1.4 Notes on the application 1.4.1 Motors Mandatory When the VF-FS1 and the motor are used in conjunction, pay attention to the following items. Caution A-13 E6581381 Use an inverter that conforms to the specifications of power supply and three-phase induction motor being used. If the inverter being used does not conform to those specifications, not only will the threephase induction motor not rotate correctly, but it may cause serious accidents through overheating and fire. Comparisons with commercial power operation. The VF-FS1 Inverter employs the sinusoidal PWM system. However, the output voltage and output current are not perfect sine waves, they have a distorted wave that is close to sinusoidal waveform. This is why compared to operation with a commercial power there will be a slight increase in motor temperature, noise and vibration. Operation in the low-speed area When running continuously at low speed in conjunction with a general purpose motor, there may be a decline in that motor's cooling effect. If this happens, operate with the output decreased from rated load. To carry out low-speed operation continuously at the rated torque, we recommend to use a inverter rated motor or a forced cooled motor designed for use with an inverter. When operating in conjunction with a inverter rated motor, you must change the inverter's motor overload protection level to VF motor use (). Adjusting the overload protection level The VF-FS1 Inverter protects against overloads with its overload detection circuits (electronic thermal). The electronic thermal's reference current is set to the inverter's rated current, so it must be adjusted in line with the rated current of the general purpose motor being used in combination. High speed operation at and above 60Hz Operating at frequencies greater than 60Hz will increase noise and vibration. There is also a possibility this will exceed the motor's mechanical strength limits and the bearing limits so you should inquire to the motor's manufacturer about such operation. Method of lubricating load mechanisms Operating an oil-lubricated reduction gear and gear motor in the low-speed areas will worsen the lubricating effect. Check with the manufacturer of the reduction gear to find out about operable gearing area. 1
1 Low loads and low inertia loads A-14 E6581381 The motor may demonstrate instability such as abnormal vibrations or overcurrent trips at light loads of 5 % or under of the load percentage, or when the load's inertia moment is extremely small. If that happens reduce the carrier frequency. Occurrence of instability Unstable phenomena may occur with the load and motor combinations shown below. ⋅ Combined with a motor that exceeds applicable motor ratings recommended for the inverter ⋅ Combined with special motors To deal with the above lower the settings of inverter carrier frequency. ⋅ Combined with couplings between load devices and motors with high backlash When using the inverter in the above combination, use the S-pattern acceleration/deceleration function, or when vector control is selected, adjust the speed control response/stability factor or switch to V/F control mode. ⋅ Combined with loads that have sharp fluctuations in rotation such as piston movements In this case, please do not use this inverter. Braking a motor when cutting off power supply A motor with its power cut off goes into free-run, and does not stop immediately. To stop the motor quickly as soon as the power is cut off install an auxiliary brake. There are different kinds of brake devices, both electrical and mechanical. Select the brake that is best for the system. Load that produces regenerative torque Do not use the inverter in combination with a load, such as an air conditioner, that produces regenerative torque. Or the overvoltage or overcurrent protection circuit of the inverter may be activated, causing the inverter to trip. If overvoltage tripping occurs during deceleration, lengthen the deceleration time.
