Changing the setpoint source during operation

The inverter receives its setpoint from the selected standard setpoint source. For applications requiring a change-over of the setpoint source during operation, the functions listed below must be configured.

Details

For further details and examples, see the following subchapters.

In case of an activated network control, the functions for setpoint change-over are not active! If in case of network control no setpoint is defined via the network control word, the standard setpoint source is active.

Function	Info

Priority of the setpoint sources

Since only one setpoint source can be active at a time, the following priorities apply:

Flexible I/O configuration or keypad control active 0x2631:037 (P400.37) = FALSE	Network control active 0x2631:017 (P400.17) = FALSE 0x2631:037 (P400.37) = TRUE
Prio 1: Functions for setpoint change-over The priority of the functions results from the assigned triggers (in the order of the selection list): 1. Constant TRUE [1] 2. Digital input 1 [11] 3. Digital input 2 [12] 4. Digital input 3 [13] 5. ...	Prio 1: Setpoint source selected via network control word Control the inverter via network
Prio 2: Set standard setpoint source – 0x2860:001 (P201.01): Frequency control: Default setpoint source – 0x2860:002 (P201.02): PID control: Default setpoint source	Prio 2: Set standard setpoint source – 0x2860:001 (P201.01): Frequency control: Default setpoint source – 0x2860:002 (P201.02): PID control: Default setpoint source

Example of allocating priority

Parameter	Designation	Setting for this example
0x2631:014 (P400.14)	Activate AI1 setpoint	Digital input 5 [15]
0x2631:016 (P400.16)	Activate keypad setpoint	Digital input 4 [14]

Digital input 4	Digital input 5	Active setpoint source
FALSE	FALSE	Standard setpoint source set in 0x2860:001 (P201.01)
FALSE	TRUE	Analog input 1
TRUE	FALSE	Keypad
TRUE	TRUE	Keypad (since "Digital input 4" trigger is higher in the selection list than "Digital input 5" trigger)
