TE470/TE480
S.p.A.
TOTAL STEPS
This parameter indicates how many segments are to be created for implementing the stepper curve.
When it is set to zero, the stepper function is disabled.
SPOTS 1
This parameter indicates the number of spots that make up the relevant segment. The stepper function is
deactivated when this parameter is set to zero.
When TOTAL STEPS = 1 and SPOTS 1
≠
0, the value set in the SPOTS 1 parameter is equal to the number of
welding maximum spots.
INCREMENT 1
This parameter indicates the increase percentage of the current to be reached at the end of the spots set in
parameter SPOTS 1. The stepper function is deactivated when this parameter is set to zero.
SPOTS 2, 3, 4...7
These parameters indicate the number of spots of which the relevant segments are made up.
INCREMENT 2, 3, 4...7
These parameters indicate the current increase percentage to be attained at the end of the spots set in the
relevant segments.
SPOTS DRESS.
The SPOTS DRESS. parameter indicates the number of spots required at each electrodes dressing.
The following message appears on reaching the spot number set on the control unit:
SPOTS FINISHED
DRESS ELECTRODES
that is cleared by pressing a key. Then the control unit, without resetting the spots-counter, resumes the welding
cycle until it will have again carried out the spots set in this parameter.
FIRST INSERT
The FIRST INSERT parameter indicates the first insertion delay. This function permits optimizing the balance of
machine line absorption.
After having selected this parameter, in order to change it you must first press the WELD/NO WELD button.
Then the value can be adjusted from 1 to 99 using buttons
and
. Since this adjustment is performed by the
welder manufacturer, the user need not change this value.
For more information refer to the specific chapter.
STOP SPOTS
The STOP SPOTS parameter permits programming the control unit so that it stops when welds are carried out
with current values beyond the limits set in the weld program. The programmed value indicates the consecutive
number of "out of limits" welds that cause the machine to stop.
The limits error occurs when a weld is carried out with values higher or lower than the limits set in parameters
CURR. MIN and CURR. MAX, or ANGLE MIN and ANGLE MAX. Adjust this value using buttons
and
from
0 to 9. Since the function is disabled when this value is set to zero, the welder will never stop if pre-set limits are
exceeded.
For further information, please, check the relevant paragraph.
HANDLE
With this parameter, the user determines the number or type of handles connected on the TE470/TE480.
There are 3 different choices:
1
a handle was connected to connector XS10 with the switch for the external calling of 2
programmes.
2
two handles were connected, one to XS10 and the other to XS11.
4PRG
a handle was connected to connector XS10 with the commutator for the external calling of 4
programmes.
For the description of this function, please refer to the relevant chapter ("HANDLES DESCRIPTION").
