Bit 10=0 causes the control word to be ignored.
Bit 10=1 causes the control word to be used. This function
is relevant because the control word is always contained in
the telegram, regardless of which type of telegram is used.
For example, it is possible to turn off the control word if it
is not intended to be used with updating or reading
parameters.
Bit 11, No function/slow down
Reduces the speed reference value by the amount given in
parameter 3-12 Catch up/slow Down Value .
When bit 11=0, no modification of the reference value
occurs. When bit 11=1, the reference value is reduced.
Bit 12, No function/catch up
Increases the speed reference value by the amount given
in
parameter 3-12 Catch up/slow Down Value .
When bit 12=0, no modification of the reference value
occurs.
When bit 12=1, the reference value is increased.
If both slowing down and accelerating are activated (bits
11 and 12=1), slowing down has priority, for example the
speed reference value is reduced.
Bits 13/14, Set-up selection
Selects between the 4 parameter set-ups according to
Table 11.23 .
The function is only possible if [9] Multi Set-up has been
selected in parameter 0-10 Active Set-up . The selection in
parameter 8-55 Set-up Select determines how bits 13 and
14 are linked with the corresponding function of the
digital inputs. Changing set-up while running is only
possible if the set-ups have been linked in
parameter 0-12 This Set-up Linked to .

Bit 15, No function/Reverse
Bit 15=0 causes no reversing.
Bit 15=1 causes reversing.
Note: In the factory setting, reversing is set to
[0] Digital
input in parameter 8-54 Reversing Select .
NOTICE
Bit 15 causes reversing only when the following is
selected:
•
Serial communication.
•
Logic or.

Table 11.24 Bit Values for Status Word, PROFIdrive Profile
Explanation of the status bits
Bit 00, Control not ready/ready
When bit 00=0, bit 00, 01 or 02 of the control word is 0
(OFF 1, OFF 2 or OFF 3) - or the drive is switched off (trip).
When bit 00=1, the drive control is ready, but supply to
the unit is not necessarily present (in the event of 24 V
external supply to the control system).
Bit 01, VLT not ready/ready
Same significance as bit 00, however, there is a supply of
the power unit. The drive is ready when it receives the
necessary start signals.
Bit 02, Coasting/enable
When bit 02=0, bit 00, 01, or 02 of the control word is 0
(OFF 1, OFF 2 or OFF 3 or coasting) - or the drive is
switched off (trip).
When bit 02=1, bit 00, 01, or 02 of the control word is 1;
the drive has not tripped.
Bit 03, No error/trip
When bit 03=0, no error condition of the drive exists.
When bit 03=1, the drive has tripped and requires a reset
signal before it can start.
Bit 04, ON 2/OFF 2
When bit 01 of the control word is 0, then bit 04=0.
When bit 01 of the control word is 1, then bit 04=1.
Bit 05, ON 3/OFF 3
When bit 02 of the control word is 0, then bit 05=0.
When bit 02 of the control word is 1, then bit 05=1.
