*) depending on power circuit
Independent of the motor connection (
∆
/ Y) the motor stator resistance is measured
on a warm motor between 2 phases of the motor incoming cable. In this manner the
ohmic line resistance is recorded at the same time (important at long motor cables).

Measuring of motor stator resistance
The maximal value adjustable
in dr.5 depends on the power
circuit. In case the measured
resistance is larger than this
value, the maximal value has to
be adjusted.
