Before Installation; Performance Specification; Hardware Specifications - LS RS485/Modbus-RTU User Manual

1. INTRODUCTION
SV-iP5A/iV5 inverter can be controlled and monitored by the sequence program of the PLC or other
master module. The option card provides a terminal block for an RS-485/Modbus-RTU interface. Drives or
other slave devices may be connected in a multi-drop fashion on the RS-485/Modbus-RTU network and
may be monitored or controlled by a single PLC or PC.
1.1. Features
Inverter can be easily applicable to Factory Automation because operation and monitoring is available by
User-program.
* Parameter setting and monitoring is available via computer.
(Ex: Freq. Command, Run/Stop etc.)
* Interface type of RS485 reference:
1) Allows the drive to communicate with any other computers.
2) Allows one computer to control up to 31 drives with multi-drop link system.
3) Noise-resistant interface.
Users can use any kind of RS232/485 converters. The specifications and performances of converters
depend on the manufacturers, but the basic functions are the same. Refer to the converter manual for
detailed specifications and instructions on how to use.
