P511
USS baud rate
(USS baud rate)
S
0 ... 3
{ 3 }
Setting of the transfer rate (transfer speed) via the RS485 interface. All bus participants must
have the same baud rate setting.
0 = 4800 Baud
1 = 9600 Baud
2 = 19200 Baud
3 = 38400 Baud
P512
USS Address
(USS Address)
0 ... 30
{ 0 }
Setting of the FI Bus address.
P513
Telegram downtime
(Telegram downtime)
S
-0.1 / 0.0 /
0.1 ... 100.0 s
{ 0.0 }
If the frequency inverter is directly controlled via the CAN protocol or via RS485, this
communication path can be monitored via parameter (P513). Following receipt of a valid
telegram, the next one must arrive within the set period. Otherwise the FI reports an fault and
switches off with the error message E010 >Bus Time Out<.
The inverter monitors the system bus communication via parameter (P120). Therefore
parameter (P513) must usually be left in the factory setting {0.0}. Parameter (P513) must only
be set to {-,0,1} if faults detected by the optional module (e.g. communication errors on the field
bus level) are not to result in the drive unit being switched off.
0.0 = Off: Monitoring is switched off.
-0.1 = No error: Even if the bus module detects an error, this does not cause the
frequency inverter to be switched off.
0.1… = On: Monitoring is activated.
P514
CAN baud rate
(CAN baud rate (system bus))
S
0 ... 7
{ 5 }
Setting of the transfer rate (transfer speed) via the system bus interface. All bus participants
must have the same baud rate setting.
Note:
Optional modules (SK xU4-
…) only operate with a transfer rate of 250kBaud. Therefore the
frequency inverter must remain at the factory setting (250kBaud).
0 = 10kBaud
1 = 20kBaud
2 = 50kBaud
3 = 100kBaud
4 = 125kBaud
5 = 250kBaud
6 = 500kBaud
7 = 1Mbaud *
*) Reliable operation cannot be guaranteed
