1 Overview
1.1.1 Software Version
VLT HVAC Drive
FC 102 Series
Software version: 3.4x
and VLT AQUA Drive FC 202 Series
Software version: 1.7x
This guide can be used with all VLT HVAC Drive frequency converters with
software version 3.4x and VLT AQUA Drive frequency converters with
software version 1.7x.
The actual software version number can be read from
par. 15-43 Software Version.
1.1.2 Introduction
The frequency converter control board is program selectable
for use with the Johnson Controls Metasys N2 protocol.
Metasys N2 is a master/slave control network. The physical
layer is RS-485 compatible, half duplex 9600 baud shielded
twisted pair. The N2 software protocol is designed to be
general in nature to accommodate the unique properties each
device type may have. Every device connection to the N2
network can be thought of as a small data manager. Data
points in the database are classified as analog I/O (floating
point), binary I/O or integer data points - floats, integers or
bytes. Each data type has its own unique structure defined in
the Metasys N2 system Protocol Specification for Vendors.
The information in this manual is intended to provide you with
comprehensive information on how to install and set up the
frequency converter for communication over a Metasys
network.
For specific information on operation of the drive, refer to the
VLT HVAC Drive Operating Instructions, MG.11.Ax.yy or the VLT
AQUA Drive Operating Instructions, MG.20.Mx.yy.
1.1.3 About this Manual
This manual is for both instructional and for reference
purposes. This manual can also serve as aguideline when you
specify and optimize your communication system.
It is highly recommended that you read this manual in its
entirety before initiating any programming. It is assumed that
the user has full knowledge of the capabilities and limitation
of the controller node in addition to full knowledge of the
frequency converter.
1.1.4 References
In addition to this manual, the following two manuals should
be consulted: VLT HVAC Drive Operating Instructions, MG.
11.Ax.yy, VLT AQUA Drive Operating Instructions, MG.20.Mx.yy
and Johnson Controls METASYS N2 System Protocol Specification

2.1.2 Network Connection
Connect signal wires to terminal 68 (N+) and terminal 69 (N-)
on main control board of the drive. If shielded cabling is used,
connect one end of the shield to terminal 61. This terminal is
connected to ground via an internal RC link. It is highly
recommended to use shielded twisted-pair cables to reduce
the differential mode interference between the conductors.
Danfoss do not take any responsibility for consequences, if
unshielded or untwisted cables are used.
Torque Specifications: 4.5 in.lb. (0.5 Nm) if screw terminal is used
Control wire: 18 - 24 AWG, shielded, twisted pair
2.1.3 Hardware Set-up
RS-485 Bus Connection:
One or more frequency converters can be connected to a
control (or master) using the RS-485 standardized interface.
Terminal 68 is connected to the P signal (TX+, RX+), while
terminal 69 is connected to the Nsignal (TX-,RX-). If more than
one frequency converter is connected to amaster, use parallel
connections.

NOTE
The factory setting for the dip switch is OFF.
In order to avoid potential equalizing currents in the screen,
earth the cable screen via terminal 61, which is connected to
the frame via an RC-link.
Bus termination: The RS-485 bus must be terminated by a
resistor network at both ends. For this purpose, set switch
S801 on the control card to "ON". For more information, see
the paragraph: Switches S201, S202 and S801.

2.1.4 Error Codes
Error Code 00 is issued after power up or after a time out where all overridden points were released, as long as no Identify yourself
command has been issued by the master.
Error Code 01 is issued if the command is not supported or not known by the drive.
Error Code 02 is issued if the received telegram has a checksum error.
Error Code 03 is issued if the N2 telegram receive buffer exceeds 256 characters.
Error Code 05 is issued if the received N2 telegram is too long.
Error Code 10 is issued the data is out of expected range
Error Code 11 is issued when:
1. A point attributes or attribute bit is unused.
2. A point attributes or attribute bit is for JCI use only.
3. An internal data point attribute for current value can not be changed while running
Error Code 12 is issued when:
1. The N2 master tries to change attribute 2 bit 6 "Current State" on a BO and the drive is tripped.
2. The N2 master tries to change attribute 2bit 6"Current State" on aBO and the drive is trip locked except for BO 5

