Serial Communication Reference - Danfoss VLT 2800 Series Operating Instructions Manual

Bit 01, Drive ready:
Bit 01 = "1". The 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 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, Trip lock:
Bit 06: "1" means that there is a trip lock.
Bit 07, No warning/warning:
Bit 07 = "0" means there is no warning.
Bit 07 = "1" means a warning has occurred.
NOTE
All warnings are discribed in the Operation
Instructions.
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
MG.10.S1.22 - VLT is a registered Danfoss trademark
VLT® Serie 2800 and VLT® Serie 6000 Modbus RTU
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.
Bit 12, No function:
Bit 12 has no function.
Bit 13, Voltage warning high/low:
Bit 13 = "0" means that there is no voltage warning.
Bit 13 = "1" means that the DC voltage of the VLT 6000
HVAC intermediate circuit is too low or too high.
See the voltage limits on page 160.
Bit 14, Current limit:
Bit 14 = "0" means that the output current is smaller
than the value in parameter 215 Current limit I
Bit 14 = "1" means that the output current is higher
than the value in parameter 215 Current limit I
the frequency converter will trip after the time set in
parameter 412 Trip delay overcurrent, I
Bit 15, Thermal warning:
Bit 15 = "0" means there is no thermal warning.
Bit 15 = "1" means that the temperature limit has been
exceeded either in the motor, in the frequency converter
or from a thermistor connected to an analogue input.
å Serial communication reference
The serial communication reference is transmitted to
the frequency converter in the form of a 16-bit word.
The value is transmitted as whole numbers 0 - ±32767
(±200 %). 16384 (4000 Hex) corresponds to 100 %.
The serial communication reference has the
following format:
0-16384 (4000 Hex) - 0-100 % (par. 204 Minimum
ref. - Par. 205 Maximum ref.).
