Clean Motor Output Wave
As a result of the five-
level PWM control, the
output current waveform
is close to a sine wave.
Harmonic currents in
the motor windings are
minimized so the heat
loss is negligible and
there is very little torque
ripple on the output shaft.

U-phase Current at 100% Speed
Protective Functions Include:
• Inverter overcurrent
• Inverter overvoltage
• Low system voltage
• Motor ground fault
• Motor overload
• Cooling fan abnormal
• Over-temperature
• CPU error
• Water cooling alarm

• Power factor control for synchronous motors
Output Voltage Modulation
The output switching modulation strategy is dynamically
adjusted based on three speed zones to minimize motor
torque pulsation.
