1.Because of the highest speed for the digital operation can reach to
400Hz,so when it use in the highest speed place, it can use the speed
limit function limit the output frequency.
2.When the DC braking voltage and the braking time setting too
highly, that may cause the motor overheating.
3.The time for the motor accelerate and decelerate is decided by the
motor rated torque, load torque, load inertia ect.
4.When the antistall (STALL) act in the accelerate and decelerate,
please extend the accelerate and decelerate time. If the accelerate and
decelerate must be very fast, and also the inertia load is very big, the AC
drive can’t speed up or stop the motor in requirement time, that must
install the braking resistance(only can shorten the deceleration time) or
increase the grade of the motor and the AC drive at the same time.

4.When the AC drive is installed in the installation or control panel but
isn’t used, especially in the construction sites or the wet places with lots
of dust, the AC drive should be removed and put in a proper environment
satisfying the storage requirements mentioned above.
5.The electrolytic condenser is easy to degrade with power off for a
long term. Please do not store the electrolytic condenser with power off
for more than one year.
1.4 Considerations for Choices of AC Drives
1.Use large capacity above 600 kva electric current transformer and
capacitor into phase, voltage input side surge current is too large, that
could undermine the input side of ac motor drives. At the moment the
input side must be installed an AC reactor, in addition to reduce the
current, and improve the effect of the input power.
2.To actuate the special ac drive or one ac drive actuate several
motors, the total rated current of the motor 1.25 times can’t exceed the
rated current of the ac motor drive. It is very careful to choose the AC
drive.
3.When the ac motor drive actuate the motor, the startup, the
accelerate and decelerate are limited by the rated current of the AC drive.
The starting torque is small(commercial power directly start 6 times when
start current, when the ac motor drive starting, the starting current can’t
exceed two times),so when the AC drive use for high torque place(For
example Elevator, Blender, Machine tool ect), the AC drive must increase
one or two grade. The optimal way is increasing one grade of the motor
and the AC drive at the same time.
4.To consider that when the AC drive break down and stop the output,
the stop mode for the motor and the mechanical equipment, if they need
sudden stop that must install the mechanical brake.
