VFD-L Series Instruction Sheet
1
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.
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:
¾
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.
¾ A charge may still remain in the DC-link capacitor with hazardous
voltages even 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.
¾ 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.
¾ There are highly sensitive MOS components on the printed circuit
boards. These 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.
¾ 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.

Wiring Notes: PLEASE READ PRIOR TO INSTALLATION.
¾ Do not connect the AC input to any of the U/T1, V/T2, W/T3
terminals, as it will damage the AC drive..
¾ Ensure all screws are tightened to the proper torque rating.
1. During installation, follow all national and local electrical, construction,
and safety codes for the country the drive is to be installed in.
2. Ensure the appropriate protective devices (circuit breaker or fuses) are
connected between the power supply and AC drive.
3. Make sure that the leads are connected correctly and the AC drive is
properly grounded. (Ground resistance should not exceed 0.1
Ω
.)
4. Use ground leads that comply with AWG/MCM standards and keep
them as short as possible.
5. 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
6. 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.
7. Make sure that the power is capable of supplying the correct voltage
and required current to the AC drive.
8. Do not attach or remove wiring when power is applied to the AC drive.
9. Do not monitor the signals on the circuit board while the AC drive is in
operation.
10. Route the power and control wires separately, or orthogonal to each
other.
11. 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.
12. 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).
13. When using a general GFCI (Ground Fault Circuit Interrupter), select a
current sensor with sensitivity of 200mA or above, and not less than
0.1-second operation time to avoid nuisance tripping. For the specific
GFCI of the AC motor drive, please select a current sensor with
sensitivity of 30mA or above.
