cooling equipment in an electrical room. Use this formula to calculate the approximate
power loss of the drive in nominal conditions.
P
loss
[kW] = P
mot
[kW] x 0.025
It is possible that there will be an increase of 0-0.5% in the power loss when you have options
in the cabinet. Some options, for example output filters and input devices, cause more power
losses.
To calculate the power loss, use the ecoSmart tool. See www.danfoss.com.
