Product Confirmation And Operation Cautions 3
V560 Series High Performance Closed-Loop Vector Inverter User Manual
1.2.4 SAFETY CAUTION FOR MAINTENANCE CHECK
1. Maintenance operations of overhaul and device replacement only can be done by trained professional
maintenance staff. During operation, insulation protection tools shall be applied. It is strictly prohibited to
leave thrum and metal in the machine. Otherwise, there can be dangers of electric shock, fire, and
personal and property damage.
2. After replacement of control board, corresponding parameters must be set before operation; otherwise,
there can be danger of property damage.
1.3 KNOWLEDGE ON OPERATION
1.3.1 APPLICATION KNOWLEDGE OF DRIVING GENERAL MOTOR
1. The temperature when driving general motor applied with frequency converter can be a little higher than
that of industrial frequency power. With long-term operation at low speed, the operation life of motor can
be affected due to the poorer heat dissipation effect. In this case, special frequency converter shall be
selected or lighten the motor load.
2. If when the equipment is installed with frequency converter drive, sometimes, there can be resonance due
to the natural vibration frequency of mechanical system, please consider about applying flexible coupling
and insulation rubber, or applying the function of hopping frequency of the frequency converter, to avoid
the resonance point for operation.
3. There can be larger noise when driving general motor applied with frequency converter than that of
industrial frequency power. In order to reduce the noise, the carrier frequency of frequency converter can
be increased properly.
1.3.2 APPLICATION KNOWLEDGE OF DRIVING SPECIAL MOTOR
1. For high-speed motor, if the set frequency of frequency converter is above 120Hz, please conduct
combination test with motor, to make sure it can be operated safely.
2. For synchronous motor, there must be correspondences according to the types of motor. Please contract
the manufacturer for consultation.
3. Operation of single-phase motor is not applied with frequency converter. Even when input with single
phase, there is three-phase output, please apply with three-phase motor.
1.3.3 AMBIENT ENVIRONMENT
Application shall be applied in the indoor range with environment temperature of -10 to +45°C, humidity
around below 95% (without condensation of moisture), no dust, no direct sunlight, no corrosive gas, no
combustible gas, no oil mist, no steam, no water or floating fiber or mental particles; if there is special
requirements of clients, please contract the manufacturer for consultation.
1.3.4 CONNECTION KNOWLEDGE OF PERIPHERAL EQUIPMENT
1. For the protection of wirings, please configure breaker for wirings on the input side of frequency converter.
Please do not apply device with larger capacity than recommendation.
2. If it needs to switch to industrial frequency power and others, when installing electromagnetic contactor on
the output side of frequency converter, please switch after frequency converter and motor stop running.
3. When applying with motor thermal relay, if the wiring of motor is too long, sometimes it is affected with the
high-frequency current flowing through capacitance distributed with wiring, current below the set value of
thermal relay may also cause trip. In this case, please lower the carrier frequency, or apply with output
filter.
4. For noise interference, connection filter, magnet ring and shielded wire can be applied as corresponding
measures.
