Interface
Bit 1: Diag.Station_Not_Ready
This bit is set by the MOVIDRIVE
®
drive inverter as DP slave if the drive inverter is not ready
for data exchange yet.
Bit 0: Diag.Station_Non_Existent
The drive inverter as DP slave sets this bit permanently at zero. This bit is set by the DP master
if the MOVIDRIVE
®
drive inverter cannot be accessed via the bus. If this bit is set, the diagno-
stic bits in the master contain the status of the last diagnostic message of the drive inverter or
the initial value.
3.4.2 Data in Octet 2: Station Status 2
Fig. 20 shows the coding of octet Station Status 2 in accordance with DIN E 19245 Part 3. Station
status 2 comprises information which is generated either by the master or the DP slave itself. The
bits which are controlled by the master are generally set at zero by the DP slave. In the following
the individual status bits will be discussed in greater detail.

Fig. 20: Coding of the octet Station Status 2 to DIN E 19245 Part 3
The individual bits have the following meaning in accordance with DIN E 19245 Part 3:
Bit 7: Diag.Deactivated
The drive inverter as DP slave sets this bit permanently at zero.
This bit is set by the DP master if the MOVIDRIVE
®
drive inverter was identified as non-active
in the DP slave parameter set and taken off the cyclic processing.
Bit 6: Reserved
Bit 5: Diag.Sync_Mode
This bit is set by the drive inverter as soon as it has received the Sync command.
Bit 4: Diag.Freeze_Mode
This bit is set by the drive inverter as soon as it has received the Freeze command.
Bit 3: Diag.WD_On
This bit is set by the MOVIDRIVE
®
drive inverter if the watchdog timer is on.
Bit 2:
This bit is permanently set at one by the MOVIDRIVE
®
drive inverter.
