I/O Status Register
These bits indicate the current state of the inputs on the Resolver & Drive I/O module.
Bit: 0
Hex Value:
0001 H
Sug. Var. Name:
RPI@
Range:
N/A
Access:
Read Only
UDC Error Code:
N/A
LED:
RPI on the Resolver & Drive I/O module
Description:
The Run Permissive Input bit reflects the status of the run permissive input signal con-
nected to pin A on the DRIVE I/O connector. When the signal is present, this bit is set. The run per-
missive input signal typically originates from the drive’s coast stop circuitry and is required to turn on
MCR@ (register 101/1 101, bit 1).
Bit:
1
Hex Value: 0002H
Sug. Var. Name:
M_FDBK@
Range:

UDC Error Code:
N/A
LED:
AUX IN1 on the Resolver & Drive I/O module
Description:
The M-contactor Feedback bit reflects the status of the M-contactor feedback input sig-
nal, which is connected to the AUX_IN1 input on the Resolver & Drive l/O module. The status of this
bit will be dependent upon the application. When the input signal is present, this bit is set.
Bit: 2
Hex Value: 0004H
Sug. Var. Name:
AUX_IN2@ or INV_FLT@
Range:
N/A
Access:
Read Only
UDC Error Code:
N/A
LED:
AUX IN2 on the Resolver & Drive I/O module
Description:
The Auxiliary Input 2 bit reflects the status of 115 VAC auxiliary input 2 on the Resolver
& Drive I/O module. When the input signal is present, this bit is on. If an inverting fault breaker is
used, this bit is used to reflect the status of the inverting fault breaker input signal. When the signal is
present, this bit is on.
Bit: 3
Hex Value: 0008H
Sug. Var. Name:
AUX_INS@ or AIR-LOS@
Range:
N/A
Access:
Read Only
UDC Error Code:
N/A
LED:
AUX IN3 on the Resolver & Drive I/O module
Description:
The Auxiliary Input 3 bit reflects status of 115 VAC auxiliary input 3 on the Resolver &
Drive I/O module. When the input signal is present, this bit is on. If Power Module air loss is being
monitored, this bit reflects the status of the Power Module’s air loss signal. An air flow sensor in the
Power Module generates this signal. When the signal is present, this bit is on.
Bit: 4
Hex Value:
001 OH
Sug. Var. Name:
AUX_IN4@ or M_THM@
Range:
N/A
Access:
Read Only
UDC Error Code:
N/A
LED:
AUX IN4 on the Resolver & Drive I/O module
Description:
The Auxiliary Input 4 bit reflects the status of 115 VAC auxiliary input 4 on the Resolver
& Drive l/O module. When the input signal is present, this bit is on. If the motor’s thermal switch is
being monitored, this bit reflects the status of the switch’s signal. When the input signal is present,
this bit is on.
