The reflected wave simulation tool models the high frequency characteristics of the inverter PWM voltage waveform , the cable connecting the drive to the motor and the motor itself, to predict the peak value and rise time of the voltage waveform at the motor terminals. The effect of filters to mitigate the reflected wave phsenomenon can also be simulated. The model does not include effects of cable charging current, which should be considered for low power drives. Consult the Rockwell Automation Wiring and Grounding Guidelines for PWM AC Drives.

The voltage drop calculator estimates the voltage available at the load by computing the voltage drops through the source transformer, cables, line and load reactors, drive and output filters. A plot of available voltage as a function of cable length between drive and motor is generated for the specified tolerance on the source voltage. This tool should be used to appropriately size motor cable for the application.

The harmonics simulator is a circuit simulation program with one or two load branches. Each of the loads can be set to be of a specific type. Waveforms of voltage and current at different points of common coupling are generated along with numerical values for voltage and current THD, and checks for conformance to harmonics standards.

The harmonics calculator is a spreadsheet based tool which uses look-up tables to estimate the voltage and current harmonics at different points of common coupling in a network consisting of multiple loads. Only numerical outputs are provided including checks for conformance to harmonics standards. This tool is more flexible than the harmonics simulator in terms of the load configurations that can be simulated.

The torque harmonics calculator estimates the harmonics in the electromagnetic motor torque for the drive and motor parameters provided by the user. The model does not include the dynamics of the driven load.
