Safety
WARNING
HIGH VOLTAGE
Frequency converters contain high voltage when
connected to AC mains input power. Installation, start
up, and maintenance should be performed by qualified
personnel only. Failure to perform installation, start up,
and maintenance by qualified personnel could result in
death or serious injury.
WARNING
UNINTENDED START
When the frequency converter is connected to AC mains,
the motor may start at any time. The frequency
converter, motor, and any driven equipment must be in
operational readiness. Failure to be in operational
readiness when the frequency converter is connected to
AC mains could result in death, serious injury,
equipment, or property damage.
WARNING
DISCHARGE TIME
Frequency converters contain DC-link capacitors that can
remain charged even when the frequency converter is
not powered. To avoid electrical hazards, disconnect AC
mains, any permanent magnet type motors, and any
remote DC-link power supplies, including battery
backups, UPS and DC-link connections to other
frequency converters. Wait for the capacitors to fully
discharge before performing any service or repair work.
The amount of wait time is listed in the Discharge Time
table. Failure to wait the specified time after power has
been removed before doing service or repair could result
in death or serious injury.

1.4 Jumper Terminal 12 and 27
When using factory default programming values, jumper
wire may be required between terminal 12 and terminal 27
for the frequency converter to operate.
•Digital input terminal 27 is designed to receive an
24 V DC external interlock command. In many
applications, the user wires an external interlock
device to terminal 27
•When no interlock device is used, wire a jumper
between control terminal 12 to terminal 27. This
provides internal 24 V signal on terminal 27
•No signal present prevents the unit from
operating
1.5 Automatic Motor Adaptation (AMA)
Automatic motor adaptation (AMA)
It is highly recommended to run AMA because it measures
the electrical characteristics of the motor to optimize
compatibility between the frequency converter and the
motor under VVCplus mode.
•The frequency converter builds a mathematical
model of the motor for regulating output motor
current thus enhancing motor performance.
•Some motors may be unable to run the complete
version of the test. In that case, select Enable
reduced AMA
•If warnings or alarms occur, see 6 Warnings and
Alarms
•Run this procedure on a cold motor for best
results
To run AMA using the numeric LCP (NLCP)
1. By default parameter setting, connect terminal 12
and 27 before running AMA.
2. Enter the main menu.
3. Go to parameter group 1-** Load and Motor.
4. Press [OK].
5. Set motor parameters using name plate data for
parameter group J1-1-2* Motor Data.
6. Set motor cable length in 1-42 Motor Cable Length
7. Go to 1-29 Automatic Motor Adaptation (AMA).
8. Press [OK].
9. Select [1] Enable complete AMA.
10. Press [OK].
11. The test will run automatically and indicate when
it is complete.
NOTICE
AMA function in FC 360 does not cause the motor
to run and it does not harm the motor.

2.2 Product Overview
A frequency converter is an electronic motor controller
that converts AC mains input into a variable AC waveform
output. The frequency and voltage of the output are
regulated to control the motor speed or torque. The
frequency converter can vary the speed of the motor in
response to system feedback, such as changing
temperature or pressure for controlling fan, compressor, or
pump motors. The frequency converter can also regulate
the motor by responding to remote commands from
external controllers.
In addition, the frequency converter monitors the system
and motor status, issues warnings or alarms for fault
conditions, starts and stops the motor, optimizes energy
efficiency, and offers many more control, monitoring, and
efficiency functions. Operation and monitoring functions
are available as status indications to an outside control
system or serial communication network.
2.3 Additional Resources
Other resources are available to understand advanced
frequency converter functions and programming.
•The Programming Guide provides greater detail
on working with parameters.
•The Design Guide is intended to provide detailed
capabilities and functionality to design motor
control systems.
•Optional equipment is available that may change
some of the procedures described. Be sure to see
the instructions supplied with those options for
specific requirements.

