1 Overview 1 Overview 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.
2.2 Parts List The SI-T/V7 Unit contains the following parts. Parts Name 3 Qty SI-T/V7 Communications Interface Unit 1 Mounting fixture 1 M3 × 8 SW screw 1 Grounding cable (small) 1 Grounding cable (medium) 1 Grounding cable (large) 1 Component Names and Settings 3.1 Component Names The following diagram shows the SI-T/V7 Unit external appearance and component names.

Switch Setting DIP Switch The following table shows the SI-T/V7 Unit DIP switch settings. 1 2 3 4 OFF Name Baud rate Data length Station address Label Status S1-1 OFF 4 Mbps (MECHATROLINK-I)*1 ON 10 Mbps (MECHATROLINK-II) OFF 17-byte data transmission (MECHATROLINK-I/ MECHATROLINK-II) ON 32-byte data transmission (MECHATROLINK-II)*1 OFF Set the10’s digit of the station number to 2. Invalid if the maximum number of units including the S2 of the rotary switch is 20.
3 Component Names and Settings Station-number Setting A station number is set by both the S1-3 DIP switch and the S2 rotary switch. Station numbers from 21 to 3E are valid. Although 20 or 3F can be set as a station number, do not use these settings because they will be faulty. S1-3: Set the 10’s digit of the station number. OFF = 2 (2X) ON = 3 (3X) S2: Set the 1’s digit of the station number.
4 Installation and Wiring WARNING • 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. IMPORTANT 4.1 Route the MECHATROLINK communications cables separately from the main circuit wiring and other power lines.
