FCM 300 Series
Design Guide
Software version: 3.1x
This Design Guide can be used for all FCM 300 Series frequency
converters with software version 3.1x.
The software version number can be seen from parameter 624
Software version no.
Table 1.1
1.1.2 Disposal Instruction
Equipment containing electrical
components may not be disposed of
together with domestic waste.
It must be separately collected with
electrical and electronic waste according
to local and currently valid legislation.
Table 1.2
1.1.3 Symbols
The following symbols are used in this Design Guide and
require special attention.
WARNING
Indicates a potentially hazardous situation which, if not
avoided, could result in death or serious injury.
NOTICE
Indicates highlighted information that should be
regarded with attention to avoid mistakes or operate
equipment at less than optimal performance.
CAUTION
Indicates a potentially hazardous situation which, if not
avoided, may result in minor or moderate injury. It may
also be used to alert against unsafe practices.
1.1.4 General warnings
NOTICE
All operations must be carried out by appropriately
trained personnel.
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 4.1 Special Conditions.
*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
WARNING
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.
WARNING
By altitudes above 2 km, please contact
Danfoss Drives regarding PELV.

NOTICE
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.
1.1.5 Safety Regulations
•The VLT DriveMotor (FC motor) must be discon-
nected from mains if repair work is to be carried
out.
Check that the mains supply has been discon-
nected and that the necessary time has passed (4
minutes).
•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 4.1.2
Earth Leakage Current .
•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.
1.1.6 Warning against Unintended Start
•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, these stop functions are not sufficient.
•While parameters are being changed, the motor
may start.
•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.
1.2 Introduction
Specific technical publications on the FCM 300 series:

1.3 Product Concept
1.3.1 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 2.2.4 Dimensions ).
Installation is 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.

2.1.6 Protection
•Thermal overload protection of motor and
electronics.
•Monitoring of the intermediate circuit voltage
ensures that the inverter cuts out if the
intermediate circuit voltage gets too high or too
low.
•If a mains phase is missing, the inverter will cut
out when a load is placed on the motor.

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

2.2.2 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 by hand,
one quarter of a revolution, at weekly intervals. Bearings
are despatched from the works fully charged with lithium
based grease.
