Object "PA_SELECT" (see page 73)
Using the object "PA_SELECT", the PAD assignment can be changed during operation:
Sub-index
Meaning
value
dec
hex
1
PAD length (not variable)
6
0x06
2
Object index assigned for PAD1 (3)

Object sub-index assigned for PAD1 (3)

Object index assigned for PAD2 (4)

After changing the PAD - assignment via object "PA_SELECT", PA_ENABLE is set to "0" to avoid an undefined
condition. After a PAD change the PAD's must be manually enabled again using the PA_ENABLE object.
So that this setting of the PAD channel is already available upon power-up, the corresponding COMPAX parameters (P139 ...
P142) resp. PAD_INI are to be assigned as follows:
Sub-index
Meaning
value
(Parameter)
dec
hex
1 (P139)
Object index and sub-index assigned for PAD1 (3)
6322688
0x607a00
2 (P140)
Object index and sub-index assigned for PAD2 (4)
0
0x000000
3 (P141)
Object index and sub-index assigned for PAD3 (5)
0
0x000000
4 (P142)
Object index and sub-index assigned for PAD5 (7)
6286336
0x5fec00
3 The PAD numbers in brackets are valid for a PD length of 8 bytes (P196 Bit 0...2 = "4").
