Page 9: Overview
1 Overview Overview The SI-T/V7 Interface Unit is an interface unit that connects to the high-speed 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. -

Page 18: Transmission Interface
Transmission Interface MECHATROLINK-II Cyclic Transmissions As a MECHATROLINK-I/MECHATROLINK-II slave, the SI-T/V7 exchanges control data and I/O data with a control device, such as a controller. Communications with the controller are executed by sending response data timed to the reception of command data for the local station address from the controller in each transmission cycle. -
Page 19: Basic Format Of Data Transfer
5 Transmission Interface Basic Format of Data Transfer The basic format for transferring data is as follows. The size of the header for a data link layer is fixed at two bytes. By setting pin 2 on DIP switch S1, either 17 bytes (17-byte mode) or 32 bytes (32-byte mode) can be selected as the data size for the data link layer. -

7 MECHATROLINK-II Commands MECHATROLINK-II Commands Main Commands The format of the main commands are as follows. No Operation (NOP) Byte Command Response ALARM STATUS RWDT Only the ALARM and STATUS fields of the response data can be monitored. This command can be used in all phases. - Page 24 Read Parameter (PRM_RD) Byte Command Response PRM_RD PRM_RD ALARM STATUS SIZE SIZE PARAMETER RWDT The PRM_RD command is used to read the Inverter's internal constants. For offline parame- ters, it reads the most recently updated setting values. This command can be used in all phases. Note: If the MECHATROLINK-II 32-byte mode is used, PRM_RD can be used only in a sub-command.
- Page 25 7 MECHATROLINK-II Commands Write Parameter (PRM_WR) Byte Command Response PRM_WR PRM_WR ALARM STATUS SIZE SIZE DATA DATA RWDT The PRM_WR command is used to write the Inverter's internal constants. To save the setting value in the Inverter's EEPROM, set the CONFIG_MOD in the CONFIG command to 1.
- Page 26 Read ID (ID_RD) Byte Command Response ID_RD ID_RD ALARM STATUS DEVICE_CODE DEVICE_CODE OFFSET OFFSET SIZE SIZE RWDT The ID_RD command is used to read the ID number. The following table shows the applicable DEVICE_CODE. Because of ID area limitations, no more than eight bytes can be read, so use the OFFSET and SIZE to specify the range.

- Page 29 7 MECHATROLINK-II Commands Clear Alarm or Warning (ALM_CLR) Byte Command Response ALM_CLR ALM_CLR ALARM STATUS ALM_CLR_MOD ALM_CLR_MOD ALM_DATA RWDT The ALM_CLR command is used to clear the alarm and warning status. This command changes the status of the slave station. It does not remove the cause of a fault. After the cause of the alarm or warning has been removed, this command is then used to clear the status of the alarm or warning.
- Page 30 MECHATROLINK-II Connection (CONNECT) Byte Command Response CONNECT CONNECT ALARM STATUS COM_MOD COM_MOD COM_TIM COM_TIM RWDT The CONNECT command is used to set the communications mode and establish a connec- tion. After the connection is established, the phase moves to phase 2. If a transfer fault is detected after moving to phase 2 or phase 3, notification is given of the fault.
- Page 31 7 MECHATROLINK-II Commands • MECHATROLINK-I (VER: 10H) Set the factor of the 2 ms transmission cycle to COM_TIM (communications time). The setting range satisfies the following formulas. 2 [ms] ≤ COM_TIM ≤ 64 [ms] COM_TIM is multiplied by a factor of 2. In the following cases, a warning is generated and the command is ignored.
- Page 32 Disconnection (DISCONNECT) Byte Command Response DISCONNECT DISCONNECT ALARM STATUS RWDT The DISCONNECT command is used to close the connection and move to phase 1. After moving to phase 1, no check for transmission faults is executed. This command can be used in phases 2 and 3. If this command is received while in phase 2 or 3, the data for the control command to the Inverter is cleared to 0, and a fault reset command is carried out for the Inverter.

Page 44: Protective Operations
Protective Operations Fault Detection Processing Faults can be detected by two methods: Inverter fault detection and SI-T/V7 fault detection. The SI-T/V7 is notified of Inverter faults by the internal interface, and the SI-T/V7 sends the response data, ALARM or STATUS. The SI-T/V7 notifies Inverter of SI-T/V7 faults by the internal interface, and the faults are simultaneously sent the response data, ALARM or STATUS. -
