Introduction
Thank you for purchasing a Vector-control General-purpose VS-606V7 Inverter and a SI-T/
V7 MECHATROLINK-I/MECHATROLINK-II Communications Interface Unit (called “SI-
T/V7 Unit” below).
This manual describes the operation and specifications of the SI-T/V7 Unit, which connects
to the MECHATROLINK-I/MECHATROLINK-II open field network for exchanging data.
Be sure that you have read and understood this manual before attempting to operate the SI-
T/V7 Unit.
For details on operating the Inverter itself, refer to the VS-606V7 Series Instruction Manual
(TOE-S606-11).

1Overview
The SI-T/V7 Interface Unit is an interface unit that connects to the MECHATROLINK-I or
MECHATROLINK-II high-speed field network for communicating with the host controller.
By installing the SI-T/V7 Unit to a VS-606V7-series Inverter, various applications are enabled;
monitoring of the run/stop status and the operating conditions as well as the changing and the
referencing of the settings for the Inverter constants from the host controller.
The SI-T/V7 Unit can be installed in the following Inverters.
• VS-606V7-series Inverter, software No. 5650.
• VS-606V7-series Inverter, software No. 573X.
Note: 1. “X” indicates the design revision order.
2. The Inverter software will soon be updated from version No. 5650
to No. 573X.
VS-606V7 Inverter with an SI-T/V7 Unit does not conform to CE Marking, although the VS-606V7
Inverter itself conforms to CE Marking.

4 Installation and Wiring
Route the MECHATROLINK communications cables separately from the main circuit wiring and
other power lines.
4.1 Installing the SI-T/V7 Unit
Use the following procedure to mount the SI-T/V7 Unit after removing the Inverter’s Digital
Operator and front cover.
Be sure to complete the wiring to the Inverter before installing the SI-T/V7 Unit, because the
terminals of the Inverter are hidden from view after the Unit is installed.
1. Turn OFF the Inverter’s main-circuit power supply and wait one minute.
2. Confirm that all the indicators on the Inverter have turned OFF, wait until the specified
period of time has elapsed (the time is shown on the Inverter’s front cover), and then
remove the Digital Operator and the front cover.
3. Use nippers to cut off the cover of the Inverter’s CN2 connector in the three places-
marked as A in Fig. 1. Be careful that the covers do not fall into the Inverter Unit. If
pieces do fall in, be sure to remove them.
4. Align the mounting fixture with the C tab, and use M3 ×8 SW screws to secure the fix-
ture B.
5. Before installing the SI-T/V7 Unit on the Inverter, connect the grounding cable to the
grounding terminal as shown in Fig. 2 . Three types of grounding cables for various
Inverter capacities are provided. Connect the appropriate cable with a crimp terminal.
6. When installing the SI-T/V7 Unit onto the Inverter Unit, make sure that it is straight.
Align the modular plug (CN10) of the SI-T/V7 Unit with the modular plug (CN1) of the
Inverter, and connector (CN2) with the connector for the SI-T/V7 Unit (CN2).
7. Tighten the screw at position D to affix the SI-T/V7 Unit to the Inverter Unit. The screw
is already screwed in on the Inverter Unit.
8. Return the Digital Operator and the front cover to their original positions.
• Before installing or removing the Option Unit, or performing wiring operations, always turn OFF the
power to the Inverter and wait until the specified period of time has elapsed after all the Inverter
indicators have turned OFF. (The time is shown on the Inverter’s front cover.)
Failure to do so can result in electric shock.

4.2 MECHATROLINK Communications Cables
Wiring
Wire the MECHATROLINK communications cables to the communications connector
(CN2).
• For communications cables, use special shielded twisted-pair cables for MECHATROLINK com-
munications.
Recommended cable: JEPMC-W603- *
*  is the length (m).
With USB male connector
• Install MECHATROLINK communications cables apart from main-circuit wiring and other elec-
trical and power lines.
• Connect the terminator (model No.: JEPMC-W6022) on the end of the communication lines.
• Maximum transmission distance is 50 m.
• Minimum wiring distance between stations is 0.5 m.

6 Communications Specifications
* 1. The baud rate is 4 Mbps for MECHATROLINK-I, and 10 Mbps for
MECHATROLINK-II.
* 2. For MECHATROLINK-I, a cycle is 2 ms. For MECHATROLINK-II, a
cycle is 1 ms to 8 ms for a 32-byte data transmission, and 500 µs to 8
ms for a 17-byte data transmission.
* 3. For MECHATROLINK-I, only a 17-byte data transmission can be
selected.
* 4. The maximum number of connectable stations changes depending on
the types and settings of the host controller, baud rate, or communica-
tions cycle. For details, refer to the manuals of your controller.
Communications cycle: Integral multiple of transmission cycles
(depending on the host controller settings).
Example: If the host controller is an MP2300
• For MECHATROLINK-II (32-byte transmission,
2-ms communications cycle): 21 stations max. (21 slaves can be
set, but then the maximum number of connectable Inverters will
be 16.)
