This particularly applies if the motor protection has tripped. For details of fuse and circuit breaker assignment, refer to chapter Feeder component layout standard circuit Page and chapter Feeder component layout inside-delta circuit Page The maximum torque that can be generated depends on the selected slow speed.

Page 47 – Changing Parameters: In the case of increased operating sequences, the 3RW44 should be dimensioned at least one capacity level higher than the highest connected motor output. If a start command is issued during the stop process, the process is interrupted and the motor is started again with the set startup mode.

Operation of the soft starter produces waste heat power loss refer to Chapter 10 “General Technical Data”. Specifying Current Limit Values Page “Fieldbus” menu, the parameters set on the soft starter will be overwritten with the values stored in the GSD file or in the OM when the bus is started.

Page 65 Commissioning 6. Page mm 6. Inherent Protection If the soft starter is switched off via a motor protection or device protection tripping, the action cannot be acknowledged using the “Trip reset” function until the displayed cooling time has expired. Bit Diagnostics Data that is transferred from the soft starter and indicates the current operating status, e.

Asymmetry detected Asymmetry is present, alarm bit is updated continually. In the case of pumps, for example, a breakaway pulse often leads to misfiring.

The following GSD files are available: The measured maximum and minimum phase current in bridging mode is stored for each phase. The dynamic braking torque determines the braking effect at the start of the braking process to reduce the speed of the motor.
