that, if not strictly observed, may result in per-
sonal injury or damage to the equipment.
WARNING:
FIRE AND PERSONAL INJURY HAZARD
This drive is designed for variable-speed opera-
tion of three-phase induction motors. It cannot
be used with single-phase motors or for any
other applications, otherwise fire may result.
The drive cannot be used by itself for elevators,
life-preservation equipment or other equipment
which is directly related to human safety. In such
situations, sufficient consideration should be
given to overall system configuration, not just to
the drive, otherwise serious accidents could
result.

dirt, metal shavings or other foreign objects get
inside the drive or onto the cooling fins, other-
wise fire or problems with operation may result.
AC input fuses are required to validate UL listing
of this device.
Do not install and operate the drive if it is dam-
aged or if some of the parts are missing. Doing
so may result in severe personal injury.
Do not touch the drive cooling fin because the
cooling fin reaches high temperatures during
operation, otherwise personal injury may result.
Install the drive in the environment of pollution
degree 2. If environment is pollution degree 3 or
4, the drive should be installed in a cabinet of
IP54. Required for CE Certification.
WIRING
WARNING:
FIRE AND ELECTRIC SHOCK HAZARD.
When connecting the drive to a power supply, be
sure to connect it via a circuit breaker, a leakage
current breaker or a fuse, otherwise fires may
result.
AC input fuses are required to validate the UL
listing of the drive.
Use only fuses and circuit breakers with rated
capacities that are suitable for use with the drive.
Failure to do so may result in fire.
Connect the drive with a secure ground, other-
wise electric shocks or fires may result.
Wiring work should only be carried out by suit-
ably qualified personnel, otherwise electric
shocks may result.
Make absolutely sure that the power supply is
turned off (open) before wiring, otherwise electric
shocks may result.
Wiring work should only be carried out after the
drive has been installed, otherwise electric
shocks or injury may result.

should only be carried out by suitably qualified
personnel. Remove any metallic accessories
such as watches and rings before starting work,
and use only properly insulated tools, otherwise
electric shocks may result.
DISPOSAL
CAUTION
Disposal of the drive should be entrusted to a
suitably-qualified disposal agency, otherwise
injury may result.
PACKING
CAUTION
Do not stand or sit on the drive as injury may
result.
The number of packing cartons that can be
stacked together is printed on the packing
container. Do not stack the containers any higher
than this or injury may result.
CAUTION:
Check that the phase and voltage of the AC
power supply being connected matches the
input phase and rated input voltage of the drive.
Using an improper power supply may cause
injury or damage to the equipment.
Do not connect AC power to the output termi-
nals (U, V, W) otherwise injury may result.
The drive, motor and wiring produce electromag-
netic noise during operation. Make sure that this
does not interfere with the operation of sensors
or other equipment nearby, otherwise accidents
may result.
OPERATION
WARNING:
ELECTRIC SHOCK HAZARD
Always install the drive cover before turning on
the power supply. In addition, do not remove the
drive cover while the power is on. Failure to
observe these precautions may result in electric
shocks.
Do not operate any of the switches with wet
hands, otherwise electric shocks may result.
WARNING:
FIRE AND PERSONAL INJURY HAZARD
If the retry function has been activated and a trip
occurs, the drive will restart automatically de-
pending on the cause of the trip. Make sure that
the system is set up properly so that there will be
no danger to personnel when the drive starts.
The STOP key is only effective when keypad
panel operation has been selected in the func-
tion settings. A separate switch should be
installed for emergency stopping purposes.
If an alarm reset is carried out while a run signal
(FWD/REV) is being input, the drive will suddenly
restart. Always check that the run signal is not
being input before carrying out the alarm reset,
otherwise accidents may occur.
Never touch the drive terminals while the power
is fed to the drive, regardless of whether the
drive is running or not.

CAUTION:
The control circuit terminal wiring should be
kept as far as possible from the main circuit
wiring to prevent operational error due to
noise interference. Never install them in the
same duct or conduit. (A separation distance
of 4 inches [10cm] or more is recom-
mended.) If the control circuit wiring must
cross the main circuit wiring, make sure it
crosses at a right angle.
Use shielded, twisted wire for the control
circuit wiring , which should be as short as
possible (65 feet [20m] or less).
Install a surge absorber in parallel with any
magnet contactors, solenoids, relays or

recommendation is Bussman type JKS or equivalent.
Long wiring lengths between the motor and
the drive will result in increased capacitance
and leakage current. This may cause earlier
activation of such protective functions as:
overcurrent protection, overheating protec-
tion and electronic thermal overload, or the
error in current detection may become large.
To avoid these, adjust the length of wiring
between the drive and the motor so that is
does not exceed the length shown below.

Outputs + 10VDC between FM and CM terminals. When
frquency setting is equal to the maximum frequency setting,
outputs + 10VDC at 150% current when monitoring output
current.
• Two DC voltmeters (internal resistance of 10K ohm or
greater) can be connected.
• In case of DC ammeter (1mA full scale), it is necessary to
add series resistance of 10K ohm (1/2W)
• This output is a pulse output constant frequency (38. 1 Hz)
which has a variable duty.

11. Operation
Pre-Operation Inspection
• Check for wiring errors.
• Check that all loose wire stands, metal
chips and unnecessary screws, etc. have
been removed.
• Check that no screws, terminals, etc. are
loose.
• Check that the wire ends of crimp terminal
are not in contact with other terminals.
Test Run Check Points
• Smooth rotation and correct rotation
direction.
• No abnormal vibrations and noise from
the motor.
• Smooth acceleration and deceleration.
Frequency Setting Method
• Frequency setting by potentiometer con-
trol (factory preset at the time of ship-
ment; F01:1). As wired at the factory,
frequency setting can be performed by
turning the potentiometer control knob on
the keypad panel. Turn the potentiometer
control knob clockwise to increase fre-
quency.
• Frequency setting by digital signal (F01 :
0). With the function F01 set to 0, fre-
quency can be increased or decreased by
the
UP/DOWN) keys on the keypad panel.
UP: Frequency up
DOWN: Frequency down
RUN/STOP Method
• RUN/STOP by keypad panel operation
(Factory preset at the time of shipment
F02:0).
• The drive is shipped with a factory in-
stalled jumper, between FWD-CM. Only
forward operation is possible. To enable
reverse operation, remove the jumper
from FWD/CM and install the jumper
between REV-CM.
• RUN/STOP by terminal operation (F02 : 1)
Note: Open FWD and REV terminals when
changing F02 data. Data cannot be changed
if not open.
