iii) Parameter write and read
Parameter write and read require the setting of the extension codes given in
Appendix 1 Parameter List (Numerical Order). After setting the extension
code, set the instruction code given in Appendix 1 Parameter List
(Numerical Order) and perform write or read.
This function is performed as set in Pr. 77.

Once written, the setting of the HFF instruction code is held, but is
MEMO
cleared to "0" when the drive unit is reset or all clear is performed.
When converting a value having a decimal place, e.g. parameter setting range,
into a data code, make conversion in the setting range whose decimal place has
been carried. Use "HFFFF" with the value "9999" which means no function.
