Parameter Settings for PowerFlex Drives Using Sine-wave Filters, dV/dt Filters, and Adjustable Voltage Application Technique

2022-05-24
●About This Document:
■This document applies to PowerFlex® 753, 755, and 700 AC Drives.
■This document provides information about key parameters that can be adjusted when applying Adjustable Voltage Control, a type of Volts per Hertz (VHz) Control, through a filter at the output of a variable-frequency drive (VFD). Information is provided for the following types of output filters:
▲Sine-wave filter
▲Derivative of voltage with respect to time (dV/dt) filters including:
◆Inductor, and resistor (LR) dV/dt filter
◆Inductor, resistor, and capacitor (LRC) dV/dt filter
■The drive parameter settings that are described in this document can be used to:
▲Modify stability gains.
▲Modify modulation mode.
▲Help prevent over reaction to the charging current into the capacitor branch of a sine-wave filter
