1-1

WARNINGS

MECHANICAL MOTION
HAZARD: Drive systems cause mechanical

motion. It is the responsibility of the user to
insure that any such motion does not result in
an unsafe condition. Customer provided
interlocks, and operating limits should not be
bypassed or modified.

ELECTRICAL SHOCK
AND BURN HAZARD: When using

instruments such as oscilloscopes to work on
live equipment, the oscilloscope’s chassis
should be grounded and a differential amplifier
input should be used. Care should be used in
the selection of probes and leads and in the
adjustment of the oscilloscope so that accurate
readings may be made. See instrument
manufacturer’s instruction book for proper
operation and adjustments to the instrument.

FIRE AND EXPLOSION
HAZARD: Fires or explosions might result

from mounting Drives in hazardous areas such
as locations where flammable or combustible
vapors or dusts are present. Drives should be
installed away from hazardous areas, even if
used with motors suitable for use in these
locations.

STRAIN HAZARD:

Improper lifting practices can cause serious or
fatal injury. Lift only with adequate equipment
and trained personnel.

ELECTRICAL SHOCK
HAZARD: All motor bases and equipment

enclosure housings should be grounded in
accordance with the National Electric Code or
equivalent.

(AVERTISSEMENT)
HAZARD OF ELECTRICAL SHOCK

(RIS QUE DE CHOC ELECTRIQUE)

- Separate motor overcurrent, overload, and
overheating protection is required to be
provided in accordance with the Canadian
Electrical Code, Part 1.

- (Le moteur dolt etre muni d'une protection
distincte contre les surintensites, la
surcharge et la surchauffe confrmement au
Code Canadian de L'electricite, premierb
partie.)

The Drive leakage current to
ground is higher than 3mA. Use grounding
conductor as specified in Table 250-95 of
National Electric Code, ANSI/NFPA 70-1993 or
Table 31 CSA22.2, No. 14-M91.

HAZARD OF MOTOR
OVERSPEED:

ANY APPLICATIONS REQUIRING OPERATION
ABOVE 120 HZ MUST BE APPROVED BY THE

MOTOR MANUFACTURER.
Bias frequency setting is available when analog

frequency setting method (i.e. the Function
code "01" data is set at 1) is selected. At the
stop condition, the reference frequency will be
blinking on the LED display. If the Bias
frequency is set at a certain level and the
reference frequency is Zero, during the stop
condition, the display will be blinking Zero.
Thus, when a RUN command is given to the
Drive, the motor will run at the Bias frequency
setting (up to 400 Hz) even if the reference
frequency is Zero.
With 400 Hz Drive output possible, the Drive will
allow the motor to run up to 6 - 7 times its base
speed. Never operate the motor above its top
mechanical speed or a catastrophic failure may
occur.

Before disassembling,

disconnect and lock out power from the Drive.
Failure to disconnect power may result in death
or serious injury. A bus charge Light "CRG"
provides visual indication that bus voltage is
present; verify the bus voltage level by
measuring the voltage between power terminals
P(+) and N(-) using an analog meter. Do not
attempt to service the Drive until the charge
indicator ("CRG" lamp) has extinguished and
the bus voltage has discharged to zero volts.

Replace all covers before

applying power to the Drive. Failure to do so
may result in death or serious injury.

CAUTIONS

This product is suitable for use

on a circuit capable of delivering not more than
1,000 (1HP or less) or 5,000 (2 HP or more) rms
symmetrical amperes.
AC input fuses to be customer supplied and may
be branch circuit protection fused. The maximum
allowance fuse ratings per TABLE 4.

Do not connect power supply
voltage that exceeds the standard specified
voltage permissible. If excessive voltage is
applied to the Drive, damage to the internal
components will result.

Do not connect power supply to

the output terminals (U, V, W). Connect power
supply only to the power terminals (L1, L2, L3).

Do not connect power supply to

the breaking resistor connection terminals (P (+),
DB). Never short-circuit between P (+) – DB
terminals, and do not connect any resistance with
an ohm and/or wattage value less than standard
application breaking resistor.

Do not connect a power supply

to the control circuit terminals (except 30A, B, C,
maximum rating 250 volts, 0.3A ac/dc).

For RUN and STOP, use the

FWD-CM (forward) and REV-CM (reverse)
terminals. Do not use a contactor (ON/OFF)
installed on the line side of the Drive for RUN and
STOP.

Do not use a switch on the

output side of the Drive for ON/OFF operation.

Do not connect power factor

correcting capacitors on the output side of the
Drive.

Do not operate the Drive

without the ground wire connected. The motor
chassis should be grounded to earth through a
ground lead separate from all other equipment
ground leads to prevent noise coupling. The
grounding connector shall be sized in accordance

with the NEC or Canadian Electrical Code. The
connection shall be made by a UL listed or CSA
certified closed-loop terminal connector sized for
the wire gauge involved. The connector is to be
fixed using the crimp tool specified by the
connector manufacturer.