3.2.1 General Requirements
WARNING
EQUIPMENT HAZARD!
Rotating shafts and electrical equipment can be
hazardous. Extreme care should be taken to protect
against electrical hazards when applying power to the
unit. All electrical work must conform to national and
local electrical codes and installation, start up, and
maintenance should only be performed by trained and
qualified personnel. Failure to follow these guidelines
could result in death or serious injury.
CAUTION
WIRING ISOLATION!
Run input power, motor wiring and control wiring in
three separate metallic conduits or use separated
shielded cable for high frequency noise isolation. Failure
to isolate power, motor and control wiring could result
in less than optimum frequency converter and associated
equipment performance.
Run motor cables from multiple frequency converters
separately. Induced voltage from output motor cables
run together can charge equipment capacitors even with
the equipment turned off and locked out.
•An electronically activated function within the
frequency converter provides overload protection
for the motor. The overload provides Class 20
motor protection. See 6 Warnings and Alarms for
details on the trip function.
Wire Type and Ratings
•All wiring must comply with local and national
regulations regarding cross-section and ambient
temperature requirements.
•Danfoss recommends that all power connections
be made with a minimum 75 °C rated copper
wire.
•See 8 Specifications for recommended wire sizes.
3.2.2 Earth (Grounding) Requirements
WARNING
GROUNDING HAZARD!
For operator safety, it is important to ground the
frequency converter properly by a certified electrical
installer in accordance with national and local electrical
codes as well as instructions contained within this
document. Ground currents are higher than 3.5 mA.
Failure to ground the frequency converter properly could
result in death or serious injury.
•Proper protective grounding for equipment with
ground currents higher than 3.5 mA must be
established, see 3.2.2.1 Leakage Current (>3.5 mA)
•A dedicated ground wire is required for input
power, motor power and control wiring
•Use the clamps provided with the equipment for
proper ground connections
•Do not ground one frequency converter to
another in a “daisy chain” fashion (see
Illustration 3.3)
•Keep the ground wire connections as short as
possible
•Using high-strand wire to reduce electrical noise
is recommended
•Follow motor manufacturer wiring requirements

Illustration 3.3 Grounding Principle
3.2.2.1 Leakage Current (>3.5 mA)
Follow national and local codes regarding protective
earthing of equipment with a leakage current > 3.5 mA.
The earth leakage current depends on various system
configurations including RFI filtering, screened motor
cables, and frequency converter power.
EN/IEC61800-5-1 (Power Drive System Product Standard)
requires special care if the leakage current exceeds 3.5 mA.
Earth grounding must be reinforced in one of the
following ways:
Installation VLT®AutomationDrive FC 360 Quick Guide
MG06A302 - VLT®is a registered Danfoss trademark 13
33

•Earth ground wire of at least 10 mm2(copper
wire)
•Two separate earth ground wires both complying
with the dimensioning rules
See EN 60364-5-54 § 543.7 for further information.
Using RCDs
Where residual current devices (RCDs), also known as earth
leakage circuit breakers (ELCBs), are used, comply with the
following:
•Use RCDs of type B only which are capable of
detecting AC and DC currents
•Use RCDs with an inrush delay to prevent faults
due to transient earth currents
•Dimension RCDs according to the system configu-
ration and environmental considerations
3.2.3 Mains, Motor and Earth Connections
WARNING
INDUCED VOLTAGE!
Run output motor cables from multiple frequency
converters separately. Induced voltage from output
motor cables run together can charge equipment
capacitors even with the equipment turned off and
locked out. Failure to run output motor cables separately
could result in death or serious injury.
Earthing (grounding) clamps are provided for motor wiring
(see Illustration 3.4).
•Do not install power factor correction capacitors
between the frequency converter and the motor
•Do not wire a starting or pole-changing device
between the frequency converter and the motor
•Follow motor manufacturer wiring requirements
•All frequency converters may be used with an
isolated input source as well as with ground
reference power lines. When supplied from an
isolated mains source (IT mains or floating delta)
or TT/TN-S mains with a grounded leg (grounded
delta), set 14-50 RFI Filter to OFF (size J6-J7) or
remove the RFI screw (J1-J5). When off, the
internal RFI filter capacitors between the chassis
and the intermediate circuit are isolated to avoid
damage to the intermediate circuit and to reduce
earth capacity currents in accordance with IEC
61800-3.
•Do not install switch between the frequency
converter and the motor in IT mains.

Table 3.3 Terminal Descriptions
3.2.4.3 Control Terminal Functions
Frequency converter functions are commanded by
receiving control input signals.
•Each terminal must be programmed for the
function it will be supporting in the parameters
associated with that terminal. See Table 3.3 for
terminals and associated parameters.
•It is important to confirm that the control
terminal is programmed for the correct function.
See 4 User Interface and Programming for details
on accessing parameters and for details on
programming.
•The default terminal programming is intended to
initiate frequency converter functioning in a
typical operational mode.

3.2.4.4 Using Screened Control Cables
Correct screening
The preferred method in most cases is to secure control
and serial communication cables with screening clamps
provided at both ends to ensure best possible high
frequency cable contact.
If the earth potential between the frequency converter and
the PLC is different, electric noise may occur that will
disturb the entire system. Solve this problem by fitting an
equalizing cable as close as possible to the control cable.
Minimum cable cross section: 16 mm2.
