Preface
Thank you for choosing DELTA’s high-performance VFD-S Series. The VFD-S Series is
manufactured with high-quality components and materials and incorporates the latest microprocessor
technology available.
Getting Started
This quick start will be helpful in the installation and parameter setting of the AC motor drives. To
guarantee safe operation of the equipment, read the following safety guidelines before
connecting power to the AC motor drives. For detail information, refer to the VFD-S User Manual
on the CD supplied with the drive.
DANGER!
1. AC input power must be disconnected before any wiring to the AC motor drive is made.
2. A charge may still remain in the DC-link capacitors with hazardous voltages, even if the power
has been turned off. To prevent personal injury, please ensure that power has turned off before
opening the AC motor drive and wait ten minutes for the capacitors to discharge to safe voltage
levels.
3. Never reassemble internal components or wiring.
4. The AC motor drive may be destroyed beyond repair if incorrect cables are connected to the
input/output terminals. Never connect the AC motor drive output terminals U/T1, V/T2, and
W/T3 directly to the AC mains circuit power supply.
5. Ground the VFD-S using the ground terminal. The grounding method must comply with the laws
of the country where the AC motor drive is to be installed. Refer to the Basic Wiring Diagram.
6. VFD-S series is used only to control variable speed of 3-phase induction motors, NOT for 1-
phase motors or other purpose.
7. VFD-S series shall NOT be used for life support equipment or any life safety situation.
WAR NI NG!
1. DO NOT use Hi-pot test for internal components. The semi-conductor used in AC motor drive
easily damage by high-pressure.
2. There are highly sensitive MOS components on the printed circuit boards. These components
are especially sensitive to static electricity. To prevent damage to these components, do not
touch these components or the circuit boards with metal objects or your bare hands.
3. Only quality person is allowed to install, wire and maintain AC motor drive.
CAUTION!
1. Some parameters settings can cause the motor to run immediately after applying power.
2. DO NOT install the AC motor drive in a place subjected to high temperature, direct sunlight,
high humidity, excessive vibration, corrosive gases or liquids, or airborne dust or metallic
particles.
3. Only use AC motor drives within specification. Failure to comply may result in fire, explosion or
electric shock.
4. To prevent personal injury, please keep children and unqualified people away from the
equipment.
5. When the motor cable between AC motor drive and motor is too long, the layer insulation of the
motor may be damaged. Please use a frequency inverter duty motor or add an AC output
reactor to prevent damage to the motor. Refer to appendix B Reactor for details.
6. The rated voltage for AC motor drive must be ≤240V (≤480V for 460V models) and the mains
supply current capacity must be ≤5000A RMS (≤10000A RMS for the ≥40hp (30kW) models).

Over current
Abnormal increase in current.
Over voltage
The DC bus voltage has
exceeded its maximum
allowable value.
Overheating
Heat sink temperature too high
Low voltage
The AC motor drive detects
that the DC bus voltage has
fallen below its minimum
value.
Overload
The AC motor drive detects
excessive drive output current.
NOTE: The AC motor drive
can withstand up to 150% of
the rated current for a
maximum of 60 seconds.
Overload 1
Internal electronic overload trip
Overload 2
Motor overload.
Over-current during
acceleration
4. Check for loose contacts between AC motor
drive and motor.
5. Increase the Acceleration Time.
6. Check for possible excessive loading
conditions at the motor.
7. If there are still any abnormal conditions when
operating the AC motor drive after a shortcircuit is removed and the other points above
are checked, it should be sent back to
manufacturer.
1. Check if the input voltage falls within the rated
AC motor drive input voltage range.
2. Check for possible voltage transients.
3. DC-bus over-voltage may also be caused by
motor regeneration. Either increase the Decel.

4. Check whether the required braking power is
within the specified limits.
1. Ensure that the ambient temperature falls within
the specified temperature range.
2. Make sure that the ventilation holes are not
obstructed.
3. Remove any foreign objects from the heatsinks
and check for possible dirty heat sink fins.
4. Check the fan and clean it.
5. Provide enough spacing for adequate
ventilation.
1. Check whether the input voltage falls within the
AC motor drive rated input voltage range.
2. Check whether the motor has sudden load.
3. Check for correct wiring of input power to R-S-T
(for 3-phase models) without phase loss.
1. Check whether the motor is overloaded.
2. Reduce torque compensation setting in Pr.7-
02
3. Take the next higher power AC motor drive
model.
1. Check for possible motor overload.
2. Check electronic thermal overload setting.
3. Use a higher power motor.
4. Reduce the current level so that the drive
output current does not exceed the value set
by the Motor Rated Current Pr.7-00.
1. Reduce the motor load.
2. Adjust the over-torque detection setting to an
appropriate setting (Pr.6-03 to Pr.6-05).
1. Short-circuit at motor output: Check for
possible poor insulation at the output lines.
2. Torque boost too high: Decrease the torque
