5 Description of the Functions
5.5 SIMODRIVE POSMO A functions
Response for
P701 = 0
(factory default)
5-198
S
The drive LED indicates when PZD data is being actively substituted
((P701 = 1 and STW.10 = 0).
In this case, the LED flashes, alternating between yellow/green.
If STW.10 = 1, then the behavior of the LED is compatible to the
behavior with P701 = 0.
S
The function cannot be used in the standalone mode (refer to
P100).
S
Independent of the operating mode and independent of P701, pa-
rameters P967 and P972 always display the PZD data presently
being internally used in the drive.
This can used, when establishing a connection to the drive, after
bus failure or replacing the master, to immediately send the last
valid control word (for which STW.10 = 1), the last valid block selec-
tion and start byte (or speed setpoint) to the drive. This means that
the connection can be immediately restored without changing the
status of the drive.
The drive behavior is compatible to previous software releases.
PZD data is always evaluated independently of STW.10.
