# How can I measure the amount of energy consumed by the robot in KWh?

- I am using Analyzer on RobotStudio, to monitor the energy used, but at the end of the acquisition, I have only max and min value in Watt. Can I calculate the Total amount of energy used?

- On the graph I had positive and negative values. The negative ones are related to energy recovered?

Thanks

From the RobotStudio operating Manual (check the part in

italics)Total Motor Power

The instantaneous power for a specific joint is positive when it accelerates and negative when it decelerates. If one joint is accelerating at the same time as another joint is decelerating, then the negative energy from the decelerating joint is reused by the accelerating joint. If the sum of the instantaneous power of all joints is negative then the power surplus cannot be reused but it is burned off in the bleeder.Total Motor EnergyPurpose of signalsABB

We get the power consumption via PC SDK API,but we don't know the unit of the figure ,W？KWh？J？,Would you please tell us?

And for the negative power consumption , should it be changed to absolute value and accumulate to the total motor power consumption?
