Bit 10, Data not valid/Data valid
Tell the frequency converter whether to use or ignore the
control word.
Bit 10=0: The control word is ignored.
Bit 10=1: The control word is used. This function is relevant
because the telegram always contains the control word,
regardless of the telegram type. If the control word is not
needed when updating or reading parameter, turn it o.
Bit 11, Relay 01
Bit 11=0: Relay not activated.
Bit 11=1: Relay 01 activated if [36] Control word bit 11 is
selected in parameter 5-40 Function Relay.
Bit 12, Relay 02
Bit 12=0: Relay 02 is not activated.
Bit 12=1: Relay 02 is activated if [37] Control word bit 12 is
selected in parameter 5-40 Function Relay.
Bit 13, Selection of set-up
Use bit 13 to select from the 2 menu set-ups according to
Table 5.36.
Set-up Bit 13
1 0
2 1
Table 5.36 Menu Set-ups
The function is only possible when [9] Multi set-ups is
selected in parameter 0-10 Active Set-up.
To dene how bit 13 gates with the corresponding
function on the digital inputs, use parameter 8-55 Set-up
Select.
Bit 15 Reverse
Bit 15=0: No reversing.
Bit 15=1: Reversing. In the default setting, reversing is set
to digital in parameter 8-54 Reversing Select. Bit 15 causes
reversing only when serial communication, [2] Logic OR or
[3] Logic AND is selected.
