7.4 Changing the setpoint source during operaon
The inverter receives its setpoint from the selected standard setpoint source. For applicaons
requiring a change-over of the setpoint source during operaon, the funcons listed below
must be congured.
Details
For further details and examples, see the following subchapters.
In case of an acvated network control, the funcons for setpoint change-over
are not acve! If in case of network control no setpoint is dened via the net-
work control word, the standard setpoint source is acve.
Funcon Info
Acvate AI1 setpoint
0x2631:014 (P400.14)

Acvate network as setpoint source.
4Dene setpoint via network ^ 296
Acvate preset (bit 0)
0x2631:018 (P400.18)
Acvate parameterisable setpoints (presets) as setpoint source.
•
15 frequency setpoints and 8 PID setpoints can be set as presets.
•
A preset can be selected binary-coded via the four funcons "Acvate preset (bit 0)" ... "Acvate preset (bit
3)".
4Setpoint presets ^ 87

Acvate preset (bit 2)
0x2631:020 (P400.20)
Acvate preset (bit 3)
0x2631:021 (P400.21)
Acvate setpoint via HTL input
0x2631:022 (P400.22)
The digital inputs DI3 and DI4 can be congured as HTL input to evaluate the signal of a cost-eecve HTL
encoder or a reference frequency ("pulse train").

Acvate MOP setpoint
0x2631:025 (P400.25)
The "Motor potenometer" funcon can be used as an alternave setpoint control that is controlled via two
funcons: "MOP setpoint up" and "MOP setpoint down".

Acvate segment setpoint (bit 0)
0x2631:026 (P400.26)
Acvate parameterisable segment setpoints as setpoint source.
•
The four funcons "Acvate segment setpoint (bit 0)" ... " Acvate segment setpoint´(bit 3)" enable a set-
point change-over to a segment setpoint parameterised for the "sequencer" funcon during normal opera-
on (no sequence acve).
