Bit 09, Jog 2 OFF/ON
Activates the pre-programmed speed in 8-91 Bus Jog 2
Speed. JOG 2 is only possible if bit 04="0" and bit
00-03="1".
Bit 10, Data invalid/valid
Tells the adjustable frequency drive whether the control
word is to be used or ignored.
Bit 10=“0” causes the control word to be ignored, Bit
10=“1” causes the control word to be used. This function is
relevant, because the control word is always contained in
the message, regardless of which type of message is used,
i.e. it is possible to turn off the control word if it is not
intended to use it in connection with updating or reading
parameters.
Bit 11, No function/Slow-down
Reduces the speed reference value by the amount given in
3-12 Catch up/slow-down value value.
When bit 11="0", no modification of the reference value
occurs. When bit 11="1", the reference value is reduced.
Bit 12, No function/Catch up
Increases the speed reference value by the amount given
in 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
Selects between the four parameter set-ups according to
Table 10.22:
The function is only possible if Multi Set-up has been
selected in 0-10 Active Set-up. The selection in 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 0-12 This Set-up Linked to.
Set-up Bit 13 Bit 14
1 0 0
2 1 0
3 0 1
4 1 1
Table 10.22 Bits 13/14 Set-up Options
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
8-54 Reverse Select.
NOTICE!
Bit 15 causes reversing only when Ser. communication,
Logic or or Logic and is selected.
10.13.5 Status Word According to
