Selection Of Setpoint Source - Lenze i55AE125B Manual

Basic setting

Selection of setpoint source

7.4 Selection of setpoint source
The selected "setpoint source" serves to provide the inverter with its setpoint. The setpoint
source can be selected individually for each operating mode.
Possible setpoint sources are:
Analog inputs
•
Keypad
•
Network
•
Parameterisable setpoints (presets)
•
Digital inputs (configured as HTL input for pulse train or HTL encoder)
•
"Motor potentiometer" function
•
"Sequencer" function
•
Details
For applications only requiring one setpoint it is sufficient to define the standard setpoint
•
source in the following parameters.
For applications requiring a change-over of the setpoint source during operation, the func-
•
tions for setpoint change-over have to be configured accordingly.

Info
Selection of the standard setpoint source for operating mode "MS:
Velocity mode".
• The selected standard setpoint source is always active in the operat-
ing mode 0x6060 (P301.00) = "MS: Velocity mode [-2]" when no set-
point change-over to another setpoint source via corresponding trig-
gers/functions is active.
4Setpoint change-over
^ 546
The setpoint is specified locally by the keypad.
• Default setting: 0x2601:001 (P202.01)
• Use the
and navigation keys to change the keypad setpoint
(also during running operation).
The setpoint is defined as analog signal via the analog input 1.
4Analog input 1
^ 597
The setpoint is defined as analog signal via the analog input 2.
4Analog input 2
^ 601
The digital inputs DI3 and DI4 can be configured as HTL input to use an
HTL encoder as setpoint encoder or define the setpoint as a reference
frequency ("pulse train").
4HTL input setpoint source
^ 565
The setpoint is defined as process data object via the network.
4Configuring the network

For the setpoint selection, preset values can be parameterised and selec-
ted.
