2.2 Transport
This product is a precise device, please handle it with care during the
transport, prevent it from severe collision.
2.3 Storage
This product must be in the packing box before installation. If it won’t
be used for a period, in order to keep it within the warranty of our company
and for the future maintenance, the following matters must be paid attention
to for the storage:
√
The product must be put in a dust-free and dry place.
√
The temperature of the storage place must be -20
℃～
+60
℃
.
√
The relative humidity of the storage place must be 0%
～
95% without frost.
√
Avoid putting the product in an environment with corrosive gas or liquid.
√
It is better to put the product on a shelf or stand with a proper package.
Notice!
1. Even if the humidity meets the requirements of the criterion, if the
temperature changes quickly, moisture condensation or icing may also
happen, thus the product should not be stored in such place.
2. Do not put the product directly on the ground, but on a proper stand.
If the surrounding environment is very bad, desiccant should be put in
the packing bag.
3. When the storage period is longer than 3 months, the surrounding tem-
perature should not exceed 30
℃
, because the electrolytic condenser
is stored with power off, and it will easily degrade if the tempera-
ture is high.
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 pla-
ces 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.
2.4 Considerations for choices of AC drives
1.Use large capacity above 600 kva electric current transformer and capa-
citor into phase, voltage input side surge current is too large, that could
undermine the input side of AC 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 curr-
ent of the AC drive. It is very careful to choose the AC drive.
3.When the AC 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 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.
2.5 Note for parameter setting
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.
