Operating instructions

Bit 08, Jog 1 OFF/ON
Activation of the pre-programmed speed in par. 8-90
Bus Jog 1 speed . JOG 1 is only possible if
bit 04 = "0" and bit 00 - 03 = "1".
Bit 09, Jog 2 OFF/ON
Activation of the pre-programmed speed in par. 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
Is used to tell the frequency converter 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 telegram, regardless
of which type of telegram is used, i.e. it is possible to turn off the control word if you do not wish
to use it in connection with updating or reading parameters.
Bit 11, No function/Slow down
Is used to reduce the speed reference value by the amount given in par. 3-12
Catch up/slow
down
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
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 fol-
lowing 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 deter-
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 .
Set-up
Bit 13 Bit 14
1 0 0
2 1 0
3 0 1
4 1 1
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 .
NB!
Bit 15 causes reversing only when
Ser. communication, Logic or or Logic and is
selected.
