Programming
means that the speed programmed in parameter 509 will
be used.
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.
Bit 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").
Bit 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").
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
Table 3.24
This function is only possible if Multi-Setups have been
selected in parameter 004.
NOTICE
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.

NOTICE
Unless otherwise mentioned, the control word bit is
combined (gated) with the corresponding function on
the digital inputs as a logic "or" function.
Status 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).

Bit 00 = "0" means that bit 00, 01 or 02 of the control
word is "0" (OFF1, OFF2 or OFF3), or that the frequency
converter has tripped.
Bit 00 = "1" means that the frequency converter control is
ready.
