Usage Precautions
•Proper ground connections are vital for both safety and signal
reliability reasons. Ensure that all electrical equipment is properly
grounded.
•Route all communication cables separate from high-voltage or noise-
emitting cabling (such as ASD input/output power wiring).
Installation and Wiring
•Do not touch charged parts of the drive such as the terminal block
while the drive’s CHARGE lamp is lit. A charge will still be present in
the drive’s internal electrolytic capacitors, and therefore touching these
areas may result in an electrical shock. Always turn all drive input
power supplies OFF, and wait at least 5 minutes after the CHARGE
lamp has gone out before connecting communication cables.
•Internal drive EEPROMs have a limited life span of write cycles.
Observe all precautions contained in this manual and your ASD
manual regarding which drive registers safely may and may not be
repetitively written to.
•For further drive-specific precaution, safety and installation
information, please refer to the appropriate documentation supplied
with your drive.

1. Feature Summary
Primary Network
Half-duplex RS-485 (A / B / Signal Ground / Shield).
Supported Protocols
•Schneider Electric Modbus RTU
•Johnson Controls Metasys N2
•Siemens Building Technologies FLN
User-Selectable Register Processing
Four user-selectable registers can be designated for special processing. The
use of these registers is protocol-dependent.
Register Remapping
The Modbus RTU protocol allows all ASD parameters numbered FA00 - FFFF
to be accessible as Modbus holding registers both at 0xFA00 – 0xFFFF
(64000
10
– 65535
10
) as well as 0x0A00 - 0x0FFF (2560
10
– 4095
10
). This
allows master devices that can index only 9999 total holding registers to
access all available ASD information.
Selectable Network Timeout Processing
An optional 1s-255s network timeout time can be selected. If a timeout setting
is selected, then after the designated period of network inactivity the interface
will perform actions to place the drive in a “failsafe” state. The specific action
taken is protocol-dependent.

2. Installing the Interface
The ASD-NANOCOM interface has been designed for quick and simple
installation. The card is connected to the drive’s control board via two 2x13-pin
connectors. No additional mechanical support is required, and the only tool
required for installation is a small flat screwdriver for wiring the network cable
to the drive’s RS-485 pluggable terminal block.
Installation of the interface should only be performed by a qualified technician
familiar with the maintenance and operation of the ASD in which the interface
is installed. To install the ASD-NANOCOM, complete the following steps:
1.
CAUTION!
Verify that all input power sources to the drive
have been turned OFF and are locked and tagged out.
2.
DANGER!
Wait at least 5 minutes for the drive’s
electrolytic capacitors to discharge before proceeding to the next step. Do
not touch any internal parts with power applied to the drive, or for at
least 5 minutes after power to the drive has been removed. A hazard
exists temporarily for electrical shock even if the source power has
been removed. Verify that the CHARGE LED has gone out before
continuing the installation process.
3. Remove the drive’s front cover / open the drive’s cabinet door (refer to the
appropriate drive manual for instructions on how to do this). Take care not
to damage or dislodge the keypad-to-drive cable connection.
4. Refer to Figure 1 for an overview of the drive’s control board with relevant
ASD-NANOCOM interface sections indicated. The Q7 ASD comes from
the factory with a small jumper board (Toshiba part #55365A) installed in
the J4 connector. Remove this jumper board.
5. Insert the ASD-NANOCOM interface into the drive control board’s J4/J5
connectors. Pay particular attention to the interface’s orientation, as
there is no keying to prevent it from inadvertently being installed
upside down. The header labeled “J4” on the back of the interface must
plug into the connector labeled “J4” on the drive’s control board, and
similarly the “J5” header must plug into the “J5” connector. When properly
mounted, the small 10-pin surface mount header on the top side of the
interface will be located in the lower left-hand corner. Refer to Figure 2 for
a detailed view of a correct installation. Confirm that the interface is fully
seated in the J4/J5 connectors.
6. Place both duplex selection jumpers (refer to Figure 1) on the drive’s
control board in the “HALF” position. Refer to Figure 3 for a detailed view
of correctly-positioned duplex selection jumpers.

