VTF Series Drive Output Filters
Extend the life of your motors and cables by reducing the harmful effects of voltage spikes caused by voltage wave reflection. Voltage wave reflection is a function of the voltage rise time (dv/dt) and the length of the motor cables.
AutomationDirect VTF series drive output filters protect motors and cables by combining a patented dampening circuit with a low pass filter to increase the voltage rise time (dt out of dv/dt), thereby preventing voltage spikes from exceeding 1,000V.
The impedance values on each end of the cable run don't match, causing voltage pulses to be reflected back in the direction from which it arrived. As these reflected waves encounter other waves, their values add, causing higher peak voltage. As wire length or carrier frequency increases, the overshoot peak voltage also increases.
Peak voltages on a 480V system can reach 1,600V, and 2,100V on a 600V system. These high peak voltages can cause a rapid breakdown of motor insulation, leading to motor failure.

* LR-4250 & LR-4300 have dual-connector lugs, and will require multiple conductors per phase of the appropriate size to fit the lugs.
Properly sized and applied, the manufacturer guarantees that the VTF will limit motor terminal peak input voltage to 150% of the bus voltage with a wire lead length of 1,000 feet and a carrier frequency of 4 kHz. Maximum lead length and carrier frequency can vary depending on wire lead type. If a properly selected, installed, and loaded VTF filter fails to meet the guaranteed performance levels, the manufacturer will provide the necessary components or replacement filter at no additional charge. The manufacturer does not take responsibility for additional installation or removal costs, to include, but not limited to, replacement of third-party equipment.
Minimum System Requirements for Guarantee - In order to achieve the performance levels as stated in this guarantee, the electrical system must adhere to the following: The VTF must be sized at no more than 110% of the drive output current rating. If the load has a potential for overhauling, the drive must be equipped with braking resistors or other features limiting bus voltage to no more than the level of the peak line voltage. The VTF must be wired no more than 10 feet from the drive.
