FC 300 Design Guide
Is used to increase the speed reference value by the amount given in par. 3-12
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 fol-
lowing table:
The function is only possible if
has been chosen in par. 0-10 Active set-up.
The selection in par. 8-55
mines 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
9.6.6. Status Word according to PROFIdrive Profile (STW)
The Status word is used to notify a master
(e.g. a PC) about the status of a slave.
