8.2.4.1 Weld Program Parameters
The iPAK2v2 control has 256 weld programs. As Table 52 shows, Parameters of weld program 0 through 255 are mapped
to addresses (Hexadecimal number)
16#0000 – 3FFF
. Each weld program (schedule) includes 64 words data. Weld
program 0 starts at address
16#0000
and ends at address
16#003F
, then each subsequent schedule uses the next 64
words addresses, with last schedule using address
16#3FC0-3FFF
. The address offset of each parameter in the weld
programs can be found in Table 52 .
Based on the above description, the following equation (Equation 1 ) is used to calculate a parameter’s address:
Equation 1:
Parameter’s address =
Start address (0000) + [Weld program number x 64] + Parameter
address offset in Weld program
For example, to obtain the address of Main current of weld program 5, calculation will be:
Start address =
0000
Weld program number =
5
Main current address offset in schedule =
12
Address of Main current of Weld program 5 =
0000 + [5x64] + 12
=
332 (Hexadecimal
number address is 16#014C)
