Siemens 420 manual Selection of command/frequency setpoint P0719, Command source

3 Functions Issue 07/04

3.1.2.2Selection of command/frequency setpoint P0719

Parameter P0719 represents a combination of the functionalities of the two parameters P0700 and P1000. Here, it is possible to changeover the command source as well as also the frequency setpoint source via a parameter change. Contrary to P0700 and P1000, for parameter P0719, the subordinate (lower-level) BICO parameters are not changed. This characteristic/feature is especially used by PC tools in order to briefly retrieve the control authority for the drive without having to change the existing BICO parameterization. Parameter P0719 "Selection of command/frequency setpoint" comprises the command source (Cmd) and the frequency setpoint (setpoint).

Table 3-4	Parameter P0719
Parameter values			Significance
		Command source		Setpoint source (frequency source)
0		Cmd = BICO parameter		Setpoint = BICO parameter
1		Cmd = BICO parameter		Setpoint = MOP setpoint
2		Cmd = BICO parameter		Setpoint = Analog setpoint
3		Cmd = BICO parameter		Setpoint = Fixed frequency
4		Cmd = BICO parameter		Setpoint = USS BOP link
5		Cmd = BICO parameter		Setpoint = USS COM link
6		Cmd = BICO parameter		Setpoint = CB COM link
10		Cmd = BOP		Setpoint = BICO parameter
11		Cmd = BOP		Setpoint = MOP setpoint
12		Cmd = BOP		Setpoint = Analog setpoint
..		..		..
..		..		..
64		Cmd = CB on COM link		Setpoint = USS on BOP link
66		Cmd = CB on COM link		Setpoint = USS on COM link

NOTE

The complete list of all of the possible settings can be taken from the parameter list (refer to the parameter list, P0719).

Contrary to parameter P0700 and P1000, subordinate BICO parameters are not changed for parameter P0719. This characteristic/feature can be used during service if the control authority must be briefly and quickly re-assigned (e.g. selecting and executing the motor data identification routine using a PC-based tool).
