A.4 Drive Derating Data
The drive can be operated at above the rated temperature, altitude, and default carrier frequency by derating the drive capacity.

Single-Phase Derating

P1000 drives are compatible for use with both three-phase and single-phase input power supplies. The drive output to the
motor is always three-phase, regardless of number of input phases.
Output capacity to the motor is derated when using single-phase input power and the drive firmware includes protection for
single-phase input applications. This protection is enabled by default. Disabling this protection for single-phase input
applications can void warranty and result in premature failure.
Selection of larger models always results in greater output capacity to the motor when supplying the drive with three-phase
input power. However, the selection of larger models does not always yield greater output capacity when using the drive 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.
n Single-Phase Input Sizing (Continuous Full Power)
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.
Note: Adding more impedance than is specified will degrade performance.
Service Factor
When using a service factor greater than 1.15, multiply the nominal power (HP) by the service factor (SF), then select a drive
with a higher power rating than the product of that equation.
Example: 1.5 HP x 1.3 SF = 1.95 SF HP
The user should select a 2 HP or larger drive.
