The t is defined as:

Sine-wave filter
When there is longer cable length connected between motor drive and motor, the damping will
lead to high frequency resonator, and make
This phenomenon will generate twice-input voltage in motor side, which will easily make motor voltage
overshoot to damage insulation.
To prevent this phenomenon, installing sine-wave filter can transform PWM output voltage to
smooth and low-ripple sin wave, and motor cable length can longer than 1000 meters.
Installation
Sine-wave filter is serially connected between motor drive UVW output side and motor, which is
shown as below:
