Danfoss VLT 6000 HVAC Series User Manual

Gives the signal status of the 8 inputs (16, 17, 18, 19,
27, 29, 32 and 33). Input 16 corresponds to the bit to
the extreme left.
'0' = no signal, '1' = signal connected.
Terminal 53, analogue input [V], parameter 522:
Gives the voltage value of the signal on terminal 53.
Terminal 54, analogue input [V], parameter 523:
Gives the voltage value of the signal on terminal 54.
Terminal 60, analogue input [mA], parameter 524:
Gives the current value of the signal on terminal 60.
Pulse reference [Hz], parameter 525:
Gives a pulse frequency in Hz connected to one of the
terminals 17 and 29.
External reference, parameter 526:
Gives the sum of external references as a percentage
(sum of analogue/pulse/serial communication) in the
range from Minimum reference, Ref
MIN
to Maximum
reference, Ref
MAX
.
Status word, parameter 527:
Gives the present status word of the frequency con-
verter in Hex.
Heat sink temperatur, parameter 528:
Gives the present heat sink temperature of the fre-
quency converter. The cut-out limit is 90 ± 5 °C, while
cutting back in is effected at 60 ± 5 °C.
Alarm wor Alarm word, parameter 529:
Gives a Hex code for the alarm on the frequency con-
verter.
Control word, parameter 530:
Gives the present control word of the frequency con-
verter in Hex.
Warning word, parameter 531:
Indicates in Hex whether there is a warning on the fre-
quency converter.
Extended status word, parameter 532:
Indicates in Hex code whether there is a warning on
the frequency converter.
Relay status, parameter 537:
Indicates in binary code whether the output relays of
the are triggered or not.
Warning word 2, parameter 538:
When hex code 80000000 is present in warning word
parameter 531 a warning is written in warning word 2,
parameter 538. The warning is in hex code.
535 Bus feedback 1
(BUS FEEDBACK1)
Value:
0 - 16384 decimal (0 - 4000 Hex)
0
Function:
Via the serial communication port, this parameter al-
lows writing of a bus feedback value which will then
form part of the feedback handling (see page 115). Bus
feedback 1 will be added to any feedback value reg-
istered on terminal 53.
Description of choice:
Write the required bus feedback value via serial com-
munication.
536 Bus feedback 2
(BUS FEEDBACK 2)
Value:
0 - 16384 decimal (0 - 4000 Hex)
0
Function:
Via serial communication, a bus feedback value could
be written in this parameter that would subsequently
become part of the feedback handling system. Bus
feedback 2 will be added to any feedback value on
terminal 54.
Description of choice:
Write the required bus feedback value via the serial
communication.
555 Bus time interval
(BUS TIME INTERVAL)
Value:
1 - 65534 sec.
60 sec.
Function:
In this parameter, the time is set which is expected to
pass as a maximum between the receipt of two tele-
grams in a row. If this time is exceeded, the serial
communication is assumed to have stopped and the
required reaction is set in parameter 556 Bus time in-
terval function.
Description of choice:
Set the required time.
