VLT® FCM Series

All operations must be carried out by ap­propriately trained personel.
Use all lifting facilities provided e.g. both
lifting points if fitted or single lifting point if
fitted*.
Vertical lifting - Prevent uncontrolled rota­tion.
Lift machine - Do not lift other equipment
with motor lifting points only.
Before installation check for fan cover
damage, shaft damage, foot/mounting
damage, and loose fasteners. Check
nameplate details.
Ensure level mounting surface, balanced
mounting, not misaligned.
Gaskets, and/or sealants, and guards
must be correctly fitted.
Correct belt tension.

Please observe derating rules, see "Special condi-
tions".

*Note: maximum hand lift is 20 kg below shoulder, but
above ground level. Max. gross weights:

Frame size 80: 15 kg

-

Frame size 90 & 100: 30 kg

-

Frame size 112: 45 kg

-

Frame size 132: 80 kg

-

The voltage on the FC motor is dangerous
when the motor is connected to mains. In­correct installation of the FC motor may
lead to material damage or serious injury,
or it may be fatal.
Consequently, the instructions in this
manual as well as national and local rules
and safety regulations must be complied
with.
Touching the electrical parts may be fatal,
even after the mains supply has been dis­connected. Wait at least 4 minutes.

- Installation must be fused and isolated
correctly.

- Covers and cable entries must be fitted.

NB!

It is the user's or certified electrician's re­sponsibility to ensure correct earthing and
protection in accordance with applicable
national and local requirements and
standards.

Safety regulations

1. The VLT DriveMotor (FC motor) must be dis­connected from mains if repair work is to be
carried out.
Check that the mains supply has been dis­connected and that the necessary time has
passed (4 minutes).

2. Correct protective earthing of the equipment
must be established, the user must be pro­tected against supply voltage, and the motor
must be protected against overload in ac­cordance with applicable national and local
regulations.
Use of RCD's (ELCB relays) is described in
chapter 10.

3. The earth leakage currents are higher than

3.5 mA. This means that the FC motor re­quires a fixed, permanent installation as well
as reinforced protective earthing.

Warning against unintended start

1. The motor can be brought to a stop by means
of digital commands, bus commands, or ref­erences, while the frequency converter is
connected to mains.
If personal safety considerations make it nec­essary to ensure that no unintended start
occurs,
cient .

2. While parameters are being changed, the
motor may start.

3. A motor that has been stopped may start if
faults occur in the electronics of the FC mo­tor, or if a temporary overload or a fault in the
mains supply ceases.

these stop functions are not suffi-

VLT® FCM Series

Integration of frequency converter and motor

The Danfoss VLT frequency converter integrated onto
the asynchronous motor gives infinite speed control in
one unit.

The VLT DriveMotor FCM 300 Series is a very com­pact alternative to the ordinary solution with VLT fre­quency converter and motor as separate units. The
frequency converter is attached instead of the motor
terminal box, and it is no higher than the standard ter­minal box, nor wider or longer than the motor (see
chapter 6).

Installation is made extremely easy. Panel space is not
a problem. There is no need for special details on wir­ing to meet the EMC directive, since motor cables are
not necessary. The only connections are mains and
control connections.

Factory-set adaption between frequency converter
and motor gives precise and energy efficient control in
addition to eliminating pre-setting on site.

The FC motor can be used in stand alone SYSTEMs
with traditional control signals, such as start/stop sig­nals, speed references and closed loop process con­trol or in multiple drive SYSTEMs with control signals
distributed by a field bus.

Combination of fieldbus and traditional control signals
and closed loop PID control is possible.

Handling the FC motor

Handling and lifting of VLT DriveMotors (FC motors)
must only be undertaken by qualified personnel. Full
product documentation and operating instructions
must be available together with tools and equipment
necessary for safe working practice. Eyebolts and/or
lifting trunnions supplied with the FC motor are de­signed to support only the weight of the FC motor, not
the weight of the FC motor and any auxcillary equip­ment attached to it. Be absolutely sure that cranes,
jacks, slings and lifting beams are capable of carrying
the weight of equipment to be lifted. Where an eyebolt
is provided with the motor, this should be screwed

Bearings

The standard solution is fixed bearing in the drive side
of the motor (shaft output side).
To avoid static indention, the storage area should be
vibration free. Where exposure to some vibration is
unavoidable, the shaft should be locked. Bearings may
be fitted with a shaft locking device which should be
kept in place during storage. Shafts should be rotated

down until its shoulder is firmly against the face of the
stator frame to be lifted.

