2. When a parameter has an error, Received parameter error (SB004D) turns on and the error code is
stored in Parameter setting status (SW004C).
3. When the parameter is set in the master/local module, contents of the parameter are stored in the
following link special relays (SBs) and link special registers (SWs).
