Process data handling in case of error

If the inverter receives invalid process data, the inverter uses the process data received last
(valid). You can optionally set that the contents of the process data in the inverter are set to
the value "0" after invalid process data has been received.
The setting in 0x24E5:001 is independent of the response selected in
0x2859:005 if invalid process data has been received!
If the application requires that the drive keeps moving with the last valid proc-
ess data when receiving invalid process data, set the response "No response" or
"Warning" in 0x2859:005. Moreover, the selection "Clear data [1]" must not be
set in 0x24E5:001. Deleting the process data would stop the motor.

9.3 Acyclic data exchange
The acyclic data exchange is normally used for transmitting parameter data the transmission
of which is not time-critical. Such parameter data are for example operating parameters,
motor data, and diagnostic information.
Details
The acyclic data exchange enables access to all parameters of the inverter.
•
For all communication protocols except Modbus, the parameter is addressed directly via
•
the index and subindex.
The parameter attribute list contains a list of all inverter parameters. This list in particular
•
includes some information that is relevant to the reading and writing of parameters via the
network.

Info
Bit coded display of the status of parameter access monitoring.
1 ≡ parameter access monitoring is active.
1 ≡ within the time-out time set in
parameter write access to the "keep-alive register"
(P595.02) was made.
Time after which the WLAN network with the current settings of the
WLAN parameters is restarted if no "keep alive" messages are received.
• 0 s = function deactivated (no WLAN restart).
• With a setting > 0 s and a time-out, the control units sets
"Restart with current values [1]".
Info
Selection which process data the inverter is to use after receiving invalid
process data.
The last valid process data of the master are used.
The contents of the process data in the inverter is set to the value "0".
