Danfoss FCM305 56 Instruction Manual page 101

Bit 04, Quick-stop/ramp:
Quick-stop which uses the ramp time in parameter
212. Bit 04 = "0" leads to a quick-stop. Bit 04 = "1"
means that the adjustable frequency drive is able to
start, provided the other conditions for starting are
fulfilled.
Note: In parameter 503 the choice is made as to
how bit 04 is to be combined (gated) with the
corresponding function on the digital inputs.
Bit 05, Freeze output frequency/ramp enable:
Bit 05 = "0" means that the given output frequency is
maintained even if the reference is changed. Bit 05 =
"1" means that the adjustable frequency drive is again
able to regulate, and the given reference is followed.
Bit 06, Ramp stop/start:
An ordinary ramp stop that uses the ramp time in
parameters 207/208; in addition, output will be
activated when the output frequency is 0 Hz,
provided OFF 123 has been selected in parameter
340. Bit 06 = "0" leads to a stop. Bit 06 = "1"
means that the adjustable frequency drive is able to
start, provided the other conditions for starting are
fulfilled. Note: In parameter 505 the choice is made
as to how bit 06 is to be combined (gated) with the
corresponding function 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, Jog 1 OFF/ON:
Activation of pre-programmed speed in parameter
509 (Bus JOG 1). JOG 1 is only possible when Bit
04 = "0" and bit 00-03 = "1".
Bit 09, Jog 2 OFF/ON:
Activation of pre-programmed speed in parameter
510 (Bus JOG 2). JOG 2 is only possible when Bit
04 = "0" and Bits 00-03 = "1". If both JOG 1 and
JOG 2 are activated (Bits 08 and 09 = "1"), JOG 1
has the higher priority, which means that the speed
programmed in parameter 509 will be used.
Bit 10, Data not valid/valid:
Used for telling the FCM 300 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
MG.03.B6.2G - VLT is a registered Danfoss trademark
FCM 300 Series
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.
Bit 11, No function/slow down:
Used for reducing the speed reference by the value
in parameter 219. Bit 11 = "0" means that there is
no change of the reference. Bit 11 = "1" means
that the reference is reduced.
Bit 12, No function/catch-up:
Used for increasing the speed reference by the
value of parameter 219. Bit 12 = "0" means that
there is no change of the reference; Bit 12 = "1"
means that the reference is increased. If both slow
down and catch-up are activated (Bits 11 and 12 =
"1"), slow down has the higher priority, i.e. the
speed reference is reduced.
Bits 13, Choice of Setup:
Bit 13 is used for choosing between the two menu
Setups in accordance with the following table:
Setup
1
2
This function is only possible if Multi-Setups have
been selected in parameter 004.
NOTE!
Parameter 507 is used for choosing how Bit 13 is to
be combined (gated) with the corresponding
function on the digital inputs.
Bit 15, No function/reversing:
Reversing of the direction of rotation of the motor.
Bit 15 = "0" leads to no reversing, Bit 15 = "1" leads
to reversing.
NOTE!
Unless otherwise mentioned, the control word bit is
combined (gated) with the corresponding function
on the digital inputs as a logic "or" function.