7. Connect the RS-485 network cable to the 4-position pluggable terminal
block on the drive’s control board labeled CN3 (refer to Figure 1 and
Figure 3.) Refer to section 3 of this manual for detailed network
connection information. Ensure that the terminal block is fully seated into
the terminal block header, and route the network cable such that it is
located well away from any drive input power or motor wiring. Also take
care to route the cable away from any sharp edges or positions where it
may be pinched.
8. Take a moment to verify that the ASD-NANOCOM interface is fully seated
in the drive control board’s J4/J5 connectors, that the duplex selection
jumpers are both in the “HALF” position, that the network cables are
properly terminated in CN3, that CN3 is fully seated in its header, and that
the RS-485 network cable has sufficient clearance from the drive’s input
power and output motor wiring. Refer to Figure 4.
9. Reinstall the drive’s front cover / close the drive’s cabinet door.
10. Turn the power source to the drive ON, and verify that the drive functions
properly. If the drive does not appear to power up, or does not function
properly, immediately turn power OFF. Repeat steps 1 and 2 to remove
all power from the drive. Then, verify all connections. Contact ICC or
your local Toshiba representative for assistance if the problem persists.

3. RS-485 Connections
Figure 5 indicates the specific network connections to the RS-485 pluggable
terminal block (CN3). In general, there is no universal standardized labeling
scheme for RS-485 signal connections, so other equipment on your network
may use labels such as “+” and “-“ or “S1” and “S2”, etc. In such instances,
the correct connection scheme is usually intuitive (e.g. in FLN installations,
connection “+” to “A” and “-“ to “B”), or typically can be obtained via trial and
error by simply swapping the signal wires if no connection can be achieved.
Note that the “Shield” terminal has no internal connection: its purpose is simply
to provide a network cable shield chaining location between devices. The
shield is then typically connected to ground at one location only.

5. Maintenance and Inspection
Preventive maintenance and inspection is required to maintain the interface in
its optimal condition, and to ensure a long operational lifetime. Depending on
usage and operating conditions, perform a periodic inspection once every
three to six months. Before starting inspections, always turn off all power
supplies to the drive, and wait at least five minutes after the drive’s “CHARGE”
lamp has gone out.
Inspection Points
•Verify that the interface is fully seated in the drive control board’s J4/J5
connectors.
•Confirm that the RS-485 network cable is still properly terminated in CN3.
Re-terminate if necessary.
•Check that there are no defects in any attached wire terminal crimp points.
Visually check that the crimp points are not scarred by overheating.
•Check that the CN3 pluggable terminal block is fully seated in its header.
Reseat if necessary.
•Visually check all wiring and cables for damage. Replace as necessary.
•Clean off any accumulated dust and dirt.
Please pay close attention to all periodic inspection points and maintain a good
operating environment.

6. Storage and Warranty
6.1 Storage
Observe the following points when the interface is not used immediately after
purchase or when it is not used for an extended period of time.
•Avoid storing the unit in places that are hot or humid, or that contain large
quantities of dust or metallic dust. Store the unit in a well-ventilated
location.
•When not using the unit for an extended period of time, apply power at
least once every two years and confirm that it still functions properly.
6.2 Warranty
The interface is covered under warranty by ICC, Inc. for a period of 12 months
from the date of installation, but not to exceed 18 months from the date of
shipment from the factory. For further warranty or service information, please
contact Industrial Control Communications, Inc. or your local distributor.

