3-26 SB3000 Drive Configuration and Programming
I/O Status Register (Continued) 201/1201
115 VAC Auxiliary Input 5 Bit 5
The Auxiliary Input 5 bit reflects the status of
the 115 VAC auxiliary input 2 on the
Resolver & Drive I/O module in the
Rectifier’s PMI rack. When the input signal
is present, this bit is set. Hex Value: 0020H
Sug. Var. Name: AUX_IN5@
Access: Read only
UDC Error Code: N/A
LED: AUX IN5 on
Resolver module
Pre-Charge Feedback Bit 12
The Pre-charge Feedback bit reflects the
status of the Rectifier’s pre-charge
contactor. The PMI sets this bit when the
contactor is closed. Hex Value: 1000H
Sug. Var. Name: CHG_FB@
Access: Read only
UDC Error Code: N/A
LED: N/A
This bit must be used by the inverter application tasks. The load inverters must not
be allowed to operate if the Rectifier’s pre-charge contactor is open.
Drive Fault Register 202/1202
The bits in the Drive Fault register indicate the cause of a Rectifier shutdown. The bits in this register are
latched until they are reset by setting the Fault Reset bit of the Drive Control register (100/1100, bit 8). After
turning the Fault Reset bit on, the Rectifier may be re-started after turning the desired command bit in
register 100/1100 off and then back on again. If the fault condition still exists, the identifying bit in this register
will immediately be set again.
The fault conditions reported in this register result only in the Rectifier shutting down. The UDC task is not
stopped automatically if a Rectifier fault occurs unless it is specifically instructed to in an application task.
The user must ensure that the AutoMax application task tests register 202/1202 and takes appropriate action
if a fault occurs.
Note that the status of this register is also reported in the error log for the task in which the error occurred.
Most faults reported in this register are also indicated by the EXT FLT or P.M. FLT LEDs on the Rectifier’s
PMI Processor.
DC Bus Overvoltage Fault Bit 0
The DC Bus Overvoltage Fault bit is set if
hardware detects that DC bus voltage
exceeds the maximum of 900 volts. Hex Value: 0001H
Sug. Var. Name: FLT_OV@
Access: Read only
UDC Error Code: 1018
LED: P.M. FLT
