Example 1:
AI1 input range -10V ~ +10V
AI1 input range is -10V ~ +10V, and rated speed of motor is 3000rpm. Setting Pr.233 = 1, and
Pr.235 = 20. Please following the situation listed below to learn how to use the parameters.

※
Input +10V to AI1, and read Pr.229 = 4012.
※
Set Pr.230 = 4012.
※
Input 0V to AI1, and read Pr.229 = 2014.
※
Set Pr.231 = 2014.
※
Input -10V, and read Pr.229 = 18.
※
Set Pr.232 = 18.
※
By the equation 3000÷(4012-2014) 1.5 to know that one A/D count is about 1.5rpm.
※
By the equation 20x1.5=30 to know the range of Blind Zone is +/-30rpm.
If the input voltage of AI1 is in the range of 2014+/-20, the motor will not run.
If the input voltage of AI1 exceeds f the range of 2014+/-20, the motor will run, and the min. start
speed of motor will be about 30rpm.
