Motor parameters
Operating principle
On the 3RW55 and 3RW55 Failsafe soft starters, you can set the motor parameters "Rated
operational current I
e
", "Service factor", "Rated torque", "Rated operating speed" and "Motor
connection type". Setting of the rated operational current I
e
is the minimum requirement for
operation. The motor parameters are located on the rating plate of the three-phase induction
motor being used. You will find a description of all other parameters in chapter Functions
(Page 129).
Setting options
• 3RW5 HMI High Feature
Menu: "Parameters > Soft Starter > Parameter set 1 / 2 / 3 > Motor parameters"
Access protection to the 3RW5 HMI High Feature is not active or has been reset.
• With SIRIUS Soft Starter ES (TIA Portal) via the local interface on the 3RW5 HMI High Feature
Brief overview: Window "Project Navigation" with current project under created Soft Starter
> "Parameters" > Window "Work area" >"Soft Starter > Parameter set 1 / 2 / 3 > Motor
parameters"
• With a fieldbus via a 3RW5 communication module:
– With SIRIUS Soft Starter ES (TIA Portal) Premium / Professional (only via a 3RW5 PROFINET
or PROFIBUS communication module)
Brief overview: See SIRIUS Soft Starter ES (TIA Portal) via the local interface on the
3RW5 HMI High Feature
– Configuration software of the control system (e.g. STEP 7 with corresponding HSP)
– User program
You can find additional information on the parameters that can be set via the fieldbus in the
manual of the respective 3RW5 communication module.
