input. When using frequency other than 60 Hz, the input frequency should be further examined
by the drive's manufacturer. The voltage for single-phase input power supply should be 220 V
with -10 5% tolerance to motor's maximum voltage. A tolerance of -10

between standard products and three-phase power input, so pay extra attention when entering
tolerance values if you apply single-phase for drives. Because single-phase input average DC
bus voltage is lower than the equivalent three-phase input, the maximum output voltage (motor
voltage) will be lower than the single-phase input.
The input voltage should not be lower than 228V
is generated for motors. Thus, if motor torque at basic speed under full-load is required, maintain
input voltage in a stable status. If you need to obtain the rated horsepower, you can try to use
more transformers.
You can use Table A.2-1 to help select applicable drives for 220V
reactor sets the standard for limiting the DC bus ripple and improves the input power factors of
all models. For single-phase power input, the more DC bus ripple, the larger the drive's overload
capacity. Therefore, it is necessary to fully understand the overload requirements of all
applications. Before using single-phase applications, you must obtain relevant data from the
motor's nameplate such as horsepower (HP) and full-load amperage (FLA).The drive you use
should meet or exceed the HP and FLA requirements listed on the motor's nameplate.
