Highly VFD Variable Frequency Drive with Acceleration and Deceleration Time Switching
Motor Speed Control VFD Variable Frequency Drive With GPRS And SVC Algorithm
1. VFD500 series product features for reference
1) Independent air dust design, effectively preventing dust entering inverter, causing short-circuit and other faults and improving reliability. Besides, the kind of design can help to extend the life of the product.
2) VEIKONG continues to make applications even smaller by combining the compact designed drive with the light, efficient design of a synchronous motor.
3) High speed accuracy and wide speed range Steady speed accuracy: ±0.5% (SVC), ±0.02% (VC) Speed range: 1:200 (SVC), 1:1000 (VC) Heavy load overload capability: 110% rated current for long-term stable operation 150% rated current for 1 minute 180% rated current 10s

5. Motor Wiring
◆ It is forbidden to short circuit or ground the inverter output terminal, otherwise the internal components of the inverter will be damaged.
◆ Avoid short circuit the output cables or with the inverter enclosure, otherwise there exists the danger of electric shock.
◆ It is forbidden to connect the output terminal of the inverter to the capacitor or LC/RC noise filter with phase lead, otherwise, the internal components of the inverter may be damaged.
◆ When contactor is installed between the inverter and the motor, it is forbidden to switch on/off the contactor during the running of the inverter, otherwise, there will be large current flowing into the inverter, triggering the inverter protection action.
◆ Length of cable between the inverter and motor If the cable between the inverter and the motor is too long, the higher harmonic leakage current of the output end will produce by adverse impact on the inverter and the peripheral devices. It is suggested that when the motor cable is longer than 100m, output AC reactor be installed. Refer to the following table for the carrier frequency setting
