PZD: Process data
Note:
The number of valid words in P1788:0 and P1789:0 depends on the selected PPO type.
Invalid words (are contained in parameters with an index greater than the number) have
the value 0.
Example:
P1788:0 = 2
2 words are valid, i.e. it involves either a PPO1 or PPO3 P1788:1
contains the process data 1 (PZD1) P1788:2
contains the process data 2 (PZD2)
P1788:3 to P1788:10 have the value 0
An overview of the process data in the speed–controlled mode and in the positioning mode
is included in Chapter 5.6.1.
