
cated.
Tolerance range for this operation: 0 to 300%
In case pressure is applied no later than 300 msec after the rotation is
started, “0” is indicated to {CURRENT} of {STARTING TORQUE}. Also,
at this time, the universal signal will not be controlled.
– Condition to ON the signal
Current value < Tolerance range (minimum value) or Current value>
Tolerance range (maximum value)
– Condition to OFF the signal
Tolerance range (minimum value)
=< Current value =< Tolerance
range (maximum value)
