(1) A lower motor supply voltage can be used. This will result in a reduction of output power.
(2) Specification for 20kHz PWM switching frequency .
(3) Specification for 10kHz PWM switching frequency .
(4) The XC6-480 drive must be connected only to a grounded wye-source where the maximum voltage does not exceed 277
VAC to ground.
(5) Motor output current is specified as a peak value (not RMS) and corresponds to the maximum phase current during a
locked rotor condition.
1.1.1. System Power Requirements
The following equations can be used to determine total system power requirements. The actual
power required from the mains supply will be the combination of actual motor power (work), motor
resistance losses, and efficiency losses in the power electronics or power transformer.
Use an EfficiencyFactor of approximately 90% in the following equations.
