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

1.1.4 About this Manual
This manual is for both instructional and for reference purposes. This manual can also serve as a guideline 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.

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"
2.1.5 Drive Parameters
The following parameters may need to be manually set for each drive in the Metasys N2 network. Refer to the Installation, Operation and Maintenance Manual
for the frequency converter for programming.
