68/128
If the control unit is in seam weld mode with autoretain deactivated, its activation implies the
automatic deactivation of the seam weld mode and automatic commutation of the unit to
SPOT mode.
START 1-2 NC
When this parameter is set to ON it enables the normally closed inputs of the cycle start
signals. This allows the starting of the welding cycle only in the presence of the double
exchange contact, normally open that closes and normally closed that opens.
When set to OFF, the control unit ignores the status of the two signals and the starting of the
welding only depends on the status of the NO inputs.
If set to RIC 7-8, the two NO inputs become program recalls from a functional point of view so
as to extend the number of recallable programs directly through the inputs.
BIC 1-2 NC
When this parameter is set to ON it enables the normally closed inputs of the cycle start
signals. This allows the starting of the welding cycle only in the presence of the double
exchange contact, normally open that closes and normally closed that opens.
When set to OFF, the control unit ignores the status of the two signals and the starting of the
welding only depends on the status of the NO inputs.
If set to RIC 5-6, the two NO inputs become program recalls so as to extend the number of
recallable programs directly through the inputs.
SEAM WELD MODE
This parameter is used to enable the function that adapts the control unit to seam welder
specifications. The activation of the seam weld mode automatically deactivates the autoretain.
Further information is supplied in the
SEAM WELD MODE
paragraph.
CASCADE MODE
This parameter allows reversing the output signal of the end cycle (END), that is to say from
normally open contact to normally closed contact, to allow putting more control units in
cascade.
Check the proper paragraph for further information.
WELD – NO WELD
When the optional board code 50200 is installed, this parameter allows the operator to select
the priority of the weld-no-weld control.
When the parameter is set to INT, the running of the external WELD-NO WELD line is
deactivated whilst the button on the TE700 control unit remains enabled.
When the parameter is set to EXT, the running of the external WELD-NO WELD line on board
code 50200 is active whilst the button on the front panel of the TE700 control unit is disabled.
When the parameter is set to BOTH, both WELD-NO WELD controls are enabled: the one on
the TE700 front panel and the external control line on the board code 50200. The two controls
are in series therefore to switch the unit to NO WELD mode, simply set only one of the two
controls to NO WELD mode whilst in order to switch the unit to WELD mode both controls
must be switched to WELD mode.
DSP UPG PRESS
If key <+> is pressed when this parameter is selected, the operator can remotely activate the
software upgrade procedure inside the inverter unit. The spot welder must not be off during
the upgrade procedure. Any other operation during the upgrade procedure is prohibited and
welds may not be carried out. In order to resume the running of the spot welder after the
upgrade procedure, it must be turned off and then back on again once the procedure is
finished.
