VLT® 5000 Crane
Appendix
Control word in FC profile (parameter 512 = FC profile)
The control word is used for sending commands from
a master (eg. a PC) to a slave (VLT 5000 Crane).

Bit 03, Coasting/enable:
Coasting stop. 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 are fulfilled.
Bit 04, Quick stop/ramp up:
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.
Bit 06, Ramp stop/start:
An ordinary ramp stop that uses the ramp time in
parameter 207/208; in addition, output relay 01 or 04
will be activated when the output frequency is 0 Hz,
provided
Relay 123
has been selected in parameter
323 or 326. Bit 06 = "0" leads to a stop. Bit 06 =
"1" means that the frequency converter is able to
start, provided the other starting conditions 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 there is no reset.
Bit = "1" means that a trip is reset.
Bit 08, Activation of Jog speed in parameter 213:
Bit 08 = "0" means that Jog speed is not activated. Bit
08 = "1" means that the motor is running at Jog speed.
Bit 10, Data not valid/valid:
Used for telling the frequency converter 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, ie. 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, Relay 01:
Bit 11 = "0": Relay 01 not activated. Bit 11 =
"1": Relay 01 activated, provided
Control word bit
has been chosen in parameter 323.
Bit 12, Relay 04:
Bit 12 = "0": Relay 04 has not been activated. Bit 12
= "1": Relay 04 has been activated, provided
Control
word bit
has been selected in parameter 326.
Bit 15, No function/reversing:
Reversing to the direction of rotation of the
motor. Bit 15 = "0" leads to no reversing. Bit
15 = "1" leads to reversing.
Please note that in the factory setting, reversing has
been chosen as digital in parameter 506, which
means that Bit 15 will only lead to reversing if
bus,
logic or
or
logic and
(however,
logic and only
together
with terminal 19) has been selected.
NB!:
Unless otherwise mentioned, the control
word bit is combined (gated) with the
corresponding function on the digital
inputs as a logic "or" function.
