In the analog feedback close loop system, if there are main reference and auxiliary reference, the main
reference value can be digital voltage, analog and pulse, the auxiliary reference value can be analog and
pulse.
The analog feedback close loop control main reference mode P1.02 can be selected as follows:
0: Digital voltage reference (P8.00) ; 1: AI1; 2: AI2
Digital voltage definition: 0~10V is indicated in digits in parameter P8.00.
The analog feedback close loop control auxiliary reference mode P1.03 can be selected as follows:
0: None; 1: AI1; 2: AI2
The analog feedback close loop control main reference and auxiliary reference calculation P1.03 can be
selected as follows:
0: Main + auxiliary; 1: Main − auxiliary; 2: Auxiliary −50%; 3: Main+ auxiliary−50%; 4: Max; 5: Min
The main reference and auxiliary reference calculation function for close loop reference is the same as
the main reference and auxiliary reference calculation function for open loop reference. For details, refer
to the description of P1.01.
Note: Under the analog feedback close loop control mode, the analog main reference, analog auxiliary
reference, analog main feedback and analog auxiliary feedback cannot be set at the same channel.
