Chapter 8 Built-in High-speed Counter Function
(b) Count function of Revolution/Unit time is used to count the number of pulses for a
specified time while auxiliary mode enable signal is On.
(c) With the displayed number of pulses updated for a specified time and the number of
pulses per revolution input, Revolution/Unit time can be counted.
(d) Number of Revolution per 1 second is indicated after number of pulse per 1 revolution is
set and time is set to 1 second (1000ms). In order to indicate by Revolutions per minute
(RPM), the operation is executed in program.
(e) The example that number of pulse per 1 revolution set to ‘1’ and time is set to 1000 ms is
as shown below. (Ch0)
(f) In order to indicate revolution per minute (RPM), the following program is necessary as
shown below. Use MUL function block and save RPM value at revolution per minute (LINT
type) as 64 bit. At this time, first, change revolution per second (DINT type) to LINT type.