7. Network Configuration Parameters
Because the ASD-NANOCOM interface supports several different protocols,
some amount of configuration must be performed prior to inclusion on the
chosen network. This configuration is performed by setting certain drive
parameters, some of which dictate the characteristics of the network
communication, and some of which serve to facilitate the transfer of data
between the drive’s control board and the interface itself.
Throughout this section, take special note that the values of parameters
in the Program…Comm Settings group are only validated upon drive
power-up initialization. Therefore, if any of these parameters are changed,
be sure to cycle the drive’s incoming power to validate the changes.
7.1 Primary Parameter Settings
The primary parameters are used by the ASD-NANOCOM interface to
configure itself on the RS-485 network. These parameters are located in the
Program…Comm Settings group, and are as follows:
ASD Number
Ext Comm Cfg #1
Ext Comm Cfg #2
Ext Comm Cfg #3
Ext Comm Cfg #4
Ext Comm Cfg #5
Ext Comm Cfg #6
Ext Comm Cfg #7
Ext Comm Cfg #8
These parameters are used as follows:
ASD Number: Sets the drive’s station number on the network. Although this
parameter is adjustable from 0-255, not every value is a valid entry. Refer to
the protocol-specific sections of this manual (sections 8 through 10) for details
pertaining to the allowable station number assignment range for each
supported protocol.
Ext Comm Cfg #1: Selects the RS-485 protocol. Allowable values are:
Modbus RTU............ 0
Metasys N2.............. 1
Siemens FLN........... 2
All other values will result in an INVALID PROTOCOL error indication (refer to
Ext Comm Cfg #4).
16
Ext Comm Cfg #2: Selects the Modbus RTU network characteristics (baud
rate, parity and stop bits). Refer to section 8 for more information.
Ext Comm Cfg #3: Defines an optional network timeout timer. Allowable
values are as follows:
0.............timer disabled
1-255 .....1s-255s timer selected
If the network timer is disabled, then no special processing will occur based on
the interval between received network packets: the interface will simply
continue to wait for the next incoming packet that it may take action on.
Upon initial power-up and after each timeout occurrence, the network timer will
not start until a complete packet has been received by the interface and
responded to. Once started, a complete packet must be received within the
timeout time setting to prevent the timer from expiring. As the timeout timer is
principally intended to monitor network health, received packets do not need to
be directed at any specific interface: even if an interface detects a packet
intended for a different interface on the network, it will consider the network
“healthy” and therefore reset its timeout timer.
The resultant behavior when a network timeout occurs is protocol-dependent.
Refer to the sections of this manual pertaining to the specific protocols for
further details.
Ext Comm Cfg #4: This parameter is a read-only error code. If the ASD-
NANOCOM interface experiences any fatal errors during initial configuration or
operation, then this parameter can be inspected to determine the specific error
code to aid in troubleshooting the problem. An example of a fatal error would
be if the Modbus RTU protocol is selected but the ASD Number parameter is
set to 0. A list of possible error codes is provided in Table 1.
Table 1: ASD-NANOCOM Error Codes
Error Code Meaning
0 NO ERROR (normal operation)
1 INVALID EQUIPMENT
2 INVALID PROTOCOL
3 INVALID ADDRESS
4 INVALID NETWORK SETTINGS
5 RESOURCE ALLOCATION ERROR
17
Ext Comm Cfg #5 ∼
∼∼
∼Ext Comm Cfg #8: These four parameters designate
user-selectable drive parameter numbers for special processing. Their use is
different for each protocol, so refer to the protocol-specific sections of this
manual for further details.
7.2 Additional Parameter Settings
Although the drive parameters outlined in section 7.1 provide the majority of
the RS-485 network configuration, there are several other communication-
related parameters that must be set appropriately to ensure reliable
communication between the drive and the ASD-NANOCOM interface itself.
Verify that the following parameters in Program…Comm Settings are set as
indicated:
RS485 Baud Rate ......... Although any setting will work properly, it is
recommended to set this value to 38400. This
setting will provide the maximum bandwidth
utilization between the drive and the ASD-
NANOCOM interface.
485 Timeout Time ....... Set to 0s.
RS485 Res Time............ Set to 0.00s.
RS485 Master Out ....... Set to Normal.
7.3 Controlling the Drive from the Network
If drive control (frequency command input, RUN/STOP, etc.) is to be performed
via the RS-485 network, then the following ASD parameters in
Program…Utility Group must also be set as shown:
Command Mode................ set to ”RS232/485”
Frequency Mode............ set to ”Use RS232/485”
As an alternative to setting the Command Mode and Frequency Mode
selection parameters, the override (priority) bits may be activated in the RS-
485 command word (parameter FA04) instead. The specific method of
activating these bits depends on the protocol being used. For more
information on the proper use of the override bits, refer to the appropriate
Toshiba documentation regarding the drive’s command mode and frequency
mode control hierarchy.

