Use our helpful filters to sort by specific family or search by amps, control voltage, or horsepower at 230V or 460V. This is enough power to operate a 230 kva motor during soft start. We have two identical pumps, motors and soft starters and both shut down in this way. With its innovative torque control system, it can be used for drives with a power output up to 710 kW at 400 V — respectively 950 hp at 460 V — in an inline circuit or up to 1200 kW at 400 V — respectively 1700 hp at 460 V — in an inside-delta circuit. When all spaces are filled, the first entry is overwritten. The station address of the soft starters is pre-set to 126 as the factory default.
This overwrites all settings made up until that point. The soft start in control cabinets can be implemented in almost any application in a simple and practical way with our complete soft starter range. The motor is mounted and connected to a floating pump chain drive. The loads should have similar mass moments of inertia and torque curves. Caution Risk of damage to property. Please suggest me some measures so that my motor runs continuously even after the soft start. Set the station address for the soft starter to 3 or higher.
Siemens support was stumped remotely though, they didn't actually visit. Certainly we as installers or end users are responsible for supplying specified conditions, but I was very surprised this particular sequence was possible at all. The set values depend on the particular application and must be optimized during commissioning. During writing, the value entered is ignored, as the baud rate is always automatically detected by the soft starter. I expect Bentov's solution is far cheaper. You might also be able to just connect some kind of voltage recorder, and then read the result after a starting sequence or two.
Strangely, the one pump did start perfectly and run once for 30 minutes. You might be able to simply adjust your generator's main output voltage downward a bit to solve this problem. I am new to this type. The soft start message says it registered high voltage to the soft starter unit. This may not be sufficient to sustain the inrush current. Or did they only discuss parameters? They represent the compact and price-attractive alternative to start-delta starters.
As always, I am tempted to say. A wrongly set breakaway pulse, e. We've had a lot of trouble with this, always on the high side, with Siemens soft starters supplied by fluctuating utility power. Remedy: Check the motor and the soft starter dimensioning. You can choose the correct protection Class and parameters according to.
Thanks to its innovative control method, it is not just the only 2-phase-controlled soft starter in the world for use in the power range up to 250 kW at 400V — respectively 300 hp at 460V — because of its especially compact design, it ensures a space-saving, clear layout in the control cabinet. Then they set me up with communications software to monitor the unit, plus I hooked up my own datalogger, etc. That unit would ramp up, reach speed, then have a quiet moment no sound from the starter , followed by thumping closure of the bypass contactor and a corresponding current spike that tripped the main circuit breaker. We are a new shrimp farm in Saudi Arabia and with no pump there is no farm. As an all-rounder, it covers all drive types. The signal bit is updated continuously.
Setpoints and actual values can be traced and displayed in the and frequency domains. Siemens has failed to provide a solution. I have attached a sketch of the autotransformer setup we use, cheap thing to try as a permanent fix if the separate control deal works. Personal data Surname, first name:. We make our motor soft starters have all kinds of protection functions to protect the safety of the soft starter and the motor.
Rated current soft starter 2. Be careful with how you do it! In our neighborhood, the utility tends to jack up voltage in anticipation of heavy irrigation pump loads, not unusual to see mains pushing 515 when pumps are off. There could be some internal fault in the unit, or it could have been incorrectly installed follow the manual , such that there is no driving voltage for the coil of a bypass contactor. As soon as the starter fails, the voltage will go from just a few volts, to the full line voltage, and you will always have the full phase voltage on the one side of your meter, so let a professional carry it out for you, with all the safety precautions activated. .
