Voltage drop at the motor cable Δ U
cable
The voltage drop of the motor cable depends on the motor current and the cross sec-
tion, length and material of the cable. The voltage drop can be read from the following
table.

INFORMATION
The voltage drop at the cable is compensated by the IxR compensation.
SEW‑EURODRIVE frequency inverters adjust this value in the "Automatic calibration
ON" mode every time the frequency inverter is started. In order to provide for a
voltage reserve in the frequency inverter for this compensation, you have to take into
account the voltage loss via the motor cable.
