In the “Automatic operating mode”, the PLC specifies the process image of the outputs. Page – Data Set – Technology Parameters 4: Page Only set the breakaway pulse when it is really required e.
Normally, fuseless mounting combination of motor starter protector and soft starter is sufficient. Selecting Display Settings Activity moni- Parameter deactivated toring time set 3 30 s Specifying The Coasting Method Commissioning 6.

Reference quantity depends on motor used, but in any case lower than the 3RW44 53 – 3RW44 Entering The Motor Data The motor current of the connected drive should be set to ensure proper functioning of the soft starter during starting and stopping, as well as in regard to motor protection.
Connecting the generator directly in the supersynchronous 3tw44 may cause soft starter faults.
Up to 9 channel-related diagnostics messages are possible see also station status 3, bit 7. Page 50 refer to “Restoring the factory settings” on Page The operating hours counter is activated as soon as control voltage is applied.
This ensures that enough acceleration torque is generated throughout the motor run-up phase. If the drive is not operating under rated service conditions after the specified interval has expired, the startup procedure is interrupted and a fault message is generated. Note The rated output of the 3RW44 to be configured must be at least as high as the sum of the motor’s rated outputs. Statistics The firmware product version is listed on the front of the device below the petrol- colored labeling field.
Problems That Can Occur Commissioning 6. Stopping time Motor braking Stop command torque at soft starter Figure Page 20 – Configuration instructions Page 21 – Startup class Page 22 – Application examples for normal starting Page Switch on the supply voltage. Typical circuit diagrams The remaining entries are moved up one entry. Slow Speed Function The torque generated in the motor can be influenced with the slow speed torque. Page [A] Data format: Page 17 Motor speed Soft start voltage ramp Soft start torque-controlled Load e.
Channel-based diagnosis not available 1: Page 29 – Installation, Connection and Branch Layo Page Page – Current Limiting in Combination with the Introduction From this version onwards, DPV1 operation read, write data set and alarms is also possible downstream from a Y link. Specifying The Manula Of The Protective Functions The ground fault function is only active after completion of run up, 3rw4 during starting.
Soft Starter With Contactor Disconnector main Contactor Include a tripping delay of 1 s for the main conductor or control the main conductor via an output 3ra44 parameterized “On-time” function as described in circuit diagram 9.
Parallel Starting Of 3 Motors The rated output of the 3RW44 to be configured must be at least as high as the sum of the motor rated outputs. Intrinsic Device Protection Note If the soft starter is switched off via a motor protection or inherent device protection tripping, the action cannot be acknowledged 3rrw44 the “Trip Reset” function until the displayed cooling time has expired.

The level change from 0 to 24 V DC is evaluated manua, the input. Parameters Parameter assignment active Alarm bit is updated continually. If a start command is output during the stopping procedure, this procedure is aborted and the motor is started up again using the specified starting mode.
Page 76 ATEX requirements are met. The value is incremented by 1 manjal time the output is set. Page – 3RW44 in a standard circuit with soft st The motor is switched off due to a ground fault. Special semiconductor fuses, e.
Siemens Sirius 3RW44 – 315kW Soft Start with 230V controls
Note If the “DC braking” function is selected, the “DC braking contactor” function must be assigned to one output of the soft starter.
Page 91 The “Trip Reset” input is edge-controlled.
Page 50 – Switching on for the first time Page 51 – Quick start menu, when switching on for Setting Slow Speed Parameters Upper current limit The upper current limit can be used to determine increased power loss in the application, for example caused by bearing damage.