Installation of the FC motor

VLT® FCM Series

FC motors must be installed with adequate access for
routine maintenance. A minimum of 0.75m of working
space around the motor is recommended. Adequate
space around the motor, particularly at the fan inlet (50
mm), is also necessary to facilitate airflow.
Where several FC motors are installed in close prox­imity, care must be taken to ensure that there is no
recirculation of exhausted warm air. Foundations must
be solid, rigid and level.

NB!

Electrical installation
Do not remove the top foil inside the in­verter part, as this is a part of the protec­tive arrangements.

Alignment

When the application calls for direct coupling, the
shafts must be correctly aligned in all three planes.
Bad alignment can be a major source of noise and vi­bration.

Fitting pinions, pulleys and couplings.

These should be bored to our standard limits and fitted
on the shaft with a screwing motion. Attention must be
paid to correct guarding of all moving parts.

Tapping of fitments onto the FC motor
shaft, with a hammer or mallet, causes
bearing damage. This results in an in­crease in bearing noise and a significant
reduction in bearing life.

NB!

Max. length of mounting bolts penetrating
the B14 flange, see section Dimensions in
this chapter.

Allowance must be made for shaft endfloat and ther­mal expansion in both axial and vertical planes. It is
preferable to use flexible drive couplings.

Maintenance

Routine cleaning of the FC motor
Remove the fan cover and ensure that all air inlet holes
are completely free. Clean any dirt and obstructions
from behind the fan and along the ribs of the frame,
and between the motor and inverter part.

Periodic maintenance of motor part.

a. Remove the inverter part, the fan cover and

Loosen and remove bearing cover screws
and endshield bolts/studs.The endshields

driven part, as misalignment will lead to ulti­mate bearing trouble and shaft breakage.

g. When replacing screws and bolts, care

should be taken to use only those with the
requisite quality and tensile strength recom­mended by the manufacturer. These must
also be of identical thread form and screw/
bolt length (see the table above).

Forced ventilation (FV) units

In some applications the fan built on to the motor shaft
do not give sufficient cooling for operation at low
speed. That problem is solved by mounting a FV unit.

Typical applications are for example conveyors, spin­dles and other constant torque (CT) applications
where the customer wants a wide control range with­out reduction in torque down to low speed.

The VLT Drive Motor yields full continuous torque
down to low speed with FV built on. The forced vent
enclosure is IP 66. Approved according to UL.

b. The rotor can now be carefully withdrawn

from the stator, taking care not to damage the
stator bore and both stator and rotor wind­ings.

c. Having dismantled the motor, maintenance

can be carried out to remove all dirt. For this
purpose, the use of an air line supplying dry
compressed air under comparatively low
pressure is best, as a high velocity air-stream
can force dirt into the spaces between the
windings and insulation, etc. Grease-remov­ing solvents can cause damage to impreg­nating varnish or insulation

d. The FC-motor should be re-assembled in the

reverse order from dismantling, remember­ing to ease endshields onto bearings and
spigots. DO NOT USE FORCE.

e. Before starting, check that the rotor revolves

freely. Ensure that the electrical connections
are correct.

f. Refit any pulley, coupling, sprocket etc.

Voltage range for forced ventilation (FV) unit

The FVU can be supplied with a wide range of voltages
depending on the way the terminals are connected.
Standard is three phase 380-500 V (50 Hz), 380-575

FCM 300 Thermal Protection

The thermal protection of FC and motor is covered in
the following way:

1. Overload situations are handled by the cal-

2

culated electrical load (I

X t).

2. Missing ventillation and high ambient tem­perature is handled by the temperature
measurement. The derating for low speed
(due to missing ventillation) is not incopora­ted in the electrical load calculaton but taken
care of by the temperature measurement.
Forced ventillation is thus automaticly cov­ered.

Electrical load
The current is measured in the DC link and the esti­mated load is calculated. The level of the electrical
load is set at an output torque of 105%. Above that
level a counter is increased, below the level it is de­creased. The counter starts at zero. When the counter
reaches 100, the unit trips. At 98 the warning indication
goes on (LED and status word).

V (60 Hz) with the possibility to connect three phase
220-290 V (50 Hz), 220-332 V (60 Hz) or single phase
230-277 V (50/60 Hz). The capacitor for single phase
is mounted inside the terminal box.

Trip level => Immediate trip and alarm indication (LED
and status word).

The value can be read in parameter 537 (LCP: Heat
sink temp.).

The temperature levels seem to be high, but due to a
local heating of the sensor the practical levels of the
inside air temperature are approx. 10 deg C lower.

minutes. If the function TEMP.DEP.SW is activated in
parameter 412, the switching frequency is decreased
gradually down to 2 kHz attempting to decrease the
temperature.
