Network and
Comm’s Loss
See Port
Number of
Fault (See
Table 25)
All • DPI network loss
• Communication disconnect at the
serial port
• Check communication adapters and verify connection to the
SMC.
• Reconnect each DPI connected device
Ground Fault 58 Running • Ground fault current level has
exceeded programmed value
• The delay time is too short for the
application
• Check power system and motor; correct if necessary. Check
programmed ground fault levels to match application
requirements
• Extend the delay time to match the application requirements
Line Power
Quality with
Phase Indication
52, 53, 54 Start or
Stop
• Incoming 3-phase voltage
instability or distortion
• High impedance connection
• Check supply voltage for capability to start/stop motor;
check for loose connections on the line side or motor side of
the power wires
• Verify and correct the input power quality
Internal 24V and
System Faults
36, 37 All • Low line condition
• Excessive load on internal 24V
supply
• Check the control power and verify it is within the
specification; check the connections and grounding to the
SMC control terminals
• Replace the control module
