Control
Bit 10, data invalid/valid
Tells the frequency converter whether to use or ignore the
control word.
Bit 10 = 0 ignores the control word, making it possible to
turn off the control word when updating/reading
parameters.
Bit 10 = 1 uses the control word. This function is relevant
because the control word is always contained in the
telegram, regardless of which type of telegram is used.
Bit 11, no function/slow down
Used to reduce 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
Used to increase 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, and the speed
reference value is reduced.
Bits 13, set-up selection
Bits 13 is used to select between the 2 parameter set-ups
according to Table 4.9.
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 bit 13 is
linked with the corresponding function of the digital
inputs. Changing set-up while the frequency converter is
running is only possible if the set-ups have been linked in
parameter 0-12 This Set-up Linked to.

Bit 14, not used
Bit 15, no function/reverse
Bit 15 = 0 causes no reversing.
Bit 15 = 1 causes reversing.
NOTICE
In the factory setting, reversing is set to [0] Digital in
parameter 8-54 Reversing Select.
NOTICE
Bit 15 causes reversing only when Ser. communication,
Logic or, or Logic and is selected.

4.4.2 Status Word According to PROFIdrive
The status word is used to notify a master (for example a
PC) about the status of a slave.

Table 4.10 Status Word Bits
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 frequency converter is
switched off (tripped).
When bit 00 = 1, the frequency converter control is ready,
but power is not necessarily supplied to the unit (in case
of a 24 V external supply of the control system).
Bit 13
Bit 01, VLT not ready/ready
0
Same significance as bit 00, however, power is supplied to
1
the unit. The frequency converter 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, OFF 3, or coasting) - or the frequency
converter is switched off (trip).
When bit 02 = 1, bit 00, 01, or 02 of the control word is 1,
and the frequency converter has not tripped.
Bit 03, no error/trip
When bit 03 = 0, no error condition exists in the frequency
converter.
When bit 03 = 1, the frequency converter 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, bit 04 = 0.
When bit 01 of the control word is 1, bit 04 = 1.
