•= Please use the interface only when the ambient temperature of the inverter unit into
which the interface is installed is within the following specified temperature limits:
Operation
: -10 ∼ +40°C (+14 ∼ +104°F)
Storage
: -25 ∼ +65°C (-13 ∼ +149°F)
•= Avoid installation locations that may be subjected to large shocks or vibrations.
•= Avoid installation locations that may be subjected to rapid changes in temperature or
humidity.
Operating Environment
Operating EnvironmentOperating Environment
Operating Environment
•= Do not touch charged parts such as the terminal block while the inverter’s CHARGE
lamp is lit. A charge will still be present in the inverter unit’s internal electrolytic
capacitors, and therefore touching these areas may result in an electrical shock.
Always turn all inverter input power supplies OFF, and wait at least 5 minutes after the
CHARGE lamp has gone out before connecting communication cables or motor wiring.
•= When installing the interface board into the inverter and making wiring connections,
make certain that no clippings or wiring leads that could cause device failure fall into
the inverter or onto electronic components.
•= Proper ground connections are vital for both safety and signal reliability reasons. For
proper grounding procedures, please refer to the section in this manual pertaining to
grounding (section 3).
•= Route the communication cables separate from the inverter input/output power wiring.
•= To avoid the possibility of electric shock due to leakage currents, always ground the
inverter unit’s E/GND terminal and the motor. To avoid misoperation, do not connect
the Profibus interface board's shield terminal to either of the above-mentioned grounds
or any other power ground.

•= The inverter’s EEPROM has a life span of 10,000 write cycles. Do not write to the
same parameter register more than 10,000 times.
•= Do not touch or insert a rod or any other item into the inverter while power is applied,
as this may lead to electrical shock or inverter damage.
•= Commission the disposal of the interface board to a specialist.
•= Do not assign the same address to more than one inverter in the same network.
•= Individual slave addresses can be set from 0 ∼ 125. Addresses 126 and above are
invalid, and will cause the inverter to trip "OPTION PCB ERROR".
•= When the inverter’s control power supply is turned on, the inverter performs
initialization functions for approximately 2 seconds, during which communications
capabilities are disabled. Communications capabilities will also be disabled for
approximately 2 seconds after momentary control power supply outages or inverter
resets.

The Profibus Communications Option ROM enclosed with the Profibus kit is
compatible only with G3 inverters with V120 or later main soft ware. An er r o r will
occur if the option ROM is installed in an inverter with pre-V120 main software. The
main software version number is printed on the CPU package (IC1) on the control
board. Additionally, this version number can be read from inverter memory by
displaying the parameter CPU VERSION in GROUP:UTILITY PARAMETERS. If you
are unsure of the software version of your inverter, please contact Toshiba
International Corporation for more information.
The Profibus option ROM version number is printed on the label attached to the
ROM. The option ROM version number can also be read from t he invert er ’s memory
and displayed on the LCD panel after initialization by displaying the parameter ROM
VERSION in GROUP:UTILITY PARAMETERS. The opt ion RO M version number
replaces the standard ROM version number after installation/initialization.
IMPORTANT NOTE: The option ROM included with the Profibus interface k it
is for installation into G3 230V/ 460V unit s only
. Do not install the option ROM into
any other inverter unit (such as H3, E3, or G 3 600V unit s ) . All inverter units other
than the G3 230V/460V series are shipped from the factory with full communications
capability, and installation of the option ROM may cause incorrect oper at ion or
inverter damage.
Please note that due to internal mechanical clearances, not all Pr ofibus connectors
can be used on all inverter units. Ensure that the Profibus connector that you plan on
using does not come into contact with any of the drive’s internal com ponents, circuit
boards or brackets. Toshiba has det er m ined t hat connectors such as the ERNI
103648 (non-terminated) and 103649 (ter m inat ed) will work for all installations. If you
have difficulty locating a connector which will work properly in your unit, please
contact Toshiba International Corpor at ion for assistance.
Additionally, certain drive models require a modified panel support bracket to allow
installation of the Prof ibus interface. Specifically, all G3 460v 10HP through 50HP
and 230v 7.5HP through 25HP units require a m odified panel support bracket. To
obtain this support bracket, contact your local distributor or Toshiba Internat ional
Corporation.

