5. PROFIBUii-DP ALARMS
5.1. DESCRIPTION
The alarms indicated to the drive by the Profibus-DP interface card through the Dpram are the following:
1 - Bus loss: if an accidental interruption of the connection occurs, this alarm is generated.
2 - SBI Hardware Fault: if the Profibus-DP interface card is faulted, this alarm is generated.
3 - SBI Ram Fault: this alarm is generated if there is a fault in the Dual-Port-Ram of the Profibus-DP interface card.
The alarm handling carried out by the drive depends on the drive itself and how the alarms are configured.
In case the Master is switched off before the Slave, the Bus-Loss alarm occurs; the drive may handle this event
by avoiding to store the alarm in order not to appear when the drive will be switched on.
The communication between Master and Slave can only be carried out if the initialization of the drive and of the
Profibus-DP interface card is successfully terminated; if not, through the Bus is not possible to determine the
cause of the erroneous initialization.
