Page 4: Technical Data
3. Technical data Introduction The RVS-AXO is a starter designed for use with standard three-phase, three-wire, squirrel cage, induction motors. It provides the best method of reducing current during motor starting. The RVS-AXO starts the motor by supplying a slowly increasing voltage, providing soft start and smooth acceleration, while drawing the minimum current necessary to start the motor. -

Page 16: Introduction
1. INTRODUCTION This document summarizes the serial link protocol to / from the DIGITAL SOFT STARTER (RVS-AXO). Features: RS485 Hardware. Asynchronous serial link. Half duplex. Format: Modbus RTU Mode (Remote Terminal Unit Mode). - Binary, - Each character includes 11 bits: - 1 start bit - 8 data bits, least significant bit sent first. -
Page 17: Basic Structure Of The Serial Link Frame
2. BASIC STRUCTURE OF THE SERIAL LINK FRAME Modbus RTU frame have the same principal structure for both the "Query" transmission from the Master to the Slave (RVS-AXO) and the Response transmission from the Slave to the Master. "Sync": Silent time of at least 3.5 character (3.5 * 11 bit times). Byte 1: Serial Link No. -

5. SETTING PARAMETERS (Holding registers) All parameters are word (two bytes) parameters. The protocol supports Reading with function 3 and modifying these parameters with functions 6, 16. Any one of these parameters must modify with care. Harmful results can occur both to the motor and the RVS-AXO by inadequate settings of some parameters. - Page 22 Voltage rise time at Effective only when 0…15 (1…30Sec) start register @20 set to 1 / Modbus control.

7. DIAGNOSTICS Modbus Function 08, as implemented in the RVS-AXO supports only Sub-function $0000. It provides for "loopback" (Return Query Data) feature, for checking the Communication Serial Link between the master and the RVS-AXO. To request RVS-AXO # 18 to return Query data, the master should send following Query frame: Byte 1: Serial Link No. - Page 28 EXCEPTION RESPONSES When the master sends a query frame to an RVS-AXO, one of the following four responses from the RVS-AXO is possible: 1. When no communication error is detected in the query, and no mistake is found by the communication program module in the RVS-AXO, a normal response is returned.
- Page 29 Exception Codes supported by the RVS-AXO: Exception Code Type Comment Illegal Function Requested Function is not supported. Functions 1..6, 8, 15 or 16 are supported. Illegal Data Address Data address is not allowable. Illegal Data Value Data Value is not in allowable range. RVS-AXO Busy RVS-AXO is busy now.
- Page 30 Note: There are cases where the RVS-AXO returns Normal response, but the requested action cannot be performed, or is modified by the RVS-AXO. Few examples are: Requested Action Performed Action Writing Setting parameters during start process Ignored. Writing few parameters (Function 16), some are out of range Limiting allowed range.