Grounding
GroundingGrounding
Grounding
Grounding is of particular im portance for reliable, stable operation. Communication
system characteristics may vary from system to system, depending on the system
environment and grounding method used. The Profibus interface card is pr ovided
with a plated SHIELD connection point by CN1, on the lower right-hand side of the
board. This SHIELD connection point is directly connected to the metallic housing of
the DB9 connector, which should then be connected to the shield of t he Profibus
network cable through the Profibus connector. To ground the network cable shield,
therefore, connect a wire with lug terminal t o this SHIELD point, and then connect the
other end of the wire to an appropriate g r ound. For specific details and requirements
regarding protective gr ounding and the Profibus network, refer to the Profibus
Standard (DIN 19245, part 1).
Please be sure to consider the following points f or m aking proper ground
connections:
Grounding method checkpoints
1. Make all ground connections such that no ground current flows through the
inverter case.
2. Ensure that all grounds are connected to points that are at the same pot ential as
inverter grounds.
3. Do not connect the Profibus interface board's SHIELD connection point to a
power ground or any other potential noise-producing ground connection (such as
the inverter's E/GND terminal).
4. Do not make connections to unstable grounds (paint-coated screw heads,
grounds that are subjected to induct ive noise, etc. )

Maintenance And Inspection
Preventive maintenance and inspection is required to maint ain t he Pr ofibus
communication interface in its opt im al condition, and to ensure a long operational
lifetime. Depending on usag e and oper at ing conditions, perform a periodic
inspection once every three to six months. Before starting inspections, always turn
off all power supplies to the inverter unit , and wait at least five minutes after the
inverter’s “CHARGE” lamp has gone out .
DANGER! Do not touch any internal parts with power applied
to the inverter, or for at least 5 minutes after power to the inverter has been
removed. A hazard exists temporarily for electrical shock even if the source
power has been removed.
Inspection Points
•= Check that the network connector screws are not loose. Tighten if necessary.
•= Check that there are no def ect s in any att ached grounding wire terminal crimp
points. Visually check that the crimp points ar e not scar red by overheating.
•= Visually check the wiring and cables for damage.
•= Clean off any accumulated dust and dirt. Place special emphasis on cleaning the
ventilation ports of the inverter and all inst alled PCBs. Always keep t hese ar eas
clean, as adherence of dust and dirt can cause premature component failure.
•= If use of the inverter unit is discontinued for extended periods of time, turn the
power on at least once every two years and confirm that the unit still f unctions
properly.
•= Do not perform hi-pot t est s on t he invert er or Profibus interface board, as t hey

Note:
Although the INVERTER ID NUMBER parameter can be set from 0 to 255,
the allowable Profibus slave addresses range only from 0 to 125. Therefore,
if this parameter is set t o a value from 126 to 255, the Profibus inter face card
will trip “OPTION PCB ERROR” upon initialization. To correct this error, set
the INVERTER ID NUMBER parameter to a value fr om 0 to 125.
To implement any parameter changes in GROUP:COMMUNICATION SETTING
PARAMETERS, the drive must be reset after m aking the changes.
If the drive into which a Profibus communications interface board is installed trips
“OPTION PCB ERROR” for any reason during init ialization or operation (for example,
if it becomes loose from it s m ounting connections), it is incapable of being r eset via
the Profibus network. When this trip condition occurs, t her efore, the drive can only
be reset locally via the panel or control terminal block.
If drive control (f r equency command input, RUN/STOP, etc.) is to be performed via
the Profibus network, the following inverter parameters must also be set as shown:

Feature Summary
Feature SummaryFeature Summary
Feature Summary
The Toshiba Profibus-DP interface provides a wide array of network data access and
drive control features. Combined with the flexible configuration and high-speed data
transfer capabilities of the Profibus network, this allows powerful networked cont rol
and monitoring systems to be designed. Som e of the main features provided in the
G3 Profibus-DP interface which allow for this control and configurabilit y are briefly
described here:
Protocol
Profibus DP (Decentralized Periphery). The int er face can also co-exist
simultaneously on networks using Profibus- FMS.
Network Baud Rates
Supports all Profibus baud rates from 9.6kbaud to 12Mbaud. The network baud rate
is automatically detected and continuously monitored during operation; no parameter
settings are necessary.
Global Control Functions
•= Freeze mode
: Input (monitor) data values are held constant at the drive until the
next “freeze” command or an “unf r eeze” com m and is r eceived.
Used primarily for synchronized monitoring of multiple Profibus
nodes.
•= Sync mode
: Output (control) data values are held const ant at the drive until the
next “sync” command or an “unsync” command is received. Used
primarily for synchronized control of m u lt iple Pr ofibus nodes.
•= Clear_Data
: All output (control) dat a values are clear ed to “0”.
Address Change Functions
Set_slave_address function supported – allows modification of the drive’s INVERTER
ID NUMBER parameter . The INVERTER ID NUMBER parameter can also be
changed while in the DATA_EXCHANGE state by accessing paramet er register 204
(hex). Refer to sections 10 and 11 of this document for more infor m ation on
accessing parameter registers.
Network Watchdog
A network watchdog function is always operating within the interface – in the event of
a disconnection from the network or loss of the network master, the inter face will
automatically stop the drive for saf ety (note that either the COMMAND MODE
SELECTION or FREQUENCY MODE SELECTION parameter must be set to 3 ( net work
control) in order for the drive to stop when a watchdog time-out occurs).
