5000 INTERBUS
MG.10.O1.02 VLT is a registered Danfoss trademark
25
5000 Series has tripped and needs a reset signal in
order to run.
Bit 04, Reserved.
Bit 05, Reserved.
Bit 06, Reserved.
Bit 07, No warning/warning:
Bit 07 = "0" means that there is no unusual
situation. Bit 07 = "1" means that an abnormal
condition has arisen for the VLT 5000 Series. All
warnings are described in the Operating
Instructions.
Bit 08, Speed
≠
ref/speed = ref.:
Bit 08 = "0" means that the actual motor speed is
different from the speed reference set. This can be
the case i.g. while the speed is ramped up/down
during start/stop. Bit 08 = "1" means that the
present motor speed equals the speed reference
set.
Bit 09, Local control/Bus control:
Bit 09 = "0" means that VLT 5000 Series has been
stopped by means of the stop key on the control
panel, or that
Local operation
has been selected in
parameter 002. Bit 09 = "1" means that it is
possible to control the frequency converter via the
serial port.
Bit 10, Out of operating range/Frequency limit OK:
Bit 10 = "0" means that the output frequency is out
of the range set in parameter 225 (Warning: Low
frequency) and parameter 226 (Warning: High
frequency). Bit 10 = "1" means that the output
frequency lies within the mentioned range.
Bit 11, Does not run/running:
Bit 11 = "0" means that the motor is not running.
Bit 11 = "1" means that VLT 5000 Series has a start
signal or that the output frequency is greater than 0
Hz.
Bit 12, VLT OK/stalling, autostart:
Bit 12 = "0" means that there is no temporary over-
temperature on the inverter. Bit 12 = "1" means
that the inverter has stopped because of over-
temperature, but that the unit has not tripped and
will continue, once the overtemperature stops.
Bit 13, Voltage OK/above limit:
Bit 13 = "0" means that the voltage limits of VLT
5000 Series have not been exceeded. Bit 13 = "1"
means that the DC voltage of the VLT 5000 Series
intermediate circuit is too low or too high.
Bit 14, Torque OK/above limit:
Bit 14 = "0" means that the motor current is lower
than the torque limit selected in parameter 221. Bit
14 = "1" means that the torque limit in parameter
221 has been exceeded.
Bit 15, Timers OK/above limit:
Bit 15 = "0" means that the timers for motor
thermal protection (described on page 67) and VLT
thermal protection, respectively, have not exceeded
100%. Bit 15 = "1" means that one of the timers
has exceeded 100%.
Bus reference value (FC Profile):

15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 Bit no.
The frequency reference value is transmitted to the
frequency converter in the form of a 16-bit word.
The value is transmitted as a whole number (0-
32767). 16384 (4000 Hex) corresponds to 100%.
(Negative figures are formed by means of 2's
complement.)
The bus reference has the following format:
