11.1.1 Introduction
Chapter 11 Communication Function
This chapter is to explain SV-iS7 inverter serial communication’s standard, installation, and program with PC or FA
computers. The communication method was designed to drive or monitor SV- iS7 inverter series in long distance
through PC or FA computers.
1) Benefits under the communication method
It is easy to apply inverters into automations in factories, because inverters can be driven or monitored according to
user’s programs.
* possible to monitor or modify parameters through computers
(example: T_acc, T_dec, frequency, and lost command)
* Interface configuration regarding to RS-485 standard:
1) Possible to execute communications between the inverter and computers by numerous companies
2) Capable of controlling up to 16 inverters at a time with single computer due to the multi-drop link
system
3) Interface for noise immunity environment
Inverters can communicate through RS-232/485 converters with computers that are embedded with the RS-232 card.
The standard and performance of converters may vary by manufactures, but share basic functions. More details about
standard and guideline are advised to follow under the manual provided by specific manufactures.
