Preface
Thank you for choosing DELTA’s high-performance VFD-F Series. The VFD-F 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-F 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-F 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-F series is used only to control variable speed of 3-phase induction motors, NOT for 1-
phase motors or other purpose.
7. VFD-F series shall NOT be used for life support equipment or any life safety situation.
WARNING!
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 subje c ted 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 mo tor 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).

4. Check the fan and clean it.
5. Provide enough spacing for adequate ventilation.
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.
1. Check whether the input voltage falls wit hin the AC mo tor
drive rated input voltage rang e.
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.
NOTE: The AC motor drive can withstand up to 150% of the
rated current for a maximum of 60 seconds.
1. Check for possible motor overload.
Overload 1

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.
Overload 2
Motor overload.
1. Reduce the motor load.
2. Adjust the over-torque detection setting to an appropriate

2. Check if the communication protocol is pr op erl y set.
1. Short -circuit at motor output: Check for possible poor
insulation at the output lines.
2. Torque boost too high: Decrease the torque compensation
setting in Pr.7-02.
3. Acceleration Time too short: Increase the Acceleration Time.
4. AC motor drive output power is too small: Replace the AC
motor drive with the next higher power model.
1. Short -circuit at motor output: Check for possible poor

2. Press RESET after fault has been clea red.
1. Turn off the power.
2. Check whether the input voltage falls within the rated AC

1. Check if the motor is suitable for operation by AC motor
drive.
2. Check if the regenerative energy is too large.
3. Load may have changed suddenly.
When (one of) the output termina l(s ) is gr ound ed, sh ort c irc uit
current is more than 50% of AC motor drive rated current, the AC
motor drive power module may be damaged.
NOTE: The shor t ci r cuit protection is pr ovi d e d for AC m ot or
drive protection, not for protection of the user.
1. Check whether the IGBT power module is damaged.
2. Check for possible poor insulation at the output line.
1. Check parameter settings and wiring of Analog feedback
(Pr.10-00).
2. Check for possible fault between system response time and
the feedback signal detection t i me (P r. 10-0 8).