Do not perform a megger test

between the Drive terminals or on the control
circuit terminals.

The Drives are an IGBT drive

which develops an adjustable frequency via pulse
width modulation. While this does not present a
problem on 200-240 VAC applications, it may on
380-480 VAC applications. When using the
Drives on 380-480 VAC, get the motor
manufacturer's approval that his insulation system
can withstand the voltage spikes (up to twice the
dc bus voltage 2 x 621 VDC for a 480 VAC power
source of the Drive, in conjunction with the long
motor cable lengths). If the insulation system
does not meet this limit, utilize a RLC filter.

Because the ambient

temperature greatly affects Drive life and
reliability, do not install the Drive in any location
that exceeds the allowable temperature. Leave
the ventilation covers attached for temperatures
of 40 degrees C or below, and remove the
ventilation port side and top covers for
temperatures of between 40 (104° F) and 50
(122° F) degrees C. If the covers need to be

removed, another type of enclosure may be
required for safety purposes.

If the Drive’s Fault Alarm is

activated, consult the TROUBLESHOOTING
section of this instruction book, and after
correcting the problem, resume operation. Do
not reset the alarm automatically by external
sequence, etc.

Be sure to remove the desic-

cant packet(s) when unpacking the Drive. (If not
removed these packets may become lodged in
the fan or air passages and cause the Drive to
overheat.)

1-3

CAUTIONS (continued)

AC induction motors require
that they be sized based on the applications speed
range and associated torque requirements for the
motor-Drive system; this is to avoid excessive
motor heating. Observe motor manufacturer's
recommendations when operating any ac induction
motor with the Drive. Also observe motor
manufacturer's recommended voltage/torque boost
at lower operating frequencies.

The available power source con-

nected to the Drive is not to exceed 500KVA. If the
ac power source is greater than 500KVA and the
Drive's rated (HP) is less than 10% of the power
source's KVA; ac line reactors will have to be installed
in L1, L2 & L3 power leads of the Drive.

NOTES

NOTE:

① When terminal operation mode (Function code

F_02 setting is 1) - RUN and STOP are being
controlled by a maintained contact (e.g., selector
switch, toggle switch, etc.) which is connected
between the terminal CM and FWD or REV:

• Closing/opening the maintained contact starts/
stops the Drive.

The Drive must be mounted on

a building or enclosure wall that is constructed of
heat resistant material. While the Drive is operat­ing, the temperature of the Drive's cooling fins can
rise to a temperature of 90°C (194°F.)

If the Drive protective function

is activated, consult Section 8 "Troubleshooting",
and after correcting the problem, resume opera­tion. Do not reset the alarm automatically by
external sequence, etc.

Be sure to provide fuses, as

specified on "Application of Wiring And Equipment"
in Section 4, on line terminals of Drive. Provide
power line disconnect or contactor as needed.

INSTALLATION GUIDELINES

INSTALLATION ENVIRONMENT

Install the Drive in an indoor location that meets the
following requirements:

— The ambient temperature is between -10° C and

+50° C (+14° F to +122° F). Remove the ventila­tion covers when the temperature exceeds +40° C
[+104° F].

— The relative humidity is between 20% and 95%.

Avoid any location subject to condensation, freezing,
or where the Drive would come in contact with water.

— Do not install in any location subject to direct sunlight,

dust, corrosive gas, inflammable gas, or oil mist.

— Vibration should be less than 0.6G.
— The Drive should be installed at an elevation below

1000 meters (3281 feet). For installation above 1000
meters (3300 feet) the Drive will need to be derated
1% per 333 feet.

Example: 5 HP, 460 VAC, output current 9 amps.

Application altitude 3900 feet.

3900 - 3300

% derate = x 1% = 1.8%
(9 amps) x = 8.84 amps

INSTALLATION MOUNTING

CLEARANCE

— Install at a sufficient distance from other equip-

ment, walls, or wiring ducts as shown in Figure
3-1 (these clearances are required to allow the
heat generated by the Drive to escape).

— Install the Drive perpendicular to the ground and

with the lettering right side up. (If the Drive is
installed upside-down or horizontally, heat build­up will occur.)

— Mounting screws or bolts should be of appropriate

size for weight of Drive.

— See the appropriate figures on pages 3-2 and

3-3 for the location of mounting holes.

— After removing the knockouts in the wiring lead-in

plate, install the rubber bushings supplied to pre­vent cable damage and to minimize dust entry.

CAUTION: The mounting wall for the Drive must be

constructed of heat resistant material because during
operation, the temperature of the Drive's cooling fins
rises to approximately 90 degrees C (194° F).

Motor derate may also be required,
contact motor manufacturer.

