Fuji Electric FVR-E11S-7EN User Manual

9-18
(5) Command type character
In a standard frame, set "R" in ASCII for a polling (reading) request, or set "W" in ASCII for a
selecting (writing) request. Set "E" in ASCII for a resetting command. Only the upper case characters
are valid.
In a short frame, the function is directly designated using a command type character. Refer to (3)
Short Frame in section 9-4-11 Function Code List for details.
(6) Function type character and tens digit and units digit of function number
A request function is designated in three characters. Refer to section 9-4-11 Function Code List for
details.
(7) Special additional data
This is normally a space (20H). In a response frame issued by an inverter to request for frequency
monitor (M09), a minus sign is set in ASCII during reverse rotation output.
(8) Data
In a selecting (writing) request frame sent from the host to an inverter, designate writing data. Refer
to section 9-4-10 Data Type. In a polling (reading) frame, set space or arbitrary letter or number
character. in a selecting response frame sent from an inverter to the host, data "0000" or an error
code is contained, and in a polling frame, data or an error code is contained.
(9) End-of-text character (ASCII; ETX)
03H in binary.
(10) Upper digit and lower digit of checksum
A binary sum of all the characters from tens digit of the station address to the end-of-text character is
obtained and the lower two digits of it in hexadecimal notation are expressed in ASCII codes. Set in
the upper case.
Example. When the binary sum is "17EH"→ The upper digit of the checksum is "7" in ASCII. The
lower digit of the checksum is "E" in ASCII.
9-4-8 Broadcasting
An operation command or frequency command destined to station address "99" is received and
processed by all the inverters as broadcasting. However, no response is issued by the inverters.
