9 HIGH-SPEED COUNTER INSTRUCTION
9.1 High-speed Processing Instruction
641
9
Function number 10
The measuring start and stop of the pulse density (rotation speed measurement) can be controlled for each channel of the
high-speed counter.
Function number 30
For the multi-output high-speed comparison table, specification of a channel is not required. To start the multi-output high-
speed comparison table, set 01H in (s2). To stop it, set 01H in (s3).
Function numbers 40 and 50
The measuring start and stop of pulse width measurement and PWM can be controlled for each channel.
• When values that turn on the same channel are set for start and stop, the stop operation is prioritized.
• To start the multi-output high-speed comparison table (function number: 30), the high-speed counter must be started using
the HIOEN instruction in advance.
• The high-speed input/output instructions operate according to the following parameters.
