Delta VFD-L Series User manual

VFD-L Series
DELTA ELECTRONICS, INC. ALL RIGHTS RESERVED
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.

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 “Wiring 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 electrical 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.

3.5 Wiring Notes: PLEASE READ PRIOR TO INSTALLATION.
1.

CAUTION: Do not connect the AC power to the U/T1, V/T2, W/T3 terminals, as it
will damage the AC drive.
2.

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 0.1
8
.)
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
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.

VFD-L Series
DELTA ELECTRONICS, INC. ALL RIGHTS RESERVED
3-6
11. Do not monitor the signals on the circuit board while the AC drive is in operation.
12. For the single-phase rated AC drives, the AC power can be connected to any two of the
three input terminals R/L1, S/L2, T/L3. Note: This drive is not intended for the use
with single-phase motors.
13. Route the power and control wires separately, or at 90
+
angle 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.
