Hardware Features – FilteringHardware Features – Filtering

• EMC Filtering– Supplied with all ratings

– Internal Filter allows EN61800-3 Second Environment Levels to be met • Common Mode Filtering

– Common mode cores supplied with all ratings – help attenuate common mode noise– Common mode capacitors supplied with all ratings – provide low impedance path

World Class Motor ProtectionWorld Class Motor Protection

• Reflected Wave issues (also known as Standing Wave or transmission Line Effect) have been well documented in IGBT based drives

• This phenomenon can cause significant voltage peaks at the motor that present the possibility for insulation breakdown

• Rockwell Automation engineers have devoted years of research to develop industry-leading solutions for VTAC Drives– This has resulted in patented Software &

Hardware features that protect motors with long motor leads

– Each pulse is measured and controlled to avoid collisions with other reflected voltage pulses thus minimizing voltage amplification

– These solutions are supported with hundreds of hours of lab tests!

Start Up Icon provides access to Quick Start Utility that allows for fast, easy set-up involving seven parameter groups.

Parameter Icon provides quick access to drive and peripheral component parameters.

Control Source Icon allows control and reference selection.

Diagnostic Icon provides information on faults and alarms.

Display Icon allows operators to configure the OIM for language, monitoring, function keys and other considerations.

Memory Icon allows operators to load and save different parameters sets into the OIM and, subsequently into the drive or to restore factory-set defaults.

Device Select Icon allows operators to identify and select the drive or peripheral device from which to obtain data.

Password Icon provides protection against modifications of all writable parameters by a unauthorized user and selects parameter access levels.

Icons provide users a intuitive interface as well as a logical method of grouping access to drive functions and operations
