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.

2.2 Conditions for Installation
■ The AC drive shall be installed vertically with screws, and shall not
be installed upside down, obliquely or horizontally on a firm structure.
■When the AC drive is running, it will generate heat. To ensure that
the cooling air path is as shown in figure (b). There is a certain space in
the design, and the heat generated will be emitted upward; therefore, do
not install it under the heat-resistant equipment.
■When the AC drive is running, the temperature of the heat sink will
rise to nearly 90 ℃. Therefor, the mounting surface on the back of the AC
drive must be made of materials that can withstand higher temperature.
EC5000
■When the AC drive is installed in the control panel, ventilation and
heat dissipation shall be considered to ensure that the ambient
temperature of the AC drive does not exceed the specification value. Do
not install the AC drive in the airtight box with poor ventilation and heat
dissipation.
■When installing multiple AC drives in the same control panel, it is
recommended to install them horizontally side by side in order to reduce
the thermal impact on each other. If it has to be installed up and down, the
partition board must be set to reduce the impact of heat generated at the
lower part on the upper part.

■After finishing the wire layout, check the following things:
1. Are all the connections correct?
2. Is there any connection left out?
3. Is there any short circuit or line-to-ground short circuit between the
terminals and the connecting wires?
When the power is on, if the connections need to be changed, first
the power supply should be turned off, and the filter capacitor of the DC
part of the loop will need some time to discharge electricity. The work only
can begin after the completion of electricity discharge. Besides, because
of the residual voltage, sparks may be generated when there is a short
circuit, thus it’s better to conduct the work under voltage-free conditions.
1.Grounding wire must be connected, or electric shock or fire may
happen.
2.The wiring work should be done by the professional technicians.
3.Start the work after confirming that the power is OFF or electric
shock may happen.
Basic Wire Layout Graph
The wires of AC drive can be divided into main loop and control loop.
Users can open the upper cover and see the terminals of main loop and
control loop. Users must lay the wires according to the figure below to
ensure the accuracy of connections.
During the wiring, the selection of the specification of wire diameter
should be in accordance with the standards of electrical engineering for
safety. The screws of the terminals should be tightened, preventing the
sparks caused by loose screws due to vibration. The standard wire layout
figure for EC5000 AC drive is shown below.

are marked explicitly and pay attention to the following instructions
during connection, do not make improper connections.
2.4.1 Basic Wire Layout
■The power supply must be connected with the terminals of the main
loops of AC drive R/L1, S/L2, T/L3. If the power supply is improperly
connected with other terminals, the AC drive will be damaged. Besides,
check whether the voltage/current of the power supply is within the
allowable range indicated on the nameplate.
■The grounding terminals must be grounded well, on the one hand it can
prevent electric shock or fire, and on the other hand it can reduce the
noise interference.
■Connect the terminals with wires, ensure the high reliability of the
connection.

■The connection with analog signal is especially easy to be influenced by
the interference of external noise, thus the wire should be as short as possible
(less than 20m), and shielding wire should be used. The outer wire mesh of the
shielding wire should be basically grounded, but if the inducing noise is very
loud, it is better to connect it to the FC terminal.
■For the need of using contact in this circuit, the double-fork contact
which can process weak signals should be used. Besides, the terminal FC
should not adopt contact control.
■While connecting with the external analog signal follower, sometimes
the interference caused by the analog signal follower or the AC drive will
lead to misoperation, in such conditions, the capacitor and the magnetic core of
ferrite may be connected to the external analog follower, as shown below:

■ While controlling the input of contacts, in order to prevent bad contact,
the contacts that have high reliability for the contact with weak signals should
be used.
Output terminals of transistor(Y3, Y4 )
■The polarity of the external power supply should be correctly connected.
■While connecting the control relay, the surge absorber should be
connected with the two ends of field coil. Please ensure that the polarity is
correctly connected.
■It's best to use the shielding wires as control wires, the isolation network
divested segment before the terminals should not be exposed.
■The wires of control terminals should keep away from the wires of the
main loop, or misoperation may be caused due to noise interference. If an
intersection is needed, make them intersect with a right angle.
■Generally the control wires don't have good insulation. If the insulation
layer is broken due to some reason, high voltage may enter the control circuit
(control panel), leading to circuit damage, equipment accidents or personal
Danger .
■The control wires in the AC drive should be fixed properly to prevent
them from the direct contact with the charge-carrying part of the main circuit
(e.g. the terminal strips of the main circuit).

■The output terminal of AC drive can’t be connected to the inlet phase
capacitor or surge absorber. If the wires are very long, it should be connected
with the AC reactor on the output end.
■There is high frequency current in the extra long wire between
motor and AC drive. This may cause AC drive over flow and stop.
Besides, long wire increase leaking current, this leads to poor precision
of current value. AC drive≤3.7KW choose wire less than 20 meters to
motor, less than 50 meters for AC drive over 3.7 KW. If the wire is very
long a wave filter connected to the output side AC reactor is necessary

■For safety and noise reduction, the grounding terminals of AC drive
should be well grounded.
■The grounding wire of AC drive can’t be grounded together with the
machines with heavy current load e.g. the electric welding machine and
high power motor, they should be grounded separately instead.
■In order to prevent electric shock and fire, the external metal
grounding wires of electric equipment should be wide and short, and
connected to the special grounding terminals of the AC drive system.
■If there is more than one AC motor speed controller connecting
with the ground, Please make sure that is does not form grounding loop,
shown as the following figures:
Grounding terminals of AC drive (EG)
3.1 Check and Test Before Operation
The following matters should be paid attention before the operation:
■Check if wire connection is correct. Confirm AC drive output permInal
U, V, W is not connected to POWER and the ground terminal E(G) is grounded
well.
■Confirm there is no short circuit within every terminal and electricitied
naked part.
■Confirm all terminals connection and joints are tight and not loose
■Ensure that the motor isn't connected with loaded machine.
■Before turning the power on, ensure that all the switches are in the
disconnected state to guarantee that the AC drive won't start or operate
abnormally when the power is on.
■The power supply can only be turned on after the upper cover is
installed.
■It is forbidden to operate the switch with wet hand.
■Display of the keypad panel (no indication of faults)
■The cooling fan installed in the AC drive should work normally.

Operation and inspection
Check whether the acceleration / deceleration are steady.
If there is no abnormality, perform the test run with frequency increased. If
no abnormality happens in the test run above, the formal operation can be
started.
If there is any abnormal phenomena occured, stop AC drive immediately.
Consult “ fault diagnosis” to find the problem. When AC drive stops,
terminal L1/R1, L2/S, L3/T is still with power if main circuit is not
switched off. Any touch onto terminal U, V, W will be shocked. Besides,
wave filter capacitor is still full of charging voltage and need certain period
of time to discharge, if main circuit power is off. Touch inner AC drive circuit
only after power and the DC circuit voltage tested by DC circuit voltage
meter is below safety voltage.
