Bit 00
Bit 00 is used for choosing between the two pre-
programmed references (parameters 215-216) in
accordance with the following table:
Preset ref. Parameter
1 215
2 216
Table 3.27
NOTICE
Parameter 508 is where to choose the way bits 1/12 are
to be combined (gated) with the corresponding function
on the digital inputs.
Bit 02, DC brake
Bit 02 = "0" leads to DC braking and stop. Braking current
and duration are set in parameters 132 and 133.
Bit 02 = "1" leads to ramp.
Bit 03, Coasting/enable
Coasting. Bit 03 = "0" leads to a stop.
Bit 03 = "1" means that the frequency converter is able to
start, provided the other conditions for starting have been
fulfilled.

NOTICE
In parameter 502 the choice is made as to how bit 03 is
to be combined (gated) with the corresponding function
in the digital inputs.
Bit 04, Quick-stop/ramp
Bit =1
Quick-stop which uses the ramp time in parameter 212. Bit
04 = "0" leads to a quick-stop.
Bit 04 = "1" means that the frequency converter is able to
Ramp
start, provided the other conditions for starting have been

fulfilled.

Bit 05, Hold/ramp enable
Relay 123 / digital
Bit 05 = "0" means that the given output frequency is

maintained even if the reference is changed.
Relay 123
Bit 05 = "1" means that the frequency converter is again

able to regulate, and the given reference is followed.
Reversing
Bit 06, Ramp stop/start
An ordinary ramp stop that uses the ramp time in
parameters 207/208. Bit 06 = "0" leads to a stop.
Bit 06 = "1" means that the frequency converter is able to
start, provided the other conditions for starting have been
fulfilled.
NOTICE
Bit 00
In parameter 505 the choice is made as to how bit 06 is
0
to be combined (gated) with the corresponding function
1
on the digital inputs.
Bit 07, No function/reset
Reset of trip. Bit 07 = "0" means that there is no reset.
Bit 07 = "1" means that a trip is reset. After reset it will
take approx. 1.5 second until the unit is ready. The status
word will indicate the ready state.
Bit 08, Activation of Jog speed in parameter 213
Bit 08 = "0": Jog speed not activated.
Bit 08 = "1" means that the motor is running at Jog speed.
Bit 10, Data not valid/valid
Used for telling the FC motor whether the control word is
to be used or ignored.
Bit 10 = "0" means that the control word is ignored.
Bit 10 = "1" means that the control word is used. This
function is relevant because the control word is always
contained in the telegram, regardless of the type of
telegram used, i.e. it is possible to disconnect the control
word if it is not to be used in connection with updating or
reading of parameters.
