14.3 Setpoint change-over
The inverter receives its setpoint from the selected standard setpoint source. Corresponding
funcons make it possible to change over to other setpoint sources during operaon.
Possible setpoint sources are:
•
Analog inputs
•
Keypad
•
Network
•
Parameterisable setpoints (presets)
•
Digital inputs (congured as HTL input for pulse train or HTL encoder)
•
"Motor potenometer" funcon
•
"Sequencer" funcon
Details
For applicaons only requiring one setpoint it is sucient to dene the standard setpoint
source in the following parameters:
•
0x2860:001 (P201.01): Frequency control: Default setpoint source
•
0x2860:002 (P201.02): PID control: Default setpoint source
•
0x2860:003 (P201.03): Torque control: Default setpoint source
For a setpoint change-over during operaon, the following funcons must be congured. For
details and examples see the following subchapters.
Funcon Info
Acvate AI1 setpoint
0x2631:014 (P400.14)
Acvate analog input 1 / analog input 2 as setpoint source.
4Analog input setpoint source ^ 548
Acvate AI2 setpoint
0x2631:002 (P400.02)
Acvate keypad setpoint
0x2631:016 (P400.16)
Acvate keypad as setpoint source.
•
The keypad setpoint can be changed in the operang mode via the navigaon keys and keypad key.
4Keypad setpoint source ^ 551
Acvate network setpoint
0x2631:017 (P400.17)
Acvate network as setpoint source.
4Network setpoint source ^ 553
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 source of preset setpoints ^ 554
Acvate preset (bit 1)
0x2631:019 (P400.19)
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").
4HTL input setpoint source ^ 565
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".
4Motor potenometer setpoint source (MOP) ^ 559
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.
4Setpoint source segment setpoints ^ 563
Acvate segment setpoint (bit 1)
0x2631:027 (P400.27)
Acvate segment setpoint (bit 2)
0x2631:028 (P400.28)
Acvate segment setpoint´(bit 3)
0x2631:029 (P400.29)
