Bit 06, Ramp stop/start:
Bit 06 = ‘0’ causes a stop, in which the motor speed is deceled to stop via the
selected
decel
parameter. Bit 06 = ‘1’ permits the frequency converter to start
the motor, if the other starting conditions have been fulfilled.
NB!
In par. O-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 par. C-21
Jog
Speed [RPM]
.
Bit 09, Selection of ramp 1/2:
Bit 09 = ‘0’ means that ramp 1 is active (par. H-07
Accel/Decel Time 1 Type
to
par. SP-73
Decel Time 1 S-ramp Ratio at Decel. Start
). Bit 09 = ‘1’ means that
ramp 2 (par. SP-76
Accel/Decel Time 2 Type
to par. SP-81
Decel Time 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 par. E-24
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 par. E-24
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

The function is only possible when
Multi-Set-ups
is selected in par. K-10
Active
Set-up
.
NB!
In par. O-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 par. O-54
Reversing Select
. Bit 15
causes reversing only when
Ser. communication

Logic AND
or
Logic OR
