Revolution Signal Pulses per Revolution (Pulse N)
Set the number of pulses per revolution to a value from 1 to 9999.
The following equation is used to compute the rotating speed.
X
N
Rotating speed =
S
−NULL
S: The scaling factor*
X: The number of input pulses from the revolution sensor per minute
N: The number of pulses per revolution
NULL: The null value
* When the scaling factor is 1, the rotating speed is the number of revolutions per minute (min
–1
or rpm). If
the revolution signal is a changed signal, you can set the scaling factor to determine the rotating speed
before the change.
The setting specifying the number of revolution signal pulses per revolution applies to input signals whose
type has been set to pulse. For input signals whose type has been set to analog, there is no need to configure
this setting.
