Delta VFD-L series User Manual

VFD-L Series

Preface Thank you for choosing DELTA’s VFD-L series AC Drive. The VFD-L series is manufactured using high-quality components, material and incorporating the latest microprocessor technology available.

 Getting Started

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.

WARNING

Always read this manual thoroughly before using VFD-L series AC Motor Drives.

DANGER!

AC input power must be disconnected before any maintenance. Do not connect or disconnect wires and connectors while power is applied to the circuit. Maintenance must be performed by qualified technicians.

CAUTION! There are highly sensitive MOS components on the printed circuit boards.

These components are especially sensitive to static electricity. To avoid damage to these components, do not touch these components or the circuit boards with metal objects or your bare hands.

DANGER! A charge may still remain in the DC-link capacitor with hazardous voltages

even if 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 within the AC drive. Do not touch these live parts.

CAUTION! Ground the VFD-L using the ground terminal. The grounding method

must comply with the laws of the country where the AC drive is to be installed. Refer to Basic Wiring Diagram.

DANGER! The AC drive may be destroyed beyond repair if incorrect cables are

connected to the input/output terminals. Never connect the AC drive output terminals U/T1, V/T2, and W/T3 directly to the AC main circuit power supply.

Any electrical or mechanical modification to this equipment without prior written consent of Delta Electronics, Inc. will void all warranties and may result in a safety hazard in addition to voiding the UL listing.

General Wiring Information



Applicable Codes All VFD-L AC drives are Underwriters Laboratories, Inc. (UL) and Canadian Underwriters

Laboratories (cUL) listed, and therefore comply with the requirements of the National Electrical Code (NEC) and the Canadian Electrical Code (CEC).

Installation intended to meet the UL and cUL requirements must follow the instructions provided in “W iring Notes” as a minimum standard. Follow all local codes that exceed UL and cUL requirements. Refer to the technical data label affixed to the AC drive and the motor nameplate for el ectr i cal data.

The "Line Fuse Specification" in Appendix B, lists the recommended fuse part number for each B-Series part number. These fuses (or equivalent) must be used on all installations where compliance with U.L. standards is a required.

will damage the AC drive.



WARNING: Ensure all screws are tightened to the proper torque rating.

3. During installation, follow all local electrical, construction, and safety codes for the country the drive is to be installed in.

4. Ensure that 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 0.18.)

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.

8. When the AC drive output terminals U/T1, V/T2, and W /T3 are connected to the motor terminals U/T1, V/T2, and W/T3, 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 source 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.

ang le to each other.

14. 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.

15. 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), unless approved by Delta.

16. When using a GFCI (Ground Fault Circuit Interrupt), select current sensor with sensitivity of 200mA, and not less than 0.1-second detection to avoid nuisance tripping.

Pr.1-09. This parameter is used to determine the time required for the AC drive to ramp from 0 Hz to its Maximum Output Frequency (Pr.1-00). The rate is linear unless S-Curve is “Enabled.”

Pr.1-10. This parameter is used to determine the time required for the AC drive to decelerate from the Maximum Output Frequency (Pr.1-00) down to 0 Hz. The rate is linear unless S-Curve is “Enabled.”



The accel/decel time 2 determines the time for the AC drive to accel/decel from 0Hz to Maximum Output Frequency (Pr.1-00) (accel/decel time 1 is the default). A Multi-Function Input terminals must be programmed to select accel/decel time 2 and the terminals must be closed to select accel/decel time 2. See Pr.4-04 to Pr.4-08.



In the diagram shown below, the accel/decel time of the AC drive is the time between 0 Hz to Maximum Output Frequency (Pr.1-00). Suppose the Maximum Output Frequency is 60 Hz, start-up frequency (Pr.1-05) is 1.0 Hz, and accel/decel time is 10 seconds. The actual time for the AC drive to accelerate from start-up to 60 Hz is 9.83 seconds and the deceleration time is also 9.83 seconds.

The JOG function can be selected using Multi-function Input terminals (Pr.4-04 to

Pr.4-08) if programmed for Jog (d10). When the Jog terminal is “closed”, the AC drive will accelerate from Minimum Output Frequency (Pr.1-05) to Jog Frequency (Pr.1-14). When the Jog terminal “open”, the AC drive will decelerate from Jog Frequency to zero. The accel/decel time is decided by the Jog accel/decel time (Pr.1-13). During operation, the AC drive can not perform Jog command. And during Jog operation, other operation commands can not be accepted, except command of RUN/STOP key on the digital keypad.

These two parameters allow you to configure whether the acceleration and/or deceleration ramps are linear or S-shaped. The S-curve is enabled when set at d1-d7. Setting d1 offers the quickest S-curve and d7 offers the longest and smoothest S-curve. The AC drive will not follow the accel/decel time in Pr.1-09 to Pr.1-12. To Disable the S-curve, set Pr.1-16 and Pr.1-17 to d0.
