MG.90.A2.02 – VLT is a registered Danfoss trademark
30
FCM 300 PROFIBUS / VLT 2800 PROFIBUS
Parameters
■
FC motor and VLT 2800 parameters
Only the PROFIBUS specific parameters (800 - 805
and 904 . . ) are described in this manual. All other
parameters and their functions are unaffected by the
PROFIBUS option. We refer to the parameter
description in the design guide on the FC motor
Series (MG.03.Bx.02) and the design guide on the
VLT 2800 Series (MG.28.Ex.02).
Special attention must be given to the following
parameters that are not described in this manual:
-
502 - 508: Selection of how to gate PROFIBUS
control commands with control
commands on the digital inputs of the
FC motor / VLT2800.
-
512:
Control word profile, selects a control
word according to PROFIDRIVE or a
Danfoss specified control word.
-
515 - 543: Data readout parameters that can be
used to read various actual data from
the VLT, as for example actual status
on the analog and digital inputs of the
FC motor / VLT 2800 thus using these
as inputs to the master.

PROFIBUS specific parameters
✭
Factory setting
800 Protocol select (PROTOCOL SELECT)
✭
DP
[1]
Function:
Selection of the PROFIBUS protocol supported by the
master.
Description of selections:
-
DP
: Communication according to DIN 19245 part
3.
Updating parameter 800, even with an
unchanged data value, will initialise the
PROFIBUS option, meaning that all
communication parameters such as slave addresses,
PPO type etc. will be updated.
803 Bus time out (BUS TIME OUT)
Selection:
✭
1 - 99 sec
1 sec
804 Bus time out function (TIME OUT FUNCT.)
Selection:
✭
Off (OFF)
[0]
Freeze output frequency (FREEZE OUTPUT)
[1]
Stop with auto restart (STOP)
[2]
Output frequency = JOG freq. (JOGGING)
[3]
Output freq. = Max. freq. (MAX SPEED)
[4]
Stop with trip (STOP AND TRIP)
[5]
Select Setup 2
[8]
Function:
The time out counter is triggered at the first reception
of a valid control word i.e. bit 10 = ok, when DP is
used.
The
time out
function can be activated in two different
ways:
1. CTW is not updated within the time specified in
parameter 803.
2. Time out is triggered if the CTW is not valid, see
parameter 805.
The FC motor / VLT 2800 remains in time out state
until one of the following conditions is true:
1. Valid control word (Bit 10 = ok) is received. If
Stop
with trip
is selected, reset must also be activated.
If
Select setup 2
is selected, the FC motor / VLT
2800 will remain in Setup 2 until parameter 4 is
changed.
2. Parameter 804 =
Off
⇒
control via PROFIBUS is
resumed and the most recent control word is
used.
Description of selections:
-
Freeze output frequency
: Freeze output frequency
until communication is resumed.
-
Stop with auto restart
: Stop with auto restart
when communication is resumed.
-
Output frequency = JOG freq.
: Motor will run at
JOG frequency until communication is
resumed.
-
Output frequency = Max. freq.
: Motor will run at
max. frequency until communication is resumed.
-
Stop with trip
: Motor is stopped, reset needed for
restart, see explanation above.
-
Select setup 2.
