Страница: 37 / 63

VLT® 5000/ 5000 FLUX/ 6000 HVAC/
8000 AQUA PROFIBUS
- Stop with auto restart: Stop with automatic restart
on resumption of communication.
- Output frequency = Fixed speed frequency:
Motor runs with fixed speed frequency until
resumption of communication.
- Output frequency = max. frequency: Motor runs
with the maximum frequency until resumption
of communication.
- Stop with trip: Motor has stopped, a reset is
necessary for a restart, see explanation above.
- Control without PROFIBUS: Control via PROFIBUS
is inactive; control is possible via the terminals
and/or the RS 485 standard interface until
communication resumes.
- Selection parameter setup 4: Parameter setup
4 is selected in parameter 004; the settings of
parameter setup 4 are used.
Parameter 004 is not reset to the original value
upon resumption of communication.
- Selection parameter setup 2: Parameter setup
2 is selected in parameter 004; the settings of
parameter setup 2 are used.
Parameter 004 is not reset to the original value
upon resumption of communication.
805 Function Control word bit 10
(BIT 10 FUNCT.)
Value:
Without function
(NO FUNCTION) [0]
✭
Bit 10 = 1
⇒
CTW active
(BIT 10 = 1
⇒
CTW ACTIVE) [1]
Bit 10 = 0
⇒
CTW active
(BIT 10 = 0
⇒
CTW ACTIVE) [2]
Bit 10 = 0
⇒
Timeout
(BIT 10 = 0
⇒
TIMEOUT) [3]
Function:
According to the PROFIDRIVE profile, the Control word
and speed reference value are ignored when bit 10 of
the Control word is 0. However, a modification of the
function of bit 10 is possible through parameter 805.
This is sometimes necessary since some masters
set all bits to 0 in different error situations. In these
cases it makes sense to change the function of bit
10 so that the command to stop (coasting) goes to
the frequency converter if all bits are 0.
Description of choice:
- Bit 10 = 1
⇒
CTW active: If bit 10 = 0, the Control
word and speed reference value are ignored.
- Bit 10 = 0
⇒
CTW active: If bit 10 = 1, the Control
word and speed reference value are ignored. If
all bits of the Control word are 0, the frequency
converter will switch to coasting in response here to.
- Bit 10 = 0
⇒
Timeout: If bit 10 = 0, the timeout
function selected in parameter 804 is activated.
- Without function: Bit 10 is ignored, i.e. the Control
word and speed reference value are always valid.
NB!:
During an update of parameter 800 or
during the next turn-on procedure, the
parameter 805 changes too.
808 Profidrive Status word
(PROFIDRV STATUSW)
Value:
✭
Off 2/3 Non inverted (OFF2/3 NON-INVERTED)
[0]
Off 2/3 Inverted (OFF2/3 INVERTED) [ 1]
Function:
This function makes it possible to invert Off 2
and Off 3 bits in the Profidrive Status Word, if
Fieldbus profile is selected in p. 512.
Description of choice:
Off 2/3 Non inverted: Off 2/3 bits are inverted
contrary to Profidrive profile.
Off 2/3 Inverted: Status word is according
to Profidrive profile.
849 Extend Diagnosis
(EXTEND DIAGNOSIS)
Value:
✭
Disable (DISABLE) [0]
Alarm (ALARM) [1]
Alarm and Warning (ALARM AND WARNING) [2]
Function:
This function allows to expand the diagnosis data
to 24 Byte, if this parameter is set to Alarm [1]
and Alarms and Warnings [2].
Description of choice:
Please refer to the section Extended diagnosis
in this manual.
904 PPO type select for DP
(PPO TYPE SELECT)
Value:
✭
PPO type 1 (PPO TYPE 1) [900 ]
PPO type 2 (PPO TYPE 2)
[901 ]
PPO type 3 (PPO TYPE 3) [902 ]
