Precautions
• When it is necessary to execute comparison and outputting as soon as the current value of a high-speed counter changes,
use the high-speed comparison table, multi-output high-speed comparison table, or one of the DHSCS, DHSCR, and DHSZ
instructions.
• Do not overwrite the current value of a high-speed counter using the DHCMOV instruction while executing the pulse density
(rotation speed measurement) or the DSPD instruction.
The DHCMOV instruction is mainly used to read the current value of the high-speed counter/pulse width
measurement and change the current address (in the user units) or the current address (in the pulse unit) of
positioning.
