A.4 Drive Derating Data
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.
u
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.
n 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.

Temperature Derating
As the ambient temperature for the drive is increased above the drive specification the drive should be derated. Additionally
parameter L8-35 Installation Method Selection on page 315 should be set according to enclosure type and mounting method as illustrated in Figure A.1
.
n Output Current Derating Due to Ambient Temperature
Set L8-12 and L8-35 according to the installation conditions when the ambient temperature is above the drive specification
or when drives are mounted side-by-side in a cabinet. The output current is derated as shown in Figure A.1
