The currents value may be displayed due to undesirable current while the converter in the power regeneration mode is during power driving.
This is not a fault.

The power supply frequency is monitored.
The motor thermal cumulative value displayed as a percentage with 100

7
The input power to the converter is monitored.
The counter of cumulative power calculated from the input power monitor

value is displayed.
Use Pr.46 to clear the counter.
The counter of cumulative energization time since the converter shipment is
displayed.

The number of times a cumulative value has reached the maximum value of
65535 hours can be checked with Pr.47.
The values of input power during regenerative driving is displayed with signed
numbers on the operation panel. The monitoring on the parameter unit or via
10
communication does not support the display of the values with signed
numbers (the absolute values are displayed).
The ON/OFF status of I/O terminals on the multifunction regeneration
25
converter is displayed. The parameter unit does not support this display.
The electricity cost calculated from the electricity rate (cost per kWh) set in
28
Pr.896 and the cumulative energy is displayed.
