The t
r
is defined as:
When there is longer cable length connected between motor drive and motor, the damping will
lead to high frequency resonator, and make impedance matching poor to enlarge the voltage reflection.
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:
