Maximum locked rotor current of the motor. This setting defines
the current limit which is maximum current for the motor to
draw in locked rotor situation (starting or stalled). If the
measured current exceeds this setting limit it is considered to
be overcurrent fault and corresponding measures can be
applied to disconnect the feeder and motor from the supply.

(Im>; 51M)
The motor's maximum overload current. Exceeding this setting
stalls the motor. This setting defines when the thermal replica
switches to the short (stall) time constant. As long as the
current stays below this setting value, the motor should
run even when overloaded.
