The PROFIDRIVE standard specifies that PZD1 (ZSW) contains a
status word following the definition in
Table 7-4. The
Programmable Status Word in P41.32 or P41.33 is a collection of
status bits specified by parameters P41.00 to P41.15, or P41.16 to
P41.31. These can be used to set up the status word required by
PROFIDRIVE, and then point P75.30 to P41.32 or P41.33.
Table 8-3 Allocation of the status word bits (Speed control mode)
Bit Meaning
0 Ready for switch-on / not ready for switch-on
1 Ready for operation / not ready for operation
2 Operation enabled / operation inhibited
3 Fault / no fault
4 No OFF 2 / OFF 2
5 No OFF 3 / OFF 3
6 Switch-on inhibit / no switch-on inhibit
7 Warning / no warning

Each location in the PPO sent back to the PROFIBUS master is
specified according to
Table 8-4.
Table 8-4 Transmitted PPO data mapping
PPO Reference Parameter
PZD1 (ZSW) P75.30
PZD2 (HIW) P75.31
PZD3 P75.32
PZD4 P75.33
PZD5 P75.34
PZD6 P75.35
For example, it is decided to monitor 4 parameters, Speed feedback
(P9.01), Current feedback (P9.05), Motor volts (P9.07) and Motor
power (P9.08).