Table 2.1: Reference/feedback values
The reference/feedback value is the percentage of the range
of parameter 3-02 and 3-03. Values within the ranges 100% to
200% and -200% to -100% applies only to the reference. The
Float representation of the value 200% must be limited to
maximum 32767 and minimum -32768.
2.2.3 Status Update Request
A Status Update Request will cause the drive to report its
current operating status. The status codes, descriptions and
associated alarms are shown in the chart below.
The Device Status Code consists of two parts. The Least Signif-
icant Byte, (LSB) of the hex number is the Alarm Number. The
Most Significant Byte (MSB) indicates if the alarm is a normal
trip (01) that can be reset automatically or manually, or if the
alarm is a trip lock (02) requiring cycling power to the drive.

Read/write notes
A write command to an ADF (Internal Floating Point) or BD
(Internal Byte) point type will be stored in the drive's EEPROM.
NOTE
If write command is issued to an overridden point, the
new value will not be stored in the drive's EEPROM.

2.2.4 Override/Override Release Commands
and Time Out, 8-04 (Setting [20], N2
Override release)
The way the overridden points are released is very important
to the way the drive will behave during the override release
time out or for release commands issued by the N2 master.
This is due to the fact that the active setup can be changed to
adifferent setup. If one would release the active setup before
the values that have been overridden in that setup, the
backup values would then be restored to the wrong setup,
leaving the overridden values in the old setup unchanged.
The release after override time out:
During an override release time-out, all points which are
overridden, will be released in the order, which they are
specified in Appendix POINTMAP:
1. Release Analog Outputs from point address (NPA) 0
to 255.
2. Release Binary Outputs from point address (NPA) 0
to 255.
3. Release Internal Floating Points from point address
(NPA) 0 to 255.
4. Release Internal Integer Points from point address
(NPA) 0 to 255.
5. Release Internal Byte points from point address
(NPA) 0 to 255.
2.2.5 Change of State (COS)/POLLING
A change of state occurs when a new command has been
issued for the drive. This command can be issued through the
bus or through adrive related status change or command. The
master can issue a series of poll commands to the network
devices to get an update on any status changes from the time
of the last polling. When polling afrequency converter for the
first time after a network has been powered up after an F
command has been issued, a 0/4 poll command must be
issued.
2.2.6 Handling of Poll Message Commands
The Identity Command will cause the drive to report all AI, AO,
BI and BO points, which are available when the next Poll (0/4)
is received. The drive also supports COS for AI and BI point
types. The drive is limited to responding with up to 200 ASCII
characters, so multiple messages may need to be sent before
all available points have been reported.
Upon receiving the Poll (0/4), the frequency converter will
begin exporting the requested information. The frequency
converter will continue to export new information upon
receiving the 0/5 Poll until it has sent all requested informa-
tion. Then it will respond to a new 0/5 Poll with an ACK
response to indicate all information has been transmitted and
complete the Poll sequence receiving a 0/4 Poll before
sending the ACK response will cause the frequency converter
to re-transmit its latest response.
The drawing below illustrates the AI COS handling.

For AI:
Alarm Enable or Warning Enable must be set in the Object
Configuration Attribute (Attribute 1). Low/High Alarm limits
(Attribute 8, 11) or Low/High Warning limits (Attribute 9, 10)
must be programmed. Differential Value (Attribute 12) must
also be programmed.
For BI:
Alarm Enable must be set in the Object Configuration Attrib-
ute (Attribute 1).
Normal state must be programmed in the Object Configura-
tion Attribute (Attribute 1)
Att XX =Attribute number, HA =High alarm, LA =Low alarm,
HW = High Warning, LW = Low Warning
The AI COS alarms will only be cleared when the point value
goes below the high alarm/warning or above the low alarm/
warning limit by more than the programmed differential value
(Attribute 12).
The BI COS will set the Alarm (Object Status bit 4) if COS
enabled (Object Configuration Bit 0) is set, Alarm Enabled
(Object configuration bit 3) is set, and Current State (Object
Status bit 6) is different from Normal State (Object Configura-
tion bit 1).
