Bit 00, Control not ready/ready
In the case of 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 has switched off (trip).
In the case of bit 00 = “1”, the frequency converter
control is ready, but there is not necessarily a
supply to the power unit present (in the case of
external 24 V supply of the control system).
Bit 01, VLT not ready/ready
Same significance as bit 00, however, there is a
supply of the power unit. The frequency converter
is ready when it receives the necessary start
signals.
Bit 02, Coasting/Enable
In the case of 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 frequency converter has
switched off (trip).
In the case of bit 02 = “1”, bit 00, 01 or 02 of the
control word is “1”; the frequency converter has not
tripped.

Bit 03, No error/Trip
In the case of bit 03 = “0”, no error condition of the
frequency converter exists.
In the case of bit 03 = “1”, the frequency converter
has tripped and requires a reset signal before it
can start.
Bit 04, ON 2/OFF 2
In the case of bit 04 = “0”, bit 01 of the control
word is “1”
In the case of bit 04 = “1”, bit 01 of the control
word is “0”
Bit 05 , ON 3/OFF 3
In the case of bit 05 = “0”, bit 02 of the control
word is “1”
In the case of bit 05 = “1”, bit 02 of the control
word is “0”
Bit 06, Start possible/Start not possible
Bit 06 is always ”0” if FC Drive has been selected
in parameter 512. If Profidrive has been selected in
parameter 512, bit 06 will be ”1” after a switch-off
acknowledgement, after activation of OFF2 or
OFF3, and after switching on the mains voltage.
Start not possible will be reset, with bit 00 of the
control word being set to ”0” and bit 01, 02 and 10
being set to ”1”.
Bit 07, No warning/Warning
In the case of bit 07 = “0”, no unusual situation
exists. In the case of bit 07 = “1”, an unusual status
of the frequency converter has occurred. All war-
nings are described in the operations manual.
Bit 08, Speed
≠
reference / Speed = reference
In the case of bit 08 = “0”, the current speed of the
motor deviates from the set speed reference value.
This may occur, for example, when the speed is
being changed during start/stop through ramp up/
down.
In the case of bit 08 = “1”, the current speed of the
motor corresponds to the set speed reference
value.
Bit 09, Local operation/Bus control
Bit 09 = “0” indicates that the frequency converter
has been stopped by means of the stop switch of
the control panel, or that Local has been selected
in parameter 002.
In the case of bit 09 = “1”, the frequency converter
can be controlled through the serial interface.