8. Modbus RTU Details
8.1 Node Addressing
ASD parameter ASD Number selects the Modbus node address. Valid
addresses are 1 – 247. NOTE that the factory default value for ASD Number
is 0, and must therefore be changed to a valid Modbus node address, or an
INVALID ADDRESS error indication will result.
8.2 Network Characteristics
ASD parameter Ext Comm Cfg #2 selects the Modbus RTU network
characteristics (baud rate, parity and stop bits). Refer to Table 2 to determine
the association between this parameter’s value and the resultant network
characteristics.
Table 2: Modbus Network Configuration
Parameter Value Baud Rate Parity Stop Bits
0 2400 Odd 1
1 2400 Even 1
2 2400 None 1
3 4800 Odd 1
4 4800 Even 1
5 4800 None 1
6 9600 Odd 1
7 9600 Even 1
8 9600 None 1
9 19200 Odd 1
10 19200 Even 1
11 19200 None 1
12 38400 Odd 1
13 38400 Even 1
14 38400 None 1
15 2400 None 2
16 4800 None 2
17 9600 None 2
18 19200 None 2
19 38400 None 2
Any other value for Ext Comm Cfg #2 will result in an INVALID NETWORK
SETTINGS error indication.
19
Note that the Modbus network characteristics indicated in Table 2 are
unrelated to the ASD parameters RS485 Baud Rate and Parity. The
RS485 Baud Rate and Parity parameters affect only the communication
between the drive’s control board CPU and the ASD-NANOCOM interface.
8.3 Supported Functions
The interface can act as a Modbus RTU slave according to the Modicon
Modbus Protocol Reference Guide (PI-MBUS-300 Rev. J). Supported Modbus
functions are indicated in Table 3. Broadcasts (address field=0) for functions
5, 6, 15 and 16 are supported.
Table 3: Supported Modbus Functions
Function Code Function
1 Read coils
3 Read multiple registers
5 Write coil
6 Write single register
15 Force multiple coils
16 Write multiple registers
8.4 Register Addressing
To access a drive parameter, simply access the corresponding Modbus
holding register. Note that all Toshiba documentation lists drive registers in
hexadecimal (hex) format, so conversion to decimal may be required. For
example, let’s say we would like to access the drive’s “maximum frequency”
parameter. “Maximum frequency” is drive parameter 0011 (which is equivalent
to 0x0011 or 0011
16
), so converting this to decimal results in a value of 17
10
.
Therefore, accessing Modbus holding register 17 (“known as” 40017) will
access the “maximum frequency” parameter.
8.5 Register Remapping
The ASD-NANOCOM interface allows access to holding register indexes from
1
10
- 65535
10
. This directly provides access to all ASD parameters from 0001
16
– FFFF
16
. For example, the drive’s RS-485 frequency command is located at
parameter FA05 (64005
10
). However, some Modbus master devices are
capable of indexing only a maximum of 9999 holding registers (1
10
- 9999
10
or
0001
16
– 270F
16
). Directly accessing holding register 64005 in order to set a
drive frequency command would therefore not be possible from these master
