Serial Communication - Danfoss VLT 6000 HVAC Series Design Manual

Serial communication 500 - 556

In this parameter group, the serial communication of
the frequency converter is set up.
There is a choice of three protocols: FC protocol,
Metasys N2 and Landis/Staefa. In order to use serial
communication, address and baudrate must always
be set. In addition, such present operational data as
reference, feedback and motor temperature can be
read via serial communication.
500 Protocol
(PROTOCOL)
Value:
FC protocol (FC PROTOCOL)
Metasys N2 (METASYS N2)
Landis/Staefa Apogee FLN (LS FLN)
Modbus RTU (MODBUS RTU)
Function:
There is a choice of four different protocols.
Description of choice:
Select the required control word protocol.
501 Address
(ADDRESS)
Value:
Parameter 500 Protocol = FC protocol [0]
0 - 126
Parameter 500 Protocol = Metasys N2 [1]
1 - 255
Parameter 500 Protocol = LS FLN [2]
0 - 98
Parameter 500 Protocol = MODBUS RTU [3]
1 - 247
Function:
In this parameter it is possible to allocate an address
in a serial communication network to each frequency
converter.
Description of choice:
The individual frequency converter must be given a
unique address.
If the number of units connected (frequency converters
+ master) exceeds 31, an amplifier (repeater) must be
used. Parameter 501 Address cannot be chosen via
serial communication, but must be set via the LCP
control unit.

502 Baudrate
(BAUDRATE)
Value:
300 Baud (300 BAUD)
600 Baud (600 BAUD)
1200 Baud (1200 BAUD)
2400 Baud (2400 BAUD)
4800 Baud (4800 BAUD)
9600 Baud (9600 BAUD)
Function:
In this parameter, the speed is programmed at which
data is transmitted via serial communication.
[0]
Baudrate is defined as the number of bits transmitted
[1]
per second.
[2]
[3]
Description of choice:
The transmission speed of the frequency converter
must be set at a value that corresponds to the trans-
mission speed of the master. Parameter 502 Baudra-
teThe data transmission time itself, which is determined
by the baudrate selected, is only part of the total com-
munication time. cannot be selected via serial commu-
nication; it must be set via the LCP control unit.
Possible selections are:
300 - 9600 baud for FC protocol
9600 baud only for Metasys N2
4800 - 9600 baud for Apogee FLN

503 Coasting stop
(COASTING)
1
Value:
1
Digital input (DIGITAL INPUT)
Serial communication (SERIAL PORT)
1
Logic and (LOGIC AND)
Logic or (LOGIC OR)
Function:
In parameters 503-508, a choice can be made to con-
trol the frequency converter via the digital inputs and/
or via serial communication.
If Serial communication [1] is selected, the command
in question can only be activated if a command is given
via serial communication.
If Logic and [2] is selected, the function must in addition
be activated via a digital input.
