3.1.2.2 Selection 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).

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).
