Cause
01H
Function Code Error
Attempted to set a function code from a PLC other than 03H, 08H, and 10H.
02H
Register Number Error
A register number specified in the command message does not exist.
Attempted to send a broadcast message using other register numbers than 0001H or 0002H.
03H
Bit Count Error
Read data or write data is greater than 16 bits. Invalid command message quantity.
In
a write message, the “Number of Data Items” contained within the message does not equal twice the amount of data words
(i.e., the total of Data 1+ Data 2, etc.).
21H
Data Setting Error
Control data or parameter write data is outside the allowable setting range.
Attempted to write a contradictory parameter setting.
22H
Write Mode Error
Attempted to write while the drive was operating to a parameter that cannot be written to during run.
During
an EEPROM data error (CPF06), the master attempted to write to a parameter other than A1-00 to -05, E1-03, or o2-04.
Attempted to write to read-only data.
23H
DC Bus Undervoltage Write Error
Attempted to write from the master during an undervoltage fault (Uv1).
Attempted to execute and Enter command during Uv1.
24H
Write Error During Parameter Process
Master attempted writing to the drive while the drive was processing parameter data.
u
Slave Not Responding
In the following situations, the slave drive will ignore the command message sent from the master, and not send a response
message:
When a communications error (overrun, framing, parity or CRC-16) is detected in the command message.
When the slave address in the command message and the slave address in the drive do not match (remember to set the slave
address for the drive using H5-01).
When the gap between two blocks (8 bit) of a message exceeds 24 bits.
When the command message data length is invalid.
Note: If the slave address specified in the command message is 00H, all slaves execute the write function, but do not return response messages
to the master.
