Note: When the corresponding frequency of the combination value f
com
exceeds the upper or lower limit
of the frequency, the output frequency will be restricted to the upper or lower limit.
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 may be selected as follows:
0: Digital voltage reference (P8.00) ; 1: AI1; 2: AI2; 3: AI3; 4: DI
Digital voltage definition: 0~10V is indicated in digits in parameter P8.00.
The analog feedback close loop control auxiliary reference mode P1.03 may be selected as follows:
0: None; 1: AI1; 2: AI2; 3: AI3; 4: DI
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.
In the analog feedback close loop system, the main feedback and auxiliary feedback can be analog or
pulse.
The main feedback and auxiliary feedback calculation function for process close loop feedback is the
same as the main reference and auxiliary reference calculation function for process close loop reference.
For details, refer to the description of P1.01.
The analog feedback close loop control main feedback mode P1.05 may be selected as follows:
1: AI1; 2: AI2; 3: AI3; 4: DI
The analog feedback close loop control auxiliary feedback mode P1.06 may be selected as follows:
0: none; 1: AI1; 2: AI2; 3: AI3; 4: DI
