3.2. Network Baudrate (
f831
)
Set the network baudrate to
f831
. Set the same baudrate in the network. If set AUTO
baudrate, the option unit detects network baudrate automatically.
3.3. Network error detection (
f832
,
f851
,
f852
)
Set the network communication loss action time to
f832
. The network loss detection
starts from the first receiving of the proper frame message. The action of the network
communication loss is set by
f851
.
If
f851
is set other than 4, `
t
' alarm appear at the inverter panel display when
communication loss was detected.
In addition, in the case of
f851
= 5, the inverter output designated frequency in “Preset
speed operation selection(
f852
)”.
3.4. Instance Number (
f833
,
f834
)
Set BACnet® Object Instance number. The instance number should not be duplicate in
the network. The instance number is 22bit data length, and set the number of the option
board as below.
Instance number =
f833
x 1000 +
f834
f834
< 1000
Instance number < 4194304
3.5. MaxMaster (
f835
)
Set the maximum master number of the segment. The BACnet® option unit polls master
station node from 0 to MaxMaster, so set MaxMaster to be small number to be a fast
response time.
3.6. MaxInfoframe (
f836
)
Set the max information frame number to send from this node. Not need to change.
3.7. MAC address monitor(
f853
)
Set the station MAC address to a switch(SW102) on the option board. This station MAC
address should be a unique number on the MS/TP network segment.
f853
is the monitor parameter of MAC address that is set to the address switch on the
option board.
3.8. Number of motor poles for communication(
f856
)
Set the number of motor pole pairs to calculate the motor rotational speed.
This parameter is used only when the motor rotational speed is monitored with a
communication.
