Table 1: Settings for the first parameter set (automatic mode)
Parameter Code  | Parameter Name  | Parameter Value  | 
0-10  | Active Set  | [9] Multi Set-up – operation with multiple parameter sets  | 
Perform preliminary settings as per the section "Initial Parameterization of the Frequency Converter and Basic Parameters"  | ||
3-02  | Min Command  | [0] min working level or min signal level from the sensor (see sensor labeling)  | 
3-03  | Max Command  | [10] max working level or max signal level from the sensor (see sensor labeling)  | 
3-15  | Task Source 1  | [0] No function – no (not used, otherwise the speed command will be the sum of tasks from sources 3-10, 3-15, and 3-16)  | 
3-16*  | Task Source 2  | [0] No function – no (not used, otherwise the speed command will be the sum of tasks from sources 3-10, 3-15, and 3-16)  | 
5-12*  | Digital Input Function Terminal 27  | [2] – coast inverse – not used (otherwise, under factory settings, the function is coast inverse – i.e., when there is no signal from terminal 12 at terminal 27, the mechanism in coast mode (start command is ignored))  | 
5-11*  | Digital Input Function Terminal 19  | [23] – set up select bit 0 – parameter selection for automatic/manual modes  | 
6-91  | Analog Output  | [12] Feedback – feedback signal  | 
2-10  | Braking Function  | [1] Resistor brake – braking with braking resistor  | 
1-00*  | Configuration Mode  | [3] Process – PI controller mode  | 
7-20*  | Task Source for PI Controller (for VLT Micro)  | [2] Analog input 60 – analog input terminal 60  | 
7-30  | Normal/Inverted Operating Mode of Controller  | [0] normal (mechanism speed is higher with a + error (task – signal from the sensor)) (pressure)  | 
7-33*  | Proportional Coefficient of the PI Controller  | [1] – adjustable for application  | 
7-34*  | Integral Coefficient of the PI Controller  | [8] – adjustable for application  | 
3-100*  | Integral Coefficient of PI Regulation  | Task % from 3-03 – task support level in % from maximum value  | 
* Be sure to enter/check the values of these parameters
