Bit 06, Ramp stop/start:
Bit 06 = ‘0’ causes a stop, in which the motor speed is
ramped down to stop via the selected
ramp down
parameter. Bit 06 = ‘1’ permits the frequency converter to
start the motor, if the other starting conditions have been
fulfilled.
NOTE
In 8-53 Start Select Start select a selection is made to define
how Bit 06 Ramp stop/start gates with the corresponding
function on a digital input.
Bit 07, Reset:
Bit 07 = ‘0’ no reset. Bit 07 = ‘1’ resets a trip. Reset is
activated on the leading edge of the signal, i.e. when
changing from logic ‘0’ to logic ‘1’.
Bit 08, Jog:
Bit 08 = ‘1’ causes the output frequency to be determined
by
3-19 Jog Speed [RPM] .
Bit 09, Selection of ramp 1/2:
Bit 09 = ‘0’ means that ramp 1 is active (
3-40 Ramp 1 Type
to 3-47 Ramp 1 S-ramp Ratio at Decel. Start ). Bit 09 = ‘1’
means that ramp 2 ( 3-50 Ramp 2 Type to 3-57 Ramp 2 S-
ramp Ratio at Decel. Start ) is active.
Bit 10, Data not valid/Data valid:
This bit tells 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. The control word is always contained in
the telegram, regardless of which type of telegram is used,
so this function is useful for ‘turning off’ the control word
when not required for updating or reading parameters.
Bit 11, Relay 01:
Bit 11 = ‘0’ Relay not activated. Bit 11 = ‘1’ Relay 01
activated, provided
Control word bit 11 has been chosen in
5-40 Function Relay .
Bit 12, Relay 02:
Bit 12 = ‘0’ Relay 02 has not been activated. Bit 12 = ‘1’
Relay 02 has been activated, provided
Control word bit 12
has been chosen in 5-40 Function Relay .
Bit 13/14, Selection of set-up:
Bits 13 and 14 are used to select one of four menu set-ups
according to the following table:
Set-up Bit 14 Bit 13
1 0 0
2 0 1
3 1 0
4 1 1
The function is only possible when Multi-Set-ups is selected
in 0-10 Active Set-up .
NOTE
In 8-55 Set-up Select a selection is made to define how Bit
13/14 gates with the corresponding function on the digital
inputs.
Bit 15 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 Reversing Select . Bit 15 causes reversing only
when Ser. communication , Logic AND or Logic OR is
selected.
