MWHrs
Displays the total energy the drive has consumed or produced. Calculated from the absolute magnitude of the
product of motor speed and motor torque (power), accumulated over time. This value will increase in both regen
and motoring modes of operation. This parameter value can be changed (written to) by the user.
