NETWORK VARIABLES
6.6.1 PID set point (network input SNVT_lev_percent nviInvPIDTarget)
Enter the target value of air volume, temperature, etc. in 0.005% increments.
⋅ Data acceptance timing........... At network variable receive (nv_update_occurs event)
For example, when setting 30°C as the set point using a 10°C/0% and 50°C/100% detector,
As the PID set point, input 50.00%.
Data Name Initial Value Range Increments
nviInvPIDTarget 0.000% 0.00% to 100.00% 0.005%/bit
REMARKS
• Control can not be exercised at less than the minimum resolution (0.01%) of the inverter.
• When the value outside of the range is input, the input value is made invalid and the inverter operates with the value
set last time.
