2800 / DP V1 PROFIBUS
Parameters
825 Delayed speed change delay
(SPEED CNG. DELAY)
Value:
20 - 10000 (20 ms-10 s)
✭ 500
Function:
The delay will under certain conditions (see
parameter 826) perform a fixed d e lay before a
speed change will be ac tivated.
Description of choice:
Select the wanted d ela y time.
The status of the timer can be read:
Timer expired: Parameter 528 Bit 7
Timer active: Parameter 528 Bit 8
826 Application control word
(APPL.CTRL.WORD)
Value:
Bus
Bit Bit = 0 Bit = 1
0Nofunction
1 No function Delayed speed change
Function:
The function will perform a precise timing of a
speed change. The speed change can also
be to set speed = 0.
Description of choice:
SettingtheACWbit1to1willfreezeany
following change of the set speed until following
conditions are fulfilled:
- Delayed speed change input (sensor)
changed from 1 to 0
- Delayed speed change dela y time is expired
Delayed speed change input:
FCM300 terminal 5, parameter 335 set to (Delayed
speed change) (23) FCD300/VLT 2800 terminal 33,
parameter 307 set to (Delayed speed change) (26)

delayed speed change can be initiated .
833 Fieldbus enabled
(FIELDBUS ENABLED)
Value:
Disable (DISABLE)
[0]
✭Enable (ENABLE)
[1]
Function:
This function allows to disa ble the commu-
nication interface.
Description of choice:
If Disable [0] is selected no communication warning will
appear, since the communica tion interface is disabled.
Select Enable [1] to ac tivate the communication.
NB!:
Please note that a change in this parameter
will not be exec u ted until the next power
up has been carried through.
849 Extend Diagnosis
(EXTEND DIAGNOSIS)
Value:
✭Disable (DISABLE)
[0]
Alarms (ALARMS)
[1]
Alarm and War nings (ALARM AND WARNINGS)
[2]
Function:
This function allows to expand the diagnosis da ta
to 24 Byte, if this parameter is set to Alarm [1]
and Alarm and Warning [2].
Description of choice:
Please refer to the section Extend diagnosis
in this manual.
