4. How to Control the Frequency Converter
Bit 09, Selection of ramp 1/2:
Bit 09 = "0" means that ramp 1 is active (parameters 3-40 to 3-47).
Bit 09 = "1" means that ramp 2 (parameters 3-50 to 3-57) is active.
Bit 10, Data not valid/Data valid:
Is used to tell the frequency converter wheth-
er the control word is to be used or ignored.
Bit 10 = '0' causes the control word to be ig-
nored, Bit 10 = '1' causes the control word to
be used. This function is relevant, because the

word if you do not wish to use it in connection
with updating or reading parameters.
