1.2
Motor and mechanical load related
Compared with power frequency operation
FC100P is a voltage type inverter, the output voltage is PWM wave, which contains certain
harmonics. Therefore, the temperature rise, noise and vibration of the motor during use are slightly
increased compared with power frequency operation.
Constant torque low speed operation
When the frequency converter drives the ordinary motor to run at low speed for a long time, the
output torque will decrease due to the deterioration of the heat dissipation effect of the motor. If it is
in the long-term low-speed constant torque operation condition, it is recommended to choose a
frequency conversion motor.
Electronic thermal protection of the motor
When selecting a suitable motor, the inverter can effectively implement thermal protection for
the motor. If the power of the controlled motor does not match the inverter, you must adjust the motor
protection parameters or other protection measures to ensure the safe and reliable operation of the
motor.
above the rated frequency of the motor
If the motor is operated above its rated frequency, the noise will increase. It is necessary to pay
attention to the vibration of the motor, and at the same time to ensure that the motor bearings and
mechanical devices can meet the requirements of the operating speed range.
Lubrication of mechanical devices
For long-term low-speed operation, mechanical devices such as gearboxes and gears should be
regularly lubricated and maintained to ensure that the transmission effect can meet the needs of the
site.
mechanical resonance point
Avoid the mechanical resonance point of the load device or the motor by setting the jump
frequency of the inverter ( P8-09-P8-10 ) .
Motor Insulation Inspection
When the motor is used for the first time or after long-term storage, the motor insulation should
be inspected to avoid damage to the inverter due to deterioration of the motor insulation.
