3.6.10 Counter Stop via Terminal 33
The start signal (terminal 18) must be active, i.e. logical '1', until the out-
put frequency is equal to the reference. The start signal (terminal 18 =
logical '0') must then be removed before the counter value in parameter
344 has managed to stop the VLT frequency converter.
