Precautions
●
Motor Insulation Inspection
Motor in use for the first time, placed a long time before re-use and periodic inspection should
be done, the motor insulation should be checked, to prevent the motor AEding insulation
failure and damage to the inverter. To motor insulation check connection separate from the
inverter, 500V megohm is recommended, should ensure that the measured insulation
resistance of not less than 5MΩ.
● Motor Thermal Protection
If the rated capacity of the motor does not match those of the inverter, especially when the rated
power of the inverter is higher than the rated power of the motor, be sure to adjust the inverter
motor protection parameter values , or thermal relay shall be mounted for motor protection.
● Running with Frequency higher than Power Frequency
This inverter can provide output frequency from 0Hz to 500Hz. If the customer is required to
run 50Hz above, consider the mechanical endurance of the device.
● Vibration of Mechanical Device
The inverter may encounter the mechanical resonance point at certain output frequencies,
which can be avoided by setting the skip frequency parameters in the inverter.
●
Motor Heat and Noise
Since the output voltage of inverter is PWM wave and contains certain harmonics, the
temperature rise, noise and vibration of the motor comparing with the power frequency will be
increased slightly.
●
Use with the voltage different with the rated voltage
If the AE-V81series inverter is used outside the allowable working voltage range as specified
in this manual, it is easily lead to the inverter devices damage. If needed, use the
corresponding boost or lower voltage transformer processing.
●
The output side with the pressure-sensitive devices or to improve the power factor capacitor
Since the inverter output is PWM wave, the output side if installed with capacitors to improve
the power factor or piezoresistance. Easily lead to the inverter instantaneous over current or
even damage the drive, do not use.
●
Switching Devices like Contactors used at the Input and Output terminal
If a contactor is installed between the power supply and the input terminal of the inverter, it is
not allowed to use the contactor to control the startup/stop of the inverter. Necessarily need to
use the contactor control inverter start and stop of not less than an hour. Frequent charge and
discharge will reduce the service life of the capacitor inside the inverter. If switching devices
like contactor are installed between the output terminal and the motor, should ensure that the
inverter output off operation, otherwise easily lead to the inverter module damage.
● Change Three-phase Input to Two-phase Input
It is not allowed to change the AE-V81 series three-phase inverter into two-phase. Otherwise, it may
cause fault or damage to the inverter. This operation must be handed under AE-TECHNOLOGY
technical guidance.
