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
iQpump Micro 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:
• 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.

Single-Phase Input Sizing
The rated output current listed in the tables allows for a 120% overload for 60 seconds. Contact Yaskawa if assistance is needed
in selecting drive models with higher overload requirements. Adding more impedance than is specified will degrade
performance.
