1Overview
1.1.1 Software Version
AF-600 FP
Software version: 2.12
This guide can be used with all AF-600 FP frequency converters with
software version 2.12 or later
The actual software version number can be read from
par. ID-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 N2is a master/slave control network.
The physical layer is RS485 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 AF-600 FP Operating Instructions

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 twisted-pair cables to reduce the differential mode
interference between the conductors
Torque Specifications: 4.5 in.lb. (0.5 Nm)
Control wire: 18 - 24 AWG, shielded, twisted pair

2.1.3 Hardware Set-up
RS485 Network Connection:
One or more frequency converters can be connected to a control (or master) using the RS485 standardized interface. Terminal 68 is connected to the P signal (TX
+, RX+), while terminal 69 is connected to the N signal (TX-,RX-). If more than one frequency converter is connected to a master, use parallel connections.
Illustration 2.1: Network termination switch
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.
Network termination: The RS485 network 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.
NB!
Communication protocol must be set to Drive MC par. O-30.

2.1.4 Error Codes
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 message has a checksum error.
Error Code 03 is issued if the N2 message receive buffer exceeds 256 characters.
Error Code 05 is issued if the received N2 message 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 2 bit 6 "Current State" on a BO and the drive is trip locked except for BO 5 "reset"

Table 2.11: Reference/feedback values
The reference/feedback value is the percentage of the range of parameter F-52 and F-53. 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 Significant 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.
NB!
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, O-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 a different 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 a drive 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 a frequency 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 information. 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.
