YASKAWA iQpump1000 - TEST RUN WITH LOAD CONNECTED

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
iQpump1000 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. There are two sizing methods based on the maximum load applied to the motor. Sizing Method A
provides continuous full power and Sizing Method B may allow the connection of a larger motor compared to Method A, but
the load is limited to 86% motor power, which is often (but not always) adequate for fan and pump loads.

Single-Phase Input Sizing Method A (Continuous Full Power)
Use single-phase input Sizing Method A for applications requiring more than 86% motor 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.
