Internal error code registers
A Modbus query can fail in many ways in the drive. The Modbus
standard does not specify detailed error descriptions. In addition to
the standard error codes, the FSCA-01 module provides an
internal error register area for more detailed diagnostics.
The internal error register area is used if Modbus error code 0x04
occurs. The registers contain information about the last query. You
can figure out the reason of the failure by reading the registers.
The internal error register is cleared when a query has finished
successfully.
