Learning Advanced Features
Low leakage PWM uses a 2 phase PWM modulation mode, which helps
minimize degradation and reduces switching loss by approximately 30%.
• Carrier Frequency at Factory Default Settings: 3 kHz
• H100 Series Inverter Derating Standard (Derating): The over load rate represents an
acceptable load amount that exceeds rated load, and is expressed as a ratio based on the
rated load and the duration. The overload capacity on the H100 series inverter is 120%/1
min for normal loads. The current rating differs from the load rating, as it also has an
ambient temperature limit. For derating specifications refer to 11.8 Inverter Continuous
Rated Current Derating on page 569.
• Current rating for ambient temperature at normal load operation.

nd
Motor Operation
The 2
nd
motor operation is used when a single inverter switch operates two motors. Using
the 2
nd
motor operation, a parameter for the 2
nd
motor is set. The 2
nd
motor is operated
when a multi-function terminal input, defined as a 2
nd
motor function, is turned on.
