the motor always has the optimum voltage. in the oil industry F eature fit ote Sinusoidal output voltage No additional stress the motor insulation: non-VSD compliant motors can be used, motor reli­ ability and lifetime are maximized. Usually the motor fan is the biggest noise source with sine filter solutions. AP programming, advanced IR- compensation and flux control The effects load changes motor voltage can be compensated i. Standard distribution transformer can be used step-up solutions. High starting torque is available with special transformer design. The filter suppresses the high frequency com ponents the output voltage. there are restrictions to motor cable length.e. Filters are available IP00 degree protection over the hole power range.7.g. EX applications ■ Submersible pumps with long motor cables e.e. ACS800-04 frame size R6 pow range, filters are available also with IP23 enclosure class. Scalar control is required with sine filters. Alter Main features ■ Optimized design that takes into account ■ switching frequency, voltage drop and filtering char­ acteristics ■ Proven technology ABB has delivered hundreds of sine filter solutions over the last years ■ Cost effective solution ■ Standard software has all the parameters that need to set This means that the output voltage waveform almost sinusoidal without high voltage peaks.g. medium voltage motor needs driven ■ Step-down applications ■ There are industry specific requirements for peak voltage level and voltage rise time ■ Motor noise needs reduced ■ Maximum safety and reliability needed e. there are a num ber parallel motors ■ Step-up applications e. Allows the use of transformers the drive output match any required motor voltage.2009 .g. The ABB sine filter solution can used variety of applications: ■ Motor does not have adequate insulation for VSD duty ■ Total motor cable length long e. Less motor noise. Voltage drop at motor cable can be compen-sated with transformer i.g. 40 Hardware options FE68404592 REV 3.Sine filters ABB sine filter solution The ACS800 sine filter solution ACS800 industrial drive equipped with sine filter. enjoys most the premium features the standard ACS800 industrial drive
