Communication Function (Common Serial - Toshiba TOSVERT VF-S9 Instruction Manual

6.17 Communication function (Common serial)

Refer to the COMMUNICATIONS EQUIPMENT USER'S MANUAL for details.
• Function
The VFS9 Series allows a data communication network to be constructed for exchanging data between
a host computer or controller (referred to collectively as the computer) and the inverter by connecting an
optional RS232C or RS485 communication conversion unit.
<Computer-linking functions>
The following functions are enabled by data communication between the computer and inverter
(1) Monitoring inverter status (such as the output frequency, current, and voltage)
6
(2) Sending RUN, STOP and other control commands to the inverter
(3) Reading, editing and writing inverter parameter settings
<RS232C communication>
Data can be exchanged between one computer and one inverter.
<RS485 communication>
Data can be exchanged between the computer and a maximum of 64 inverters.
The following are available as common serial optional units:
• RS232C communications conversion unit (Model: RS2001Z)
Communications cable (Model: CAB0011, 1m long; CAB0013, 3m long; or CAB0015, 5m long)
• RS485 communication conversion unit with terminal board (Model: RS4001Z)
Communication cable (Model: CAB0011, 1m long; CAB0013, 3m long; or CAB0015, 5m long)
Note 1.: Limit the distance between the common serial optional units and the inverter to 5m.
2.: Set Data transfer speed to 9600 bps or less if data exchange between the common serial optional units
: Data transfer speed
: Parity
: Inverter number
: Communication error trip time
and the inverter.
