1) Whether the sound in the motor running abnormal changes

12
2) Whether or not vibration is generated during motor operation
3) Whether the inverter installation environment has changed
4) Whether the inverter cooling fan is working properly
5) Whether the inverter overheating
Daily cleaning:
1) Always keep the drive in a clean state.
2) Effectively remove the dust on the surface of the inverter to prevent dust into the
inverter inside. Especially metal dust.
3) Effectively remove the inverter cooling fan oil.
2.6.2 Regular Maintenance
Please check the place where you are difficult to check. Periodically check items:
1) Check the duct and clean it regularly
2) Check if the screws are loose
3) Check that the inverter is subject to corrosion
4) Check whether the terminal has a trailing mark
5) Main circuit insulation test
Reminder: When measuring the motor insulation resistance with a megger (please use a
DC 500V megger), disconnect the main circuit from the inverter. Do not use insulation
resistance meter to test the control circuit insulation. No need for high voltage test
(factory completed)
2.6.3 Inverter replacement parts
Inverter parts are mainly cooling fan and filter electrolytic capacitors, the life and the
use of the environment and maintenance are closely related. The general life time is:
Device Name
Life Time
Fan
2～3year
Electrolytic capacitor
4～5year
The user can determine the replacement age according to the run time.
1) Cooling fan
Possible cause of damage: bearing wear, leaf aging.
Criteria: fan blades, etc. whether there is cracks, whether the sound when the sound is
abnormal vibration.
2) Filter electrolytic capacitors
Possible causes of damage: Poor input power quality, higher ambient temperature,
frequent load transitions, and electrolyte aging. Criteria: whether the liquid leakage,
safety valve has been protruding, the determination of electrostatic capacitance,
insulation resistance determination.
2.6.4 Storage of the inverter
Users to buy the inverter, the temporary storage and long-term storage must pay attention
to the following:
1) Stored in the original packaging as far as possible into the company's packaging.
2) Prolonged storage will lead to the deterioration of electrolytic capacitors, must ensure

13
that within 2 years through a power, power time of at least 5 hours, the input voltage
must be slowly raised to the rated voltage regulator.
2.7 Guide for Selection of Brake Components
(*): Figure 2-1 is the guide data, the user can choose according to the actual situation of
different resistance and power, (but the resistance must not be less than the
recommended value in the table, the power can be large.) The choice of braking resistor
The actual application of the motor power generation to determine the power, and system
inertia, deceleration time, bit energy load and so have a relationship, the need for
customers according to the actual situation. The greater the inertia of the system, the
shorter the deceleration time required, the more frequent the braking, the greater the
choice of the braking resistor, the smaller the resistance.
2.7.1 The choice of resistance
When braking, the regenerative energy of the motor is almost entirely consumed on the
braking resistor. According to the formula: U * U / R = Pb
Formula U - System Brake Voltage for Stable Braking
(Different systems are not the same, for the 380VAC system generally take 700V)
Pb ---- brake power
2.7.2 Power selection of braking resistor
The braking power is theoretically the same as the brake power, but the derating is 70%.
According to the formula: 0.7 * Pr = Pb * D
Pr - the power of the resistor
D ---- Brake frequency (regeneration process the proportion of the entire process)

3.1 Mechanical Installation
3.1.1 Installation environment:
1) Ambient temperature: The ambient temperature has a great influence on the life of
the inverter. Do not allow the operating temperature of the inverter to exceed the
permissible temperature range (-10 ℃~ 40 ℃).
2) Mount the inverter on the surface of the flame retardant and attach it to the mounting
bracket vertically with screws. Inverter work easy to produce a lot of heat, there should
be enough space around the heat.
3) Please install it where it is not easy to vibrate. Vibration should not be greater than
0.6G. Special attention away from the punch and other equipment.
4) To avoid the place in the direct sunlight, wet, there are drops of water.
5) To avoid installed in the air corrosive, flammable, explosive gas of the place.
6) To avoid the equipment in the oil, dust, dust and more places.
