Yes, it is possible to Reset consumption in an ATV61/71 drive via Modbus, using RPR register, @: 3120.

It operates little bit differently for ATV61 than ATV71:

ATV71:
Consumption:    APH    @: 3230
Reset:        RPR =    0    [No] (nO)
1    [reset kWh] (APH)
2    [rst. runtime] (rtH)
3    [rst runtime I] (rtHI)
4    [rst. P On t.] (PtH)
64    [Reset all] (ALL)
So, ATV71 consumption reset can be done by RPR = 1

ATV61:
Consumption:    IPHR    @: 3237
Reset:        RPR    0    [No] (nO)
1    [reset kWh] (APH)
2    [rst. runtime] (rtH)
3    [rst runtim I] (rtHI)
4    [rst. P On t.] (PtH)
5    [kW/h Reset] (IPHr)
6    [kW/h Reset] (IPH)
64    [Reset all] (ALL)
So, ATV61 consumption reset can be done by RPR = 5
