The VFD-L series is manufactured using high-quality components, material and incorporating the latest microprocessor technology available. This manual will help in the installation, parameter setting, troubleshooting, and daily maintenance of the AC motor drive. To guarantee safe operation of the equipment, read the following safety guidelines before connecting power to the AC motor drive. Keep this operating manual handy and distribute to all users for reference. Important Notes: T DANGER! AC input power must be disconnected before any maintenance. Do not connect or disconnect wires while power is applied to the circuit. Only qualified technicians should perform maintenance on the VFD-L. T CAUTION! There are highly sensitive MOS components on the printed circuit boards. These T DANGER! A charge may still remain in the DC-link capacitor with hazardous voltages even T T components are especially sensitive to static electricity. To avoid damaging these components, do not touch the circuit boards with metal objects or your bare hands. after the power has been turned off. To avoid personal injury, do not remove the cover of the AC drive until all “DISPLAY LED” lights on the digital keypad are off. Please note that there are live components exposed when the AC drive is open,. Be careful to not touch these live parts. The grounding method must CAUTION! Ground the VFD-L using the ground terminal. comply with the laws of the country where the AC drive is to be installed. DANGER! The AC drive may be destroyed beyond repair if power is misapplied to the input/output terminals. Never connect the AC drive output terminals U/T1, V/T2, W/T3 directly to the AC main circuit power supply. 1 Chapter 1 Receiving and Inspection This VFD-L AC drive has gone through rigorous quality control tests at the factory before shipment.

CAUTION: Do not connect the AC input to any of the U/T1, V/T2, W/T3 terminals, as it will damage the AC drive. WARNING: Ensure all screws are tightened to the proper torque rating. 3. During installation, follow all national and local electrical, construction, and safety codes for the country the drive is to be installed in. 4. Ensure the appropriate protective devices (circuit breaker or fuses) are connected between the power supply and AC drive. 5. Make sure that the leads are connected correctly and the AC drive is properly grounded. (Ground resistance should not exceed 0.1Ö .) 6. Use ground leads that comply with AWG/MCM standards and keep them as short as possible. 7. Multiple VFD-L units can be installed in one location. All the units should be grounded directly to a common ground terminal. The VFD-L ground terminals may also be connected in parallel, as shown in the figure below. Ensure there are no ground loops. Forward running 9/ When the AC drive output terminals U/T1, V/T2, and W/T3 are connected to the motor terminals U, V, and W, respectively, the motor will rotate counterclockwise (as viewed from the shaft ends of the motor) when a forward operation command is received. To reverse the direction of motor rotation, switch over any of the two motor leads. 9. Make sure that the power is capable of supplying the correct voltage and required current to the AC drive. 10. Do not attach or remove wiring when power is applied to the AC drive. 11. Do not monitor the signals on the circuit board while the AC drive is in operation. 12. Route the power and control wires separately, or orthogonal to each other. 13. If a filter is required for reducing EMI (Electro-Magnetic Interference), install it as close as possible to AC drive. EMI can also be reduced by lowering the Carrier Frequency. 14. If the AC drive is installed in the place where a load reactor is needed, install the filter close to U/T1, V/T2, W/T3 side of AC drive. Do not use a Capacitor or L-C Filter (Inductance-Capacitance) or R-C Filter (Resistance-Capacitance). 15. When using a GFCI (Ground Fault Circuit Interrupt), select current sensor with minimum current 200mA, and minimum detection time 0.1-second to avoid nuisance tripping. 6 Chapter 3 Summary of Parameters Group 0: User Parameters Parameters 0-00 0-01 = = = 0-02 0-03 0-04 0-05 0-06 0-07 0-08 =The parameter may be set during operation.
