Description
1.3 Operating principle
Functions
● Soft starting with parameterizable starting voltage and starting ramp time
● Soft stopping with parameterizable ramp-down time
● Parameterizable current limiting function
● Soft torque for smooth ramp-up and ramp-down (avoiding torque peaks by means of
torque limitation)
● Integrated motor overload protection with adjustable trip class (Class 10A, 10E, 20E,
Class OFF)
● The intrinsic device protection protects the 3RW51 soft starter against overload
● Ramp-up detection
● Extended operating and diagnostic functions is provided by the optional 3RW5 HMI
Standard or 3RW5 HMI High Feature
● Connection to motor in inline circuit or inside-delta circuit
● Adjustable RESET MODE (manual RESET, remote RESET, auto RESET) for the
functions of motor protection
● Analog output for output of a measured value
● Optional 3RW5 communication module for integration into bus systems
● Firmware updates upgrade the firmware of the respective device
Further details can be found in Chapter Functions (Page 83).
