FC 300 Profibus
Bit 12, No function/Catch up
Is used to increase the speed reference value by the amount given in par. 3-12 Catch up/slow down value.
When bit 12 = "0", no modification of the reference value occurs.
When bit 12 = "1", the reference value is increased.
If both - slowing down and accelerating - are activated (bit 11 and 12 = "1"), slowing down has priority, i.e.
the speed reference value will be reduced.
Bits 13/14, Set-up selection
Bits 13 and 14 are used to choose between the four
parameter set-ups according to the following table:
The function is only possible if Multi Set-up has been
chosen in par. 0-10 Active set-up. The selection
in par. 8-55 Set-up select determines how bits 13
and 14 are linked with the corresponding function
of the digital inputs. Changing set-up while running
is only possible if the set-ups have been linked in
par. 0-12 This set-up linked to.
Bit 15, No function/Reverse
Bit 15 = "0" causes no reversing.
Bit 15 = "1" causes reversing.
Note: In the factory setting reversing is set to digital in par. 8-54 Reversing select.
