Inthe majority of applications this will give satisfactory performance, however, in a smallnumber of applications output filtering is strongly recommended to improve systemfunctionality, reliability and lifetime.These applications include:• High capacitance motor cables• Long motor cables, up to 300 m• Multiple motors connected in parallel• Motors without inverter grade insulationA range of high quality output chokes are available for <strong>MOVITRAC</strong> ® <strong>LT</strong> E with thefollowing key features:• Limits output voltage gradient• Limits transient over voltages at motor terminals, typically
