Single-Phase Derating
A1000 and P1000 drives are optimized and compatible for use with both three-phase and single-phase input power
supplies. The output to the motor is fixed at three-phase.
Output capacity to the motor is reduced or derated when single-phase input power is used.
Selection of larger models always results in greater output capacity to the motor when the drive supplied with three-phase
input power. Conversely, selection of larger models does not always yield greater output capacity when the drive used
with single-phase input power.
Several factors affect the amount of derated drive output capacity when single-phase input power is supplied to the drive,
such as:
• single-phase input voltage level
• motor voltage rating
• amount of input impedance
The tables in this section assist in model selection by considering factors that affect the amount of derating in single-phase
input power applications.
The Output Capacity-Motor FLA listed in the tables allows for a 120% overload for 60 seconds.
Contact Yaskawa if assistance is needed in selecting drive models for heavy duty/single-phase applications with higher
overload requirements.
