Processing of inverter communication error

· The following error processing will be carried out when an error is detected in the message received from the
computer. According to error content, it can be divided into error response not sent and error response sent.
1） Error response not sent
· Serial communication error
In case of parity error and other errors in serial communication
· Error of received data frame length
When received data length is longer than maximum data length of 256-byte or shorter than the minimum
data length (address 1-byte + command code 1-byte + CRC 2-byte) of 4-byte
· CRC Error
Error during receiving CRC checksum of data frame
· Broadcast mode
In broadcast mode, no response is returned.
2） Error response sent
· Command code not defined
When a command code is except 03H, 06H or 10H, error detection will be carried out and an error code
will be returned.
· PDU Error
When number of data for communication message has an error, an error code will be returned.
· Address error
When starting address or starting address + number of registers is beyond the following range of valid
address, an error code will be returned.
(at F4103=0: the time of register number A)
(at F4103=1: the time of register number B)
· Error of specified execution
When setting the register with a value beyond the setting values listed in the data sheet (for frequency
setting of register number [1000 at F4103=0: the time of register number A, 9500 at F4103=1: the time of
register number B], the range of 0-60000 is valid), or no control is permitted when setting the start
command for register number [1001 at F4103=0: the time of register number A, 9501 at F4103=1: the
time of register number B], an error code will be returned.
