In some cases it is required to set a maximum update rate for a driver.
This can be because the data is split to Qinsy and has an update rate of 200Hz even though Qinsy does not require this. At the moment you need to set a maximum update rate in seconds.
So if you would like to set a maximum of 25Hz you will need to enter 0.04 sec.
Change this so the user can enter this value in Hz.
