The phase currents are shown as a percentage relative to the rated
operational current I
e
. You can monitor each phase (L1/L2/L3)
individually, or the average of all 3 phases.
These measured values can be presented graphically as a bar or line
chart on the display of the 3RW5 HMI High Feature.

You will find further information in chapters Design and operator
controls of the High Feature 3RW5 HMI (Page 111) and Graphic
display of measured values on the 3RW5 HMI High Feature
(Page 156).
Phase currents (rms) The phase currents are displayed in amperes. You can monitor each
phase (L1/L2/L3) individually, or the average of all 3 phases.
These measured values can be presented graphically as a bar or line
chart on the display of the 3RW5 HMI High Feature.

Motor temperature rise Current value of motor temperature rise in %. This measured value is
calculated internally by the 3RW52 soft starter and indicates the
relative temperature rise of the motor.
Remaining motor cooling time Remaining recovery time in seconds still to be observed following
activation of motor protection until the 3RW52 soft starter is once
again ready for operation.
Remaining switching element cooling time 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, installation location, etc.). The remaining
cooling-down period of the switching element is stated in seconds.
Switching element heating The currently calculated switching element heating is continuously
compared with the previously saved switching element heating and
indicated in %.
