E. Operate the motor speed after power on to verify the validity
of the motor rotation direction and then to slowly increase the motor speed.
F. Motor start or stop must be controlled by drive control signal instead of switching
the power on/off. The lifetime of the drive will be significantly reduced if the invalid
operation using the switch control of the power is applied to motor control.
G. Because the starting current of motor is 6~8 times of rated current, Do NOT install
the magnetic contactor between the drive and motor for the motor operation.
H. When using the single-phase power source to drive the three-phase drive (not the
standard type of single-phase power input), first confirm the horsepower of motor,
and then calculate the motor rated current by multiplying the motor rated current
by 2 to gain the drive rated current. The drive selection for this single-phase
power must have the rated current equal to the calculated drive rated value.
Formula: Motor rated current × 2 = drive rated output current
Example:
a. Drive selection:
Motor specification: 220VAC, 1HP ; rated current: 3.1A
Drive rated current=3.1 (A) × 2 = 6.2 (A)
Drive specifications: 230VAC, 1HP drive = 4.2A(continuous current)
2HP drive = 8A(continuous current)
 Select 2HP drive for 1HP AC motor.
