Interface

Bit 1: Diag.Stat_Diag
If the MOVIDRIVE
®
drive inverter sets this bit, the DP master must pick up diagnostic data until
this bit is cleared again.
Bit 0: Diag.Prm_Req
This bit is set by the MOVIDRIVE
®
drive inverter if it needs to be parameterized and configured
again. This bit remains set until the drive inverter has been parameterized with
DDLM_Set_Prm.
3.4.3 Data in Octet 3: Station Status 3
Fig. 21 shows the coding of octet Station Status 3 in accordance with DIN E 19245 Part 3. In sta-
tion status 3 only bit 7 is relevant at the moment. Bits 0-6 are reserved.

Fig. 21: Coding of the octet Station Status 3 to DIN E 19245 Part 3
The individual bits have the following meaning in accordance with DIN E 19245 Part 3:
Bit 7: Diag.Ext_Diag_Overflow
If this bit is set more diagnostic information is present than specified in Ext_Diag_Data. This
bit is generally set at zero by the MOVIDRIVE
®
drive inverter.
Bits 6-0: Reserved
3.4.4 DP Master Address in Octet 4
In this octet the address of the DP master is entered, by which the MOVIDRIVE
®
drive inverter was
parameterized with the DP service DDLM_Set_Prm. If the drive inverter was not parameterized by
a DP master, this octet contains the address FFhex.
3.4.5 Ident Number in Octet 5/6
The manufacturer identification for the DP slave type is allocated by the PROFIBUS User Group.
This Ident Number can be used both for checking purposes and for exact unit identification. The
MOVIDRIVE
®
drive inverter enters the Ident Number 6000hex in this octet, the more significant
part (60hex) is entered in octet 5, the less significant part (00hex) is entered in octet 6 of the Ident
Number.
3.4.6 Unit-related Diagnosis using Octet 7/8
The MOVIDRIVE
®
drive inverter supports unit-related diagnosis. Unit-related diagnostic informa-
tion is only available when the drive inverter outputs a fault message or warning. By setting bit 3
Diag.Ext_Diag in octet 1 Station Status 1, the drive inverter indicates to the master that unit-related
diagnostic information is available. The unit-related diagnostic information is stored in octet 7 and
more specifically in octet 8. As the header of the unit-related diagnostic data, octet 7 contains the
length of the unit-related diagnostics (incl. header byte). As the fault code is normally returned as
external diagnostic information in one byte, octet 7 normally contains the value 02hex (length 2
bytes) and octet 8 contains the fault code from the drive inverter.
