Output frequency This value is displayed only if the starting and
stopping output frequencies differ from the
Motor temperature rise Current value of motor temperature rise in %.
This value is recorded by means of sensors
and shows the relative temperature rise of the
Remaining time for motor overload protection The remaining time for tripping the motor
overload protection provides a dynamic
prediction of the time remaining until the
tripping of the motor overload protection,
depending on the momentary motor current.
Remaining motor cooling time The remaining recovery time after protective
tripping of the motor until the soft starter is
Remaining switching element cooling time The remaining cooling time of the switching
element is dependent on the thermal capacity
of the power unit and the ambient conditions
(temperature, air circulation, installation
Switching element heating The currently calculated switching element
heating is continuously compared with the
previously saved switching element heating.
Remaining switching frequency monitoring time For more information, see Chapter Switching
frequency monitoring (Page 122).
Monitoring the process image of the 3RW55 soft starter with the 3RW5 HMI
High Feature
Operating principle
The process image inputs (PII) contains current information about the soft starter and
processing state. The process image outputs (PIQ) contains the current control commands
to the soft starter. The control command states of the control source, which has control
priority according to the operating mode controller, are entered in the data memory of the
process image outputs.
● You are in menu "Monitoring > Process image".
In the process image input (PII) and output (PIQ), you can see which bits of the process
image are active or inactive.
