1.3 Cautions in utilization
1. The general motor running at a low speed decreases its lifelime for the
heat dissipation effect is quite bad. If low speed running needs to last
for a long time, the frequency inverter special-purpose motor should be
chosen or the load should be lightened.
2. When using the frequency inverter, the temperature of motor is a little
5
higher comparing to the power frequency operation. It is normal phenomena.
3. In application of AC60 series frequency inverter, you have to confirm
all machine insulation to prevent damage to the equipment. Moreover, when
the motor working in tough environment, please periodic inspect the
electrical insulation to ensure the safety of the system work.
4. If the motor adapter is not consistent with frequency inverter's rating
current ( The rating current of the motor is far smaller than that of
frequency inverter), please adjust the protective value to ensure safe
running.
5. In occasions such as load raising, usually there is negative torque and
frequency inverter breaks off for over-current or over-voltagte. In this
case, you should consider to choose matching brake unit.
6. Frequency inverter, in a certain output frequency range, can meet the
load equipment’mechanical resonance. To avoid it, you can set up jumping
frequency.
7. As output voltage of the inverter is pulse-wave type, if there is capacity
which can improve power factor or pressure-sensitive resistance which used
for thunder-proof in the voltage output side, the frequency inverter will
break off or its parts will be damaged, so it is necessary to dismantle
them. Moreover, it is proposed not install switch parts like air switch
and contactor (if it is necessary to install switch on output side, please
make sure the output electricity of frequency inverter is zero when the
switche is working)
8. At over 1,000 meters altitude, the inverter’s heat dissipation function
worsened due to the thin air, it is necessary to derate use.
9. The inverter output voltage is pulse wave type. If use digital multimeter
measurement, deviation of the reading will be great. And the deviation is
different by using different type of digital multimeter. Under normal
circumstances, while RMS 380V, digital multimeter reading is around 450V.

terminal and grounding terminal.
4. In order to minimize the impact of electromagnetic interference, when
the electromagnetic contactors and relays is very close to inverter,
you should consider the installation of surge absorption device.
5. When the peripheral equipment(filter 、 reactor)of inverter are
installed, the first step is use the 1,000 volts MΩ megger to measure
the grounding insulation resistance to ensure it not less than 4 MΩ.
6. Can not install the progressive phase capacitance and
resistor-capacitor absorbing device in the frequency inverter U, V, W
output terminal because the frequency inverter’ voltage output is PWM
pulse wave. If there is capacity which can improve power factor or
pressure-sensitive resistance which used for thunder-proof in the
voltage output side, the frequency inverter will break off or its parts
will be damaged, so it is necessary to dismantle them.
7. In order to reduce the leakage current of the earth, the motor cables
should be as short as possible. When the carrier frequency is less than
3KHz, the largest distance between frequency inverter and motor should
be less than 50 meters; When the carrier frequency is greater than 4KHz,
you should appropriately reduce this distance; In order to restrain
23
interference of the frequency inverter output side to the other equipment,
you have better to install a special noise filter at the output side of
the frequency inverter and lay the output cables through the metal tubes.
8. If the frequency inverter need to frequently start, do not cut off the
power, you should operate it through the control terminals (COM / F W D.
REV) or keyboard.
9. As analog signals are very easily to be interfered, isolation device
or shield lines are needed for the external control wires of the
inverter and the ground terminals of shield lines are needed to be
connected to the metal closet(ground terminals) of the inverter.
10. Control cables、power cables should be separated from the motor cables.
Generally there should be a sufficient distance between them,
especially between the parallel cables that extend for long distance;
When signal cables have to pass through the power cables, they should
be orthogonal crossing.
11. Main circuit wiring and wire diameter specifications have to be in
accordance with national laws.
12. Pls switch motor or switch power after inverter stop output.
13. While dismantle or change motor, you must cut off the input power of
inverter.
14. In order to avoid accidents, ground terminal E or 〨 must be reliable
grounding (grounding impedance should below 10 Ω). Otherwise there is
a risk of leakage current. For frequency inverter ground point, you
should best adopt the special ground pole. You can also use the share
ground pole, but never use tandem ground line.
15.Pls do not change three phase frequency inverter input into two phase.
Otherwise there may be malfunction. If you have only two-phase power,
please choose single-phase power frequency inverter.
16.The frequency inverter can't be used in the occasions where voltage of
24
power grid excesses the enable input voltage. If the power grid voltage
excesses the inverter voltage limit, please supply power to frequency
inverter with transformer.
17. The wire length between the frequency inverter and the braking unit
should not exceed five meters; The wire length between braking unit and
braking resistance should not exceed 5 meters.
18.If the frequency inverter output terminals drive inductive loads, such
as electromagnetic relays, contactors, etc., surge voltage absorption
circuit should be added, such as RC absorption circuit(be careful that
the leakage current should be lower than the control electromagnetic
relays or contactor' hold current),pressure-sensitive resistance or
freewheel diode(be used in DC electromagnetism circuit, but the polarity
of the freewheel must be paid attention to).The absorption circuit
components must be as close to the relays or winding of the contactor
as possible; Shown as below:
