600 Interlock fault C,S
Occurs when digital input 1 on the
Computer Card stops receiving 24
VDC.
Verify that the 24 VDC power supply is
functioning. If not, check the fuse supplying
its input power.
Verify that 24VDC is present across
terminals I/O4 and I/O3 on the breakout
board for the Computer Card IO.
If no devices are installed in the E-stop loop,
verify the yellow jumper wire is installed
between terminals 29 and 31, and that 24
VDC is present on terminal 31.
If there are devices in the E-stop loop, verify
that they are all closed.

Inverter Digital Input 4
fault
D
Occurs when Inverter Digital Input #4
Function (IO-03) is set to “External
Fault High”, and 120 VAC is applied to
Digital Input 4 on the Remote IO.
Occurs when
Inverter Digital Input #4
Function (IO-03) is set to “External
Fault Low”, and 120 VAC is removed
from Digital Input 4 on the Remote IO.
Verify the control wiring supplied to Inverter
Digital Input 4 on the Remote IO, broken out
to terminal 87 on the terminal block.
View the Inverter I/O Status screen on the
HMI. Verify that the indicator for Inverter DI 4
on the screen toggles as the 120 VAC going
into Inverter Digital Input 4 toggles. If not,
replace the digital input module in the
Remote IO block.
605
Inverter Digital Input 5
fault
D
Occurs when Inverter Digital Input #5
Function (IO-04) is set to “External
Fault High” and 120 VAC is applied to
Digital Input 5 on the Remote IO.
Occurs when
Inverter Digital Input #5
Function (IO-04) is set to “External
Fault Low” and 120 VAC is removed
from Digital Input 5 on the Remote IO.
Verify the control wiring supplied to Inverter
Digital Input 5 on the Remote IO, broken out
to terminal 88 on the terminal block.
View the Inverter I/O Status screen on the
HMI. Verify that the indicator for Inverter DI 5
on the screen toggles as the 120 VAC going
into Inverter Digital Input 5 toggles. If not,
replace the digital input module in the
Remote IO block.
606
Inverter Digital Input 6
fault
D
Occurs when Inverter Digital Input #6
Function (IO-05) is set to “External
Fault High” and 120 VAC is applied to
Digital Input 6 on the Remote IO.
Occurs when
Inverter Digital Input #6
Function (IO-05) is set to “External
Fault Low” and 120 VAC is removed
from Digital Input 6 on the Remote IO.
Verify the control wiring supplied to Inverter
Digital Input 6 on the Remote IO, broken out
to terminal 89 on the terminal block.
View the Inverter I/O Status screen on the
HMI. Verify that the indicator for Inverter DI 6
on the screen toggles as the 120 VAC going
into Inverter Digital Input 6 toggles. If not,
replace the digital input module in the
Remote IO block.
607
Inverter Digital Input 7
fault
D
Occurs when Inverter Digital Input #7
Function (IO-06) is set to “External
Fault High” and 120 VAC is applied to
Digital Input 7 on the Remote IO.
Occurs when
Inverter Digital Input #7
Function (IO-06) is set to “External
Fault Low” and 120 VAC is removed
from Digital Input 7 on the Remote IO.
Verify the control wiring supplied to Inverter
Digital Input 7 on the Remote IO, broken out
to terminal 90 on the terminal block.
View the Inverter I/O Status screen on the
HMI. Verify that the indicator for Inverter DI 7
on the screen toggles as the 120 VAC going
into Inverter Digital Input 7 toggles. If not,
replace the digital input module in the
Remote IO block.
