■ Status word as per FC protocol
The status word is used to inform the master (e.g. a
PC) of the condition of the slave (VLT 6000 HVAC).

Bit 00, Control ready:
Bit 00 = "1". The VLT frequency converter is ready for
operation.
Bit 00 = "0". The VLT frequency converter has tripped.
Bit 01, Drive ready:
Bit 01 = "1". The VLT frequency converter is ready for
operation, but terminal 27 is a logic '0' and/or a
coasting command has been received via serial
communication.
Bit 02, Stand by:
Bit 02 = "1". The VLT frequency converter is able to
start the motor when a start command is given.
Bit 03, No trip/trip:
Bit 03 = "0" means that the VLT 6000 HVAC is not in
an error state.
Bit 03 = "1" means that the VLT 6000 HVAC has
tripped and needs a reset signal in order for operation
to be resumed.

Bit 04, Not in use:
Bit 04 is not used in the status word.
Bit 05, Not in use:
Bit 05 is not used in the status word.
Bit 06, Not in use:
Bit 06 is not used in the status word.
Bit 07, No warning/warning:
Bit 07 = "0" means there is no warning.
Bit 07 = "1" means a warning has occurred.
Bit 08, Speed ≠ ref./speed = ref.:
Bit 08 = "0" means that the motor is running, but
that the present speed is different from the preset
speed reference. This may be the case, i.a. when the
speed is ramped up/down at start/stop.
Bit 08 = "1" means that the present motor speed
equals the preset speed reference.
Bit 09, Local operation/serial communication control:
Bit 09 = "0" means that OFF/STOP has been
activated on the control unit, or that the VLT 6000
HVAC is in Hand mode. It is not possible to control
the VLT frequency converter via serial
communication.
Bit 09 = "1" means that it is possible to control the
frequency converter via serial communication.
Bit 10, Out of frequency range:
Bit 10 = "0" if the output frequency has reached the
value in parameter 201 Output frequency low limit or
parameter 202 Output frequency high limit.
Bit 10 = "1" means that the output frequency is
within the limits stated.
Bit 11, Not running/running:
Bit 11 = "0" means that the motor is not running.
Bit 11 = "1" means that the VLT 6000 HVAC has a
start signal, or that the output frequency is greater
than 0 Hz.
