D
Negative Values Expressed in 2’s Complements
If the frequency reference bias in n061 is –100%, the minimum unit of setting will be
1% and the data will be converted as follows:
100 (%)/1 (%) = 100 = 0064 Hex
→
2’s complement: FF9C Hex
Bit reversed.
1 is added.
Note
Whether the data is positive or negative is determined by the parameter set value.
The MSB of negative-value data is always set to 1. Data with its MSB set to 1 is not, however,
always negative-value data.
For example, the setting range of the n083 parameter (register 0153 Hex: jump frequency 1) is
within a range from 0.00 to 400.00 Hz. If the jump frequency is 400.0 Hz, the data is obtained from
the following formula and its MSB will be 1.
400.0 (Hz)/0.001 (Hz) = 4000 = 9C40 Hex
D
Setting All Unused Bits to 0
•
Bits 11 through 15 of the RUN command (register 0001 Hex) are unused. When writing the data, be
sure to set all of these bits to 0.
These bits when read are set to 0.
D
No Data Settings in Unused Registers
•
Registers described “not used” may be used for internal processing. Do not write any data to such
registers.
