Inverter parameter access error (SD1150)

Device
number
SD1150 Inverter parameter access error
When an out-of-range setting value is written to a parameter or an out-of-range frequency is set using sequence programs, or
when writing is attempted while writing is disabled, a write error occurs and an error code is stored in SD1150.
<Parameters>
Parameter number + H8000 is stored to SD1150.
Example) If an error occurs when Pr.0 Torque boost is written, H8000 (H0 + H8000) is stored to SD1150.
If an error occurs when Pr.10 DC injection brake operation frequency is written, H800A is stored to SD1150.
<Operation mode, setting frequency, batch clear of fault records, and all parameter clear>
HFFFF is stored to SD1150. (The initial values is "0".)
POINT POINT
• The error code stored after the error occurrence will be cleared by writing "0" in SD1150. (The error code is retained until "0"
is written in SD1150.)
