(3) Fault Display
When the VS-686SS5 detects a fault, the fault is displayed on the digital operator and activate
the fault contact output and the motor coasts to a stop. Refer to Table 31 for the fault and the
display at fault occurrence.
Since the VS-686SS5 stores the information obtained at fault occurrence in the inverter, the
information can be verified. For details, refer to Table A-4.
[Example]
Verifying the status at fault occurrence (speed reference, motor speed, output current in the
example) and resetting the fault when overcurrent occurs during operation at 50% speed.
