Counter stop via terminal 33
The start signal (terminal 18) must be active, i.e. logical

, until the output frequency is equal to the reference.
The start signal (terminal 18 = logical

) must then be
removed before the counter value in parameter 344
has managed to stop the VLT frequency converter.
