as to how bit 03 is to be combined (gated) with the
corresponding function in the digital inputs.
B
it 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 frequency converter 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.
B
it 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 frequency converter is again able
to regulate, and the given reference is followed.
B
it 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. 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.
B
it 07, No function/reset
Resetoftrip.Bit07="0"meansthatthereisnoreset.
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.
B
it 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".
B
it 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.
B
it 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.
B
it 11, No function / slow down, relay 123,
digital output terminal 9:
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 11 = "1" will also activate
relay 123 (provided parameter 323 = "Control word
bit 11") and set digital out terminal 9 high (provided
parameter 340 = "Control word bit 11").
B
it 12, No function / catchup, relay 123:
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
catchup are activated (Bits 11 and 12 = "1"), slow
down has the higher priority, i.e. the speed reference
is reduced. Bit 12 = "1" will also activate relay 123
(provided parameter 323 = "Control word bit 12").
B
its 13, Choice of Setup:
Bit 13 is used for choosing between the two menu
Setups in accordance with the following table:
Setup Bit 13
10
21
This function is only possible if Multi-Setups have
been selected in parameter 004.
NB!:
Parameter 507 is used for choosing how
Bit 13 is to be combined (gated) with the
corresponding function on the digital inputs.
B
it 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.
NB!:
Unless otherwise mentioned, the control
word bit is combined (gated) with the
corresponding function on the digital
inputs as a logic "or" function.
S
tatus word (according to Fieldbus
Profile standard)
The status word is used for informing the master (e.g.
a PC) of the condition of a slave (FC motor).
