Power source (does not apply to ARCITEC)
When using PIB to control the power source with an analogue reference (Flexible
Mode) the reference characteristics are determined by the parameters:
ProcEquipRefConv (gain), ProcEquipRefOffset (offset) and
ProcEquipMaxRef.(Max 48 V DC):
When replacing PIB or the power source the weld result can deviate from previous
result depending on the tolerances in the analogue circuits in PIB and the power
source
.
By adjusting one or both of the two first-mentioned parameters above it is possible
to eliminate the difference and avoid comprehensive modification to the weld
program.
If a power source has no base voltage (reference is linear from 0 V) for example,
LAF and others, the gain is adjusted by ProcEquipRefConv.
On a power source that has base voltage (output voltage at ref. 0V) for example,
RPA and others, adjustment of both parameters is necessary. With several
iterations where Offset is adjusted at the lowest current weld value and the gain is
adjusted at the highest current weld value, the weld result is trimmed to acceptable
similarity to the result before the replacement.
The adjustment is appropriately made in small increments.
For example, if the welding voltage is assessed to be 5% too low, the configuration
value is reduced by a value that is < 5%, if the welding voltage is too high, the
configuration value is increased by < 5%, etc. Note - inverted conditions.
The procedure is repeated until the desired result is achieved.
The procedure is suitable if similarity between several power sources is required.
It is recommended that changes are noted for the PIB or the power source that have
caused the change if the standard configuration is not used.
