Bit 7: Diag.Deactivated
The frequency inverter as DP slave sets this bit permanently at zero.
This bit is set by the DP master if the MOVITRAC
®
31.. frequency 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 frequency inverter as soon as it has received the Sync command.
Bit 4: Diag.Freeze_Mode
This bit is set by the frequency inverter as soon as it has received the Freeze command.
Bit 3 : Diag.WD_On
This bit is set by the MOVITRAC
®
31.. frequency inverter if the watchdog control is on.
Bit 2:
This bit is permanently set to one by the MOVITRAC
®
31.. frequency inverter.
Bit 1: Diag.Stat_Diag
If the MOVITRAC
®
31.. frequency 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 MOVITRAC
®
31.. frequency inverter if it needs to be parameterized and
configured again. This bit remains set until the frequency inverter has been parameterized with
DDLM_Set_Prm.
