VLT
®
FCM Series
Bit 15 = "0" means that the timers for motor thermal
protection and VLT thermal protection, respectively,
have not exceeded 100%. Bit 15 = "1" means that
one of the timers has exceeded 100%.
Control word under FC Profile (parameter
512 = FC Drive)
The control word is used for sending commands from
a master (e.g. a PC) to a slave (FC motor).

Bit 00:
Bit 00 is used for choosing between the two
pre-programmed references (parameters 215-216)
in accordance with the following table:

NB!:
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. Note: 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:
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 have been
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, Hold / 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.
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. 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, 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.
