VLT® FC 100 LonWorks
Bit 06, Ramp stop/start:
Bit 06 set to [0] causes a stop, in which the motor speed is ramped down
to stop via the selected ramp down parameter.
Bit 06 set to [1] permits the frequency converter to start the motor, if
other starting conditions have been fulfilled.
NB!
Start Select
In par.8-53
how Bit 06 Ramp stop/start gates with the correspond-
ing function on a digital input.
Bit 07, Reset:
Bit 07 set to [0] means no reset.
Bit 07 set to [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 set to [1] causes the output frequency to be determined by
par. 3-19 Jog Speed [RPM] .
Bit 09, Selection of ramp:
Bit 09 set to [0] means that ramp 1 is active (par. 3-40 to 3-47).
Bit 09 set to [1] means that ramp 2 (par. 3-50 to 3-57) 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 set to [0] causes the control word to be ignored.
Bit 10 set to [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 for reading parameters.
Bit 11, Relay 01:
Bit 11 set to [0] means that Relay is not activated.
Bit 11 set to [1] activates Relay 01, provided
been chosen in par. 5-40 Function Relay

6 How to control the Frequency Converter
Bit 12, Relay 04:
Bit 12 set to [0] means that Relay 04 has not been activated.
Bit 12 set to [1] activates Relay 04, provided
been chosen in par. 5-40 Function Relay
Bit 13 and 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
1 0
2 0
3 1
4 1
The function is only possible when Multi-Set-up [9] is selected in
Active Set-up

how Bit 13/14 gates with the corresponding function
on the digital inputs.
Bit 15, Reverse:
Bit 15 set to [0] causes no reversing.
Bit 15 set to [1] causes reversing.
