7.3 Cautions in operation with inverter
①
Higher temperature rise, noise and vibration than that from the general power
source will be observed. Especially, low speed rotation which naturally reduce the fun
effect, may cause abnormal rise of temperature.
(More than 80˚C at the surface of the motor.)
②
In the gearmotor with brake or with clutch/brake, malfunction of the brake may be
observed due to the voltage drop. In order to avoid this disadvantage, be sure to by
pass the inverter when wiring the brake clutch.
②
It is feasible to use inverter in the single-phase motor.
③
When using inverter in the 400V class motor, consult with Inverter manufacturer
concerning the micro surge voltage.