CAUTION: Because the ambient temperature greatly

affects Drive life and reliability, do not install the Drive in
any location that exceeds the allowable temperatures.

Control Circuit Wiring

Drive is wired at shipment for operation and frequency
setting through the keypad panel (frequency is set at 60
Hz.)

– See Figure 4-2, and 4-4 for wiring connections.
– See TABLE 5 for description of all terminals.

Make wire connections as shown in Figure 4-4 through 4-6
for desired mode of external operation through Control
Circuit Terminals.

CAUTION: The Control Circuit Terminal wiring should be

kept as far away as possible from the main power wiring to
prevent operational error due to noise interference. Never
install both types of wiring in the same duct or conduit. (A
separation distance of 4 inches [10 centimeters] or more is
recommended.) If the control circuit wiring must cross the
main power wiring, it should cross at a right angle.

CAUTION: Use shielded or twisted wire for the control

circuit wiring (wiring should be as short as possible, i.e. 65
feet or less [20 meters.]) Connect outer covering of the
shielded wires to the Drive ground terminal and leave the
other end open, but taped with electrical insulating tape.

PRE-OPERATION INSPECTION

After mounting and wiring has been completed, check the Drive for the following items before applying AC power:

— Check for wiring errors.
— Verify that there are no wiring chips, screws, etc. remaining in the Drive.
— Check that all screw and terminal connections are tight.
— Verify that no exposed wire ends are touching other terminals.

KEYPAD PANEL IDENTIFICATION / OPERATION

See the following diagrams for Display and Keypad Operation description when in the Operation Mode, Program
Mode or Trip Mode.

FUNCTION CODE AND DATA CODE DESCRIPTION / SELECTION

When AC power is applied to the Drive, the keypad panel display will be as shown in Figure 5-1 and will be
flashing on and off. If the RUN key is pressed at this point, operation will be at 60 Hertz according to the

Function Code set at the factory. (Use the STOP key to halt operation.)

-- A Flashing display indicates when a run command is not present.

-- A Solid display indicates the actual output when the Drive is running.

If a test run is desired, press the key to change the flashing display of 60.00 Hz frequency setting to

5.00 Hz. Press RUN to conduct the test run and check for smooth motor operation and direction of rotation.
Removal of AC power will store a frequency reference in memory.

Pre-Operation Inspection

After completion of installation and wiring work, inspect the following items before the power supply to the Drive is
switched on.

CAUTION:

1. Check for wiring errors. (Especially the main circuit wiring: connection of the three
(single) phase AC power supply to the terminals L1, L2, L3 (L1, L2)).

2. Check that all loose wire strands, metal chips and unnecessary screws, etc. have been removed.

3. Check that all screws, terminals, and components are tight.

4. Check that the wire ends of crimp terminals are not in contact with other terminals.

CAUTION: Megger Test:
Do not conduct megger tests between the Drive main circuit terminals, or control circuit terminals.
Refer to Section 7 "Maintenance and Inspection."

Test Run Check Points

Use a low frequency reference setting of about 5 Hz to test Drive operation.
The following operating conditions must be confirmed:

1. Smooth motor rotation.

2. Correct direction of equipment rotation.

3. No abnormal vibrations and noise from the motor over full speed range.

4. Smooth acceleration and deceleration over full speed range.

Selecting Operation Method

The following methods can be selected to input the RUN/STOP signals and for frequency setting.

MAINTENANCE and INSPECTION

To prevent potential problems and provide long periods of trouble-free operation, the following checks should be
periodically conducted.

CAUTION: Do not conduct any inspections until after disconnecting

the power supply and after the “CRG” light on the Drive has gone out.

MEGGER TEST

1. Disconnect all Drive terminals and never apply test voltage to the Drive when conducting an external circuit
megger test. Use a 250 VDC megger for 230/240V input Drives and a 500VDC Megger for 480V input Drives.

2. Perform the test only on the main circuit as shown in Figure 7-1 when conducting a megger test on the Drive itself.
— Do not conduct a megger test on the control circuits.

— Short L1, L2, L3, U, V, W, P1, P(+), and DB, then megger to the Drive ground terminal E(G).

3. Use a high resistance range type tester to conduct a continuity test on the control circuits and not a megger or
a buzzer.

PERIODIC PARTS REPLACEMENT

The life of the Drive will vary according to the installation environment and the amount of running time. However, if
continuous operation is within the allowable limits, the life of the DC Link capacitor is approximately five years and
the life of the cooling fan is approximately three years. It is recommended that these parts be replaced before failure
occurs.

MEASUREMENT POINTS AND METERS

Since the Drive's input/output voltage and current contain high frequencies, selection of the wrong measuring device
can lead to gross miscalculations. When using a CT (current-detection transformer) to measure the current, the amount
of error will be large if the frequency is low. Because of this, always use a CT with as large a capacity as possible. See
the following chart and Figure 7-2 for recommended measurement devices.

