Setting range Explanation
• IL1 The phase currents are displayed as a per‐
centage. You can monitor each phase (L1 /
• IL2
L2 / L3) individually, or the average of all 3
• IL3
phases.
• Average
These measured values can be presented
graphically as a bar or line chart on the dis‐
play of the 3RW5 HMI High Feature.
You will find further information in chap‐
ters Design and operator controls of
the 3RW5 HMI High Feature (Page 116)
and Graphic display of measured values on
the 3RW5 HMI High Feature (Page 116).

Remaining recovery time in seconds still to
be observed following activation of motor
protection until the 3RW51 soft starter is
once again ready for operation.
The remaining cooling-down period of the
switching element depends on the thermal
capacity of the power unit and the ambient
conditions (temperature, air circulation, in‐
stallation location, etc.). The remaining
cooling-down period of the switching ele‐
ment is stated in seconds.
The currently calculated switching ele‐
ment heating is continuously compared
with the previously saved switching ele‐
ment heating and indicated in %.
