Fault Display
When detecting a fault, the VS
−
616G5 displays the fault contents on the digital operator and
activates fault contact output, the motor coasts to a stop. For the display at fault occurrence
or troubleshooting, refer to Table 31 ”Fault Diagnosis and Corrective Actions”. Since the
VS
−
616G5 stores the information obtained at fault occurrence in the inverter, the information
can be verified. For details, refer to Table A
−
3 ”Monitor Constants List”.
( Example )
Verifying the status at fault occurrence and resetting the fault when overcurrent occurs during
operation at 60.00 Hz.

By resetting the fault, the
display entered just prior to the
fault occurrence is returned.
Fault reset cannot be activated while forward/reverse run signal from control circuit terminal
is ON. Turn OFF the signal and check the safety of the sorrounding area, then reset the invert-
er.
