8.11

KCS-CFW08

Serial communication module RS-232: is inserted in the place

of the parallel keypad, enabling the RS-232 connection

(connector RJ-6).

The RS-232 serial interface enables the point-to-point

connection (inverter - master). It is gavanically isolated and

enables the use of interconnectingcables in lengthsupto10 m

(32.8 ft)

Through the RS-232 serial interface you can control, set

parameters and monitor the CFW-08. The communication

protocol is based on the communication byenquiry/response

(master/slave),accordingto ISO1745,ISO646, with character

exchange of typeASCII between the inverter (slave) and the

master. The Master can be a PLC, a PC, etc. The maximum

transfer rate is 38400 bps.

For the RS-485 serial communication, both point-to-point (an

inverter and a master) or multipoint (up to 30 inverters and

one master), you can connectthe KCS-CFW08 module to an

KRS-485-CFW08module - for moredetails, refer toitem 8.13.
