Setting of the transfer rate (transfer speed) via the RS485 interface. All bus participants must
have the same baud rate setting.

1 =
9600 Baud
3 =
38400 Baud

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.
NOTE:
The process data channels for USS, CAN/CANopen and CANopen Broadcast are
monitoring independently of each other. The decision concerning which channel to
monitor is made by means of the setting in parameters P509 and P510.
For example, in this way it is possible to register the interruption of a CAN Broadcast
communication, although the FI is still communicating with a Master via CAN.
P514
CAN baud rate
(CAN baud rate)
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 =
10 kBaud
3 =
100 kBaud
6 =
500 kBaud
1 =
20 kBaud
4 =
125 kBaud
7 =
1 MBaud * (test purposes only)
2 =
50 kBaud
5 = 250 kBaud
*) Reliable operation cannot be guaranteed
