ACD320 User Manual

1.2 Use range

(1) This inverter is only suitable for three phases AC asynchronous motor in general
industrial field.
(2) When apply inverter to such equipments that arerelated much to the life, great
property, safety devices etc., please must handle cautiously and consult producer.
(3) This inverter belongs to the control device of general industrial motor, if used in
dangerous equipments, must consider the security safeguard procedures when the inverter
breaks down.

1.3 Use notice points

(1) ACD280 series inverter is voltage-type inverter, so temperature, noise and vibration
slightly increasing compared to power source running when using, belongs to normal
phenomenon.
(2) If need to run for a long time with constant torque of low-speed, must select motor
of frequency conversion. To use general asynchronous AC motor when running at a low
speed should control temperature of the motor or carry on heat dissipation measure forcedly,
so as not to burn the generator.
(3) Such mechanical devices such as gearbox and gear wheel need lubrication. After
running at a low speed for a long time, may be damaged because the lubrication result
become poor, so please take necessary measures in advance.
(4) When the motor running with frequency above specified, besides considering the
vibration, noise increase of the motor, must also conform speed range of the motor bearing
and the mechanical device.
(5) For hoist and great inertia load, the inverter would shut off frequently due to
over-current or over-voltage failure in order to guarantee normal work. At this time, should
consider to choose the proper brake package.
(6) Should switch on/off the inverter through terminal or other normal order channels. It
is prohibited that switch on/off the inverter frequently by using strong electric switch such as
magnetic control conductor, otherwise will cause the equipment damage.
(7) If need to install such switch as the magnetic control conductor, etc. between
inverter output and the motor, please guarantee the inverter is switched on/off without output,
otherwise may damage the inverter.
(8) The inverter may meet with mechanical resonance of the load within certain range
of frequency output, can set up jumping frequency to evade.
(9) Before using, should conform the voltage of the power is within the working voltage
