New spot selection
Program start
Bosch Rexroth AG | Electric Drives and Controls
 Program start
Both parts use a handshake.
The robot initially selects a new spot number at the corresponding timer inputs.
Afterwards, it sets the "New spot selection" input.
This input requests the timer to read out the new spot number, to prepare the
corresponding welding program and to set the program-dependent and electrode
dependent timer outputs accordingly. If the timer found the spot in the internal
spot table or if a program was directly selected (0...255), the timer will set the
output "Spot selection taken over".
If no valid spot number has been specified, the base pressure of program 0 will
be output.
Once the robot has detected the "Spot selection taken over" output, it can
evaluate the corresponding outputs of the weld timer. Furthermore, it must reset
the "New spot selection" input.
As a response, the timer will reset the output "Spot selection taken over".
The actual program start is initiated by the input "Program Start" of the robot. At
the end of the schedule, the timer will either set the "Weld complete" output, if the
schedule was o.k., or the "Welding fault" output will be set if the schedule was not
o.k., or the "Timer ready" output will be reset if a general fault was present.
When the robot resets the "Program Start" input, the timer will reset the "Weld
complete" output. The fault has to be corrected and reset in the event of an
incorrect schedule.
If the spot number selected during start differs from the one specified together
with the program selection function, the welding sequence will not be started.
Spot numbers lower than 256 will be interpreted as program numbers by the
timer.

KSR selection

When calling up welding programs with electrode nos. 1 through 9, output KSR
selection 1 is simultaneously activated. When calling up welding programs with
electrode nos. 10 through 19, output KSR selection 2 is simultaneously activated.
When calling up welding programs with electrode nos. 20 through 29, output KSR
selection 3 is simultaneously activated. For all other electrode numbers, the KSR
selection outputs are not changed.
7.1.3

Electrode maintainance

Die The electrode status outputs correspond to the status of the electrode that
has been assigned to the welding program that was activated by spot selection.
