Bus Feedback 2
(BUS FEEDBACK 2)
Value:
0 through 16384 decimal (0 through 4000 Hex)
★
0
Function:
Via serial communication, a bus feedback value can be written in this
parameter that will become part of the feedback handling system. Bus
Feedback 2 will be added to any feedback value on terminal 54.
Description of choice:
Write the required bus feedback value via the serial communication.
NOTE
Parameters 555,
Bus Time Interval, and 556, Bus
Time Interval Function, are only active when
FC Protocol has been selected in parameter
500,
Protocol.
555
Bus Time Interval
(BUS TIME INTERVAL)
Value:
1 to 99 sec.
★
60 sec.
Function:
In this parameter, the maximum time allowed between the receipt of two
packets in a row is set. If this time is exceeded, the serial communication
is assumed to have stopped and the choice made in parameter 556,
Bus Time Interval Function, will be carried out.
Description of choice:
Set the required time.

Stop (STOP)
[2]
Jogging (JOG FREQUENCY)
[3]
Max. output frequency (MAX FREQUENCY)
[4]
Stop and trip (STOP AND TRIP)
[5]
Function:
In this parameter, the required reaction from the drive is selected when
the time set in parameter 555, Bus Time Interval, has been exceeded.
Description of choice:
The output frequency of the drive can be frozen at the present value,
frozen as selected in parameter 211, Preset Reference 1, frozen as
selected in parameter 202, Maximum Output Frequency, or stop and
show a fault.
✭
Indicates default parameter. Depending upon the application, the drive may be delivered with other parameters selected.
560
N2 override release time
(N2 OVER.REL.TIME)
Value:
1 - 65534 (OFF) sec.
★
OFF
Function
The maximum time is set between the receipt of two N2 messages. If the
time is exceeded, serial communication is assumed stopped and all
points in the N2 point-map which are overridden will be released in the
following order:
1. Release analog outputs from point address (NPA) 0 to 255.
2. Release binary outputs from point address (NPA) 0 to 255.
3. Release internal floating points from point address (NPA) 0 to 255.
4. Release internal integer points from point address (NPA) 0 to 255.
5. Release internal byte points from point address (NPA) 0 to 255.
Description of choice:
Set the required time.
565
FLN bus time interval (FLN TIME INTER.)
Value:
1 - 65534 sec.
★
60 sec.
Function
The maximum time is set between the receipt of two FLN messages. If
the time is exceeded, serial communication is assumed stopped and
the required reaction is set in parameter 566, FLN Bus Time Interval
Function.
Description of choice:
Set the required time.

[5]
Function
The required reaction from the adjustable frequency drive is selected
when the time set in parameter 565, FLN Bus Time Interval, has been
exceeded.
Description of choice:
The output frequency of the adjustable frequency drive can be frozen
at the present value at any given time, frozen at parameter 211, Preset
Reference 1, frozen at parameter 202, Max. Output Frequency, or
stop output and show a fault.
