Dedicated I/O protection is supported by the Dedicated Input Protect parameter (7108). It selects
the dedicated I/O used with air-cooled 6SR4_0 or water-cooled 6SR325 for any cell type. The
parameter "Drive Has Input Breaker" (7127) must also be set to "yes". All input protection is
handled independent of the SOP.
For drives other than air-cooled 6SR4_0 or water-cooled 6SR325, the parameter Dedicated Input
Protect (7018) can be used to enable the same protection if the inputs and outputs are wired
correctly. The SOP flags that would normally be associated with these inputs and outputs are
disabled, and have no effect when the associated cells are selected.
This parameter can only enable, and cannot disable pre-assigned cell types currently hard-
coded. The fall-back for all cell types, if the parameter is not set, is to use SOP flags.
NOTICE
If this parameter is not used for HV-AP cell types, then all associated cell protection SOP flags
must be added to the SOP Input Protection logic to ensure that the drive has the required
protection.
In fall-back mode, the SOP is responsible for acting on protection detection SOP flags,and in
opening the input MV breaker. The SOP for these cases, must contain all the logic to properly
utilize the protection flags and assert the proper I/O to remove the connection to the MV supply
in a timely manner.
The following inputs and outputs are dedicated to input protection:
TB1-51 C
TB1-53 NC
TB1-55 NO
IDO_9
IDO_14
IDO_15
DI-3E
Refer to Section User Inputs and Outputs in Chapter Hardware Interface Description, for
descriptions of the internal I/O. If the dedicated feature is turned on, the associated SOP flags are
no longer connected.
System Arc Fault
This feature allows external detection circuitry to inform the control that an arc fault occurred
and to remove MV power. The drive is then aware of the external event, and will log it in the fault