Function Explanation Protective OperationDisplay

Protects the Drive if
the Drive output
current momentarily
exceeds the
overcurrent detection
level. Protects the
Drive from
overcurrent resulting
from an output phase
to-phase or phase-to­ground short circuit.

Avoids loss of control of the Drive
caused by drops in the power supply.
NOTE: Operation will continue if the
momentary power failure or under­voltage period is less than 15 msec.

Protects the Drive if
momentary
overvoltage
(regenerative
overvoltage) exceeds
the overvoltage
detection level.

Detects overheating of the Drive
caused by an overload, cooling
fan problem or abnormal ambient
temperature.

Acts as an external alarm to stop
output. If protective device such
as the overload relay is connected
between THR and CM terminals
switches from ON to OFF.

Protects semiconductor devices
such as the IGBT from overloads.

Protects a standard 4-pole motor
or a forced air cooled motor from
overloads even if an overload
relay is not connected.

Electromagnetic Compatibility (EMC)

General

In accordance with the provisions described in the
European Commission Guidelines Document on
Council Directive 89/336/EEC, GE Fuji Electric Co.,
Ltd. has chosen to classify the 1 phase, 240 VAC,
3 phase 415 VAC range of Drives as “Complex
Components”. Classification as “Complex
Components” allows a product to be treated as an
“apparatus”, and thus permits compliance with the
essential requirements of the EMC Directive to be
demonstrated to both an integrator of Micro-$aver II
Drive and to his consumer or the installer and user.

Micro-$aver II Drives up to 5 Hp are supplied ‘EC ­marked’, signifying compliance with EC Directive 89/
336/EEC when fitted with specified filter units
installed and earthed in accordance with this sheet..
This specification requires the following
performance criteria to be met.

Emissions will be predominantly conducted through
the motor and the main supply cables, although
some radiated emissions will be detected in close
proximity to the drive system. It is essential that
precautions are taken at the design stage, and at
the time of installation, to prevent radio frequency
interference. (RFI) from the dr ive system affecting
sensitive equipment in close proximity.

The RFI filters range are designed especially for the
Micro-$aver II Drive and help to ensure EMC
compliance of machinery as installations using
Inverters. The Drives may be mounted on top of the
filter using integral fixing positions, the intention
being that valuable space inside wiring cabinets
may be saved. (Refer to Fig. 10 - 1 and Table 10- 1)

Immunity : EN50082 - 2
Emissions : EN50081 - 1

RFI Filters

It is strongly recommended that the appropriate
Micro-$aver II Drive input filter be used to limit RF
current flowing into the main supply circuit. (Refer to
Table 10-1.) Without an input filter a Micro-$aver II
Drive installation may not meet statutory
requirement. Micro-$aver II Drive contain high ­power semi - conductor devices which are switched
at high speeds to synthesize a near - sinusoidal
current waveform across the frequency range of
output. Rapidly changing voltages and currents will
generate some degree of electromagnetic emission.

Recommended Installation Instructions

These instructions must be followed in order to
conform to the EMC Directive. Follow the usual
safety procedures when working with electrical
equipment. All electrical connections to the filter,
Inverter, and motor must be made by a qualified
electrical technician. (Refer to Fig.2, Fig. 3, and
Fig.4)

1. Check the filter rating label to ensure that the
current, voltage rating, and part number are
correct.

2. The back panel of the wiring cabinet board should
be prepared for the mounting dimensions of the
filter. Care should be taken to remove any paint
etc. from the mounting holes and face area
around the hole of the panel. This will ensure the
best possible earthing of the filter.

3. The filter should be securely mounted in position,
and the Inverter mounted to the front of the filter
with the screws provided.

4. Connect the incoming main supply to the filter
terminals marked “LINE” and any earth cables to
the earth stud provided. Fit the Input Ferrite Ring

(if two ferrite rings are required, refer to table 1),
and connect the filter terminals marked “LOAD” to
the main input of the of the Drive using a short
length of appropriate gauge wire.

5. Fit the output Ferrite Ring as close to the Inverter
as possible and connect the motor. Armored or
screened cable should be used with the 3 phase
conductors passing twice through the center of
the Output Ferrite Ring. The earth conductor
should be securely earthed at both the ground
terminal in the cabinet and at the motor ends. The
screen should be connected to the enclosure.

6. It is important that all lead lengths are kept as
short as possible and that incoming mains and
outgoing motor cables are kept well separated.

7. Segregate power cables from control wiring, as
thoroughly as possible, and avoid parallel cable
run to minimize ‘noise coupling’. When ever runs
of power and control cable must cross, try to
achieve this at right angles.

8. Micro-$aver II Drive should be installed, and are
designed to operate, with an electrically ­shielded metal enclosure.
