The address under which the inverter is addressed by „COMBIVIS" or another control
is adjusted via Sy.6. Values between 0 and 239 are possible, the default value is 1. If
several inverters are operated on the bus simultaneously, it is absolutely necessary to
assign different addresses to them, since otherwise it leads to communication failures
because several inverters may answer at the same time.The description of the DIN
66019II protocol (C0.F5.01I-K001) contains further information to this. While loading
the default parameters there is no reset of Sy.6.
Following values for the baud rate of the serial interface are possible:
Parameter value
0
1
2
3 (default)
4
5
6
If the value for the baud rate is changed via the serial interface, it can be changed again
only by the keyboard or after adapting the baud rate of the master, as no communication
is possible with different baud rates of master and slave.
Should problems occur at the data transmission choose a transfer rate of maximal
38400 baud.
With the internal baud rate the transmission rate is defined between operator and
inverter. Following values are possible (dependent of the inverter):
Value Baudrate
3 9,6 kBaud
4 19,2 kBaud
5 38,4 kBaud
For a continual check it is possible to trigger an error message of the inverter at the
completion of an adjustable time (0.01...10 s) during which no telegram is received.
The function can be deactivated by adjusting the value „off".
This parameter determines the response to a Watchdog-error. Depending on the selected
setting a message E.buS or A.buS is output (further information in Chapter 6.7.6).
The HSP5 Watchdog-function monitores the communication of the HSP5-interface
(control card - operator; or control card - PC). After expiration of an adjustable time
(0,01...10 s) without incoming telegrams, the response adjusted in Pn.5 is triggered.
The value „off" deactivates the function.
