m+1: Set the beginning word of the operating data area (I).
m+2: Designate the axis parameters.
2. Power up again or restart.
The data for the common parameters set in 1 above is enabled.
3. Set the operating data area.
I: Total number of words (Hex) for the data to be written to the PCU.
I+1: The area in the CPU Unit (DM/EM) where the data is set.
I+2: Beginning word address (Hex) of the area in the CPU Unit’s DM or
EM area where the data is set.
l+3: Beginning address (Hex) of PCU data area where data is to be
stored.
4. Set data.
Set data to be written to the PCU in the area (in the DM or EM Area) spec-
ified by words I to I+2.
5. Execute WRITE DATA.
