FCM 300 / FCD 300 / VLT
®
2800 / DP V1 PROFIBUS
Parameters
Each PCD is defined as a word. If data should be
read from a parameter that has an attribute of Integer
32 or Unsign ed 32 the parameter should be defined
twice in the following PCD’s: PCD 3 and 4, PCD 5
and6,PCD7and8orPCD9and10.
NB!:
The odd subindex must be written first.
Otherwise the data will be interpreted
as 2 low words.1
Example PPO type 6:
PCD 1 CTW/STW
PCD 2 MRV/MAV
PCD 3 Par 515
PCD 4 Par 518
PCD 5 Par 520 High word
PCD 6 Par 520 Low word
PCD 7 Par 538 High word
PCD 8 Par 538 Low word
CTW/STW = Control word / Status word = 16 bit
MRV/MAV = Main Reference Value / Main Actual Value = 16 bit
Par 515 Data readout: Reference % = Datatype 3=>Integer 16
Par 518 data readout: Frequency = Datatype 3 => Integer 16
Par 520 Data readout= Motor current =Datatype 7 =>Unsigned
32
Par 538 Data readout: Alarm Word = Datatype 7 => Unsigned
32
917 Active spontaneous messages
(SPONT. MES)
Value:
✭Off (OFF)
[0]
On (ON)
[1]
Function:
The sponta neous messages function can be
switched on if it is desired to make the FCM
300/FCD 300/VLT 28 00 issue a message when
a war ning or an alarm comes up.
NB!:
Unread spontaneous messages will be stored
in a 16 elements FIFO buffer.
Description of choice:
- OFF: The FCM 300/FCD 300/VLT 2800 will not
issue spontaneous messages or event notification
in c ase of a war ning or a n alarm.
- ON: The FCM 300/FCD 300/VLT 2800 will
issue a spontaneous message when warnings
or a larms are coming up.
918 Station address
(STATION ADDR)
Value:
0-125
✭126
Function:
All stations connected to the same bus must
have a unique address. The station address
can be set in parameter 918.
NB!:
A change in parameter 918 is executed
at next power up or if parameter 800 is
updated. Please see section Station address
in this manual for further information.
927 PCV Operating authority
(PARAMETER EDIT)
Value:
Disable (DISABLE)
[0]
✭Enable (ENABLE)
[1]
Function:
The parameter channel PCV can be blocked meaning
that the modification of parameters through this
channel is not possible. Access through standard
RS 485 interface i s still possible.
Description of choice:
If Disable [0] is selected, parameter processing through
Profibus is not active. If Enable [1] is selected,
parameter processing through Profibus is active.
928 Control authority
(PROCESS CONTROL)
Value:
Disable (DISABLE)
[0]
✭Enable (ENABLE)
[1]
Function:
The process control (a djustment of control word, speed
reference value and of t he following varia ble PCD) can
be blocked. Control through the control card terminals
