You can use the pulse rate value that is read in the user program to calculate the pulse frequency.
Use the following formula to calculate the input pulse frequency.
The time window is set in milliseconds. The unit of the frequency that is found with the above formula is
in kHz. Convert the value to the required unit.
You can use the pulse rate value that was read in the user program to calculate the rotation rate (r/min).
The rotation rate is the number of motor rotations per minute. Use the following formula to calculate the
rotation rate.
1
Double-click the Incremental Encoder Input Unit in the Multiview Explorer.
The following tab page is displayed.
