Input and Output Faults An input or output fault indication can be caused by several wiring fault
conditions during commissioning or normal operation. If an input fault occurs,
check for the following:
• One of the channels is shorted to a 24V DC source.
• One of the channels is shorted to a GND source.
• Two input channels have shorted together.
• One or both output channels have an overcurrent condition.
An input fault can also occur if one of the channels in a dual-channel system
changed state after a 3-second discrepancy time interval, and if the inputs are
configured with one of these settings:
• Dual-channel equivalent 3 s
• Dual-channel complementary 3 s
• Dual-channel SS equivalent 3 s
Fault Codes and Descriptions Faults fall into one of three categories: Stop Category fault, Fault While Stopping
fault, and Safe State fault. Stop Category faults can be Motion faults, Monitor
faults, or I/O faults.
The safety configuration tool can display a fault history queue that provides a
record of the faults detected by the drive. The fault history queue stores the fault
codes and timestamps for the last 10 faults that occurred.
